Network Drops on Unlocked SGS on Telus Experiencing - Galaxy S I9000 Q&A, Help & Troubleshooting

Hi Everyone,
I recently puchased a Vibrant from Bell mobility, successfully unlocked it and was using it on Bell. In areas of poor connection whenever I used the data, the network would drop completely and I'd see the circle with the line through it where my network connection is. The voice bars will come back most of the time quite quickly, but data can stay offline for sometime then randomly pop back up.
I've found this happens the most when I'm in doors.
Has anyone else using an unlocked Bell Vibrant on Telus experience the same problems?
I've done hard resets, cleared out all programs, etc. I even went to Bell and returned the handset for a new one. I'm still experiencing the issue on this new handset with absolute no added programs on it.
Any suggestions?
Thanks in advance.

Have the same problem.
The workaround for it seems to be doing the 850 trick. Call quaility is a little worse, but, no dropped calls anymore.
I think it is a telus thing, the way the phone tries to find the reception.

Hey kintap, thanks for the quick response.
I'm not experiencing dropped calls (yet), but when I'm using the internet indoors all connections just drop off and I have to wait for the connections to come back.
It mostly happens when I'm using the browser.
Was your problem similar?
I'll try out the 850 trick.

@meandnotyou are you also in Edmonton/Calgary area?
Telus people on GTA / Vancouver area don't seem to have as much trouble as you guys over at Edmonton/Calgary
that's according to the feedback found in the forum

Hey AllGamer, I'm from Vancouver.
I've tried changing the 850 trick as mentioned and it seems to have been ok since then. I'll keep testing and let you guys know.

It's not just a Telus thing... I'm on Bell in Vancouver and have the same issue as well.
I'm also one of those who are experiencing the comatose problem too.
I believe it's mainly a software issue where the phone has trouble locking on the signals. (I haveny seen any users who unoffically updated to froyo reporting these problems, yet).

+1. same exact problem here. On Bell. Lose signal indoors @ home.. experiencing comatose problem, usually when there is no signal. 850 trick doesn't seem to work for me. Re-flashed to JH2, factory wipe. *#272*imei# trick, etc.. all started a week ago. was working perfectly for 1st month. seems to be getting worse/more frequent.
anyone want to buy my SGS?

Wow that sucks. I was gonna wipe my phone earlier too, but read that it doesn't help...
Have you tried getting a new SIM card from Bell? When you did the 850 trick, did you double just that it was just the 850 that was selected? You can try what I selected, after selecting just only the WCDMA 850, go into the combi band and select the GSM 850 band too, that way it has a "backup". Hope this helps you if you haven't tried it already

Hey Louie604. Thanks i'll try it now. I'm a noob to Android. did the 805 trick work for you? if that doesn't work, I'll try asking for a new SIM card. When I'm outdoors, signal is strong and I have no freezing problems - only when indoors and poor signal. in Van as well.

Yea, the 850 trick worked for me (improved battery life while idling too).
Currently I'm testing just the 1900 band to see if it still locks up on me, but I won't know till I get home. I'll be posting my results in the comatose topic
http://forum.xda-developers.com/showthread.php?t=775017
Also, I should mention, when you're setting the band, make sure you do it under the service mode, otherwise the settings don't save (from what I read).
This was the instructions I followed...
1. on the key pad, type *#*#197328640#*#*
2. Select [1] Debug Screen
3. Select [8] Phone control
4. Select [7] Network control
5. Select [2] Band selection
6. Select [2] WCDMA band []
7. Select [6] WCDMA 850
After doing the above steps, just go into the "Combi Band" and select the "GSM 850" also... just in case it ever needs to fall back

Louie604, thanks. ok I think I may have missed something. In step 7 above, I have WCDMA 850 (FDD V) option under [5] not [6]. there is no [6]. As well, after *#0011#, I see that I'm still under WCDMA 1900 band 2, even after following your steps above. I double checked my band selection settings and they were saved. Does this mean anything?

Sorry, yes it it under [5]. (I just copied and pasted it but never paid attention to the fine details )
That's strange tho. Perhaps try this:
1) Select [1] Automatic
2) Go Back and then go into [4] Combi Bands and check to see that all are selected EXCEPT for [7] WCDMA 900 (FDD VIII)[] (It doesn't select it for me and I assume the same for you since you're in Vancouver too)
3) Go back and select [2] WCDMA Band []
4) Select [5] WCDMA 850 (FDD V)[*] (It should then say it's selected and when you go back, it should be the only one with the [*])
5) Go back out to the "Band Selection" menu and select [4] Combi Bands []
6) Select GSM 850 [] -- When you go back after selecting it, you should see in the list this:
Code:
[1] GSM 850 [*]
[2] GSM 900 [ ]
[3] DCS 1800 [ ]
[4] PCS 1900 [ ]
[5] WCDMA 2100 (FDD I)[ ]
[6] WCDMA 1900 (FDD II)[ ]
[7] WCDMA 900 (FDD VIII)[ ]
[8] WCDMA 850 (FDD V)[*]
Once you see those, you may simple exit out and then check again. If anything you can turn on airplane mode and then back off or restart you phone and see if it's at the 850 band.
Hope this helps

Got it. Thanks.

Hey guys,
Just wanted to give an update. Since I did the band change using the 850 trick (same day I made the original post), I haven't experienced any complete network drops or comatose issues.
I am now traveling though and finding the connection to be lacking. I imagine it's because I've hard set the band, so reverting while traveling to see if it has any effect.

BandSel_BAWWE_140921.sa.CAB

Is anyone else running this cab file??
Before loading it, I pulled it apart with a cab editor to see what it was. I was very excited to see that it uncovered the radio band selction capabilities, so I quickly installed it.
But this where things got funny. I refuses to give me the option for the for GSM 1900, although it is clearly called out in the registry edits the cab lays down. I am running the 1.13 radio, with system 1.40.00, and was wonder if anyone else can verify this as a problem? I am wondering if this is a software issue in either the cab, system, or radio... Or to my horror is the SX66 retarded to triband???
-Chris
Ok, looks like TheLastOne answered my question in another post. Funny that the site search failed to turn this up:
1) Phone Band Selection: BandSel_BAWWE_140921.sa.CAB
- I've played with this a bit, their cab is actually ****ed up, as they have tried to get 6 selections onto the page when only 5 are possible. Through the registry you can have any band configuration you want selectable. I personally LOVE this feature.
GSM 1900 is the 6th selection, hence it doesn't show up. But this now leaves a glaring question, what are ALL the selectable options? I note the 900/1800 option with a value of 3, but is there a 850/1900 option(This would be prefect when I go to aruba), and what is that value??
GSM900 has a value of 1
GSM1800 has a value of 2
GSM900/1800 has a value of 3
GSM1900 has a value of 4
Automatic has a value of 7
gsm850 has a value of 8
So, what are values 5 and 6?? I could set those values, but I have no idea how I'd check to see what band I am current using. Anyone got any thoughts?
-Chris
Either 5 or 6 is 850/1900, from my tests, but I forget which.
If you don't mind, how did you determine that?
-Chris
In my location, I have access to two GSM networks, one which is exclusively 1900 and the other is 850. Set to either 5 or 6, I could get on both. (So I'm not positive it's EXCLUSIVELY 1900 and 850, since there is no 900 or 1800 here to test).
I did this a bit ago, so I don't properly remember.
The value is a bitmask:
bit 1: 900
bit 2: 1800
bit 3: 1900
bit 4: 850
so 5 means 101b - 1900+900
6 means 110b - 1900+1800
Setting 7 would make GSM to use 900, 1800, 1900
Probably the GSM part also tries to register on 850Mhz when 1900 is selected.
Mamaich,
You rock. You never cease to amaze me. Very cool, thanks.
-Chris
Can you post a link to this CAB file?
Modified Band Select CAB for USA
I modified the CAB for USA only 850, 1900 and Auto
I ran the updated CAB file you posted here, seems to be working ok, although signal strength (on the new bands) seems to be weaker than what I had before installing the cab. I am wondering, is there ever away to revert back to the original band options or settings ?
I am wondering the same thing, because NONE of the 3 options i had available to me when I installed this (Auto, GSM 850/1900 (NA), GSM 900/1800(Euro/Asia) were selected.
When I selected Auto, I began ROAMING, and I'm not certain why. The only way I know of to return this back to factory state is to hard reset.
Does anyone have THE ORIGINAL CAB, before the mods were made so that ALL options were available?? I'd really like to have that cab so that I can see what option my PDA2k on Cingular was using...
Here is the original CAB file, it did not work on my SX66 (see the first few posts on this thread) so I modified it to use only 850/1900 and Auto. I have had no problems with the modified CAB. Signal strength has not been degraded.
thanks, Cruzzer.
the modified CAB put me into permanent ROAM no matter what frequency I chose (or killed the phone entirely because there wasn't a 900/1800 tower).
I managed to get a hold of Chris and he helped me make some registry mods that gave me the original functionality back.
Interestingly enough, I had to put the phone thru a couple of different SR's before it would stop roaming, even after switching back to JUST 850.
Goofy, huh?
Care to go over the registry edit you made? Thanks.
Question
First of all, thans for the Band Select created by Cruzzer for US users. After I install his band select, it's the first time that I can use my phone in my office located in a basement. But I have a problem. In his band select, there are three options, automatic, GSM 850, and GSM 1900. When I selected automatic, my phone couldn't find the network. But when I selected GSM 850, it works perfectly. At first, I understand that by selecting my phone to automatic, my phone should search both GSM 850 and GSM 1900. But I don't know why it always show no network. Did I do anything wrong?
By the way, my phone is O2 XDA IIs brought from Thailand. (O2 Asia)
I believe that there is a bug in BA when working with GSM850.
In fact, automatic should search between GSM850, 900, 1800 and 1900.
Usually when using "automatic" where GSM850 networks exists, makes BA not being able to find any network.
Are you using WM2003SE ?
JP
Yep WM2003SE
Yes, I'm using WM2003SE.
I also tried another band select created by one of our members in http://forum.xda-developers.com/showthread.php?t=297099 His band select gives four options:
1. automatic
2. GSM 850/GSM 1900 (north america)
3. GSM 900/GSM 1800 (Europe)
4. Reset Values to Zero
When I selected GSM 850/GSM 1900 (north america), my phone had no signal. So, right now I have to go back to BandSel_BAWWE_140921.sa.us and manually select GSM 850.
Yes, unfortunely, that seems to confirm my teory.
If it works for you at 850, keep at that. Just remember that if you upgrade to WM6, band selection will not be available and it will be locked to your choice done in WM2003, in this case 850.
Your BA, will no longer be quad-band (the same as mine).
JP
Too bad
Thanks for confirming the bug in BA. Too bad. I want to upgrade to WM6 but I know there is no way to select which band in WM6. So...I'm stuck with WM2003SE. I wonder, can we edit the registry to manually select the GSM band in WM6?
I've tryed and some other did also, but it seems that both the .cab and also registry tweaks for band selection do not work on WM6.
It does not mean that you will have a problem with WM6, but rather that the band that you have selected on WM2003 will remain "locked" when using WM6 and cannot be changed.
In my case, i'm using the 900/1800 band selection and it works just fine with WM6 (i've used Helmi's and now i'm using Xplode's) but i cannot select 850 for example.

[Q] Looking for a 2.2 ROM that will last more than 8 hours...

Hi Guys,
I am new to the Galaxy S Vibrant and while I love the phone I can't get 8 hours on a charge. I've played around with the Doc Froyo XWJPA v7.6.2 / XXJPO v7.6.2 ROM (the one for North America) and maxed out at about 4 hours and now I'm on [ROM][FROYO] Tayutama Edition v1.0.2 (I9000) and max out at about 8 hours.
I need a ROM that is going to last me at least the work day. I'm coming off a 3GS that could do a whole day no problem.
As far as usage goes, I receive email all day long, off and on wifi (3G whole time), make a few calls, receive a few texts and spend a bit of time on the browser.
The problem I have is that the phone is dead before my work day is over.
Any suggestions? I'm open to either a new ROM or a different 2.2 phone altogether.
I'm doing my best NOT to buy the iphone 4 and I don't want to hear anything about not having a lot of apps, having to use battery programs, etc. All that is doing is making excuses for the phone and not helping me find the solution.
If it makes a diff I'm on Rogers in Ontario.
Thanks!
I tried a few combinations too, the best one i have now without use of a battery saver program gave me at least 16 hours of use, and with the saving above 24 hours of use, and even 2 days standby.
I think i have a mix running atm, since a few methods of flashing didn't succeed.
Check my signature, i also ran a ryanza lagfix + ext2
Filenames i used:
Phone : CF-Root-JP6-v1.2-Busybox-1.17.1.tar

Easiest way, flash only the modem. JPM, is meant to use less than JPP with DATA use.
Next step if that doesn't work, forget about flashing an entire new ROM, besides you prob don't want to do that and it's an inconvenience.
Just flash Speedmod Froyo through ODIN if you don't have CWR setup.
See http://forum.xda-developers.com/showthread.php?t=822756.
speedmod-kernel-i1_2-250hz-r2-CWM is pretty good and stable.
It's the place to see what is up with battery life! Hardcore is working hard at it, is very dedicated and helpful.

True, but JPD should use even less power... don't know if GPS still is as good as with JPP or JPM..

Very true, have been using that kernel all day now (yeah i change kernels very often ) and my battery is still 67% after a whole day work..
Use Doc's JPO 7.6.2 with speedmod and JPP modem, all tweaks ON and ext4 fs
My only advise to you would be to switch the auto updares on gmail / tweetdeck to 1 hour as opposed to 15 minutes.
Also i keep data network mode disabled.
My battery is rubbish still but i can get about 14 hours.
I do use the phone heavily though, so I am sure if I don't use it I would get a lot of standby

Sent from my GT-I9000
In my experience it does help a lot to do a clean 2.2 install via kies and flash a slim rom like docs over it. Then hardcores 200 hz kernel with activeted tweaks but no lagfix. I need to restart the phone every 2 or three days and if lag persists lagfix and unlagfix it to repartition rfs. This gives me more than two days of usage, sometimes up to 4. Oh and use advanced task killer on agressive settings! The phone is smooth, no need for a lagfix for me, especially not for the price of heavy battery drain

You are doing something wrong... I've been on 7.6.2 and previous variants for a long while now.. Battery life has never been an issue. You are in canada like me so you have a Galaxy S i9000m. Long story short, I've got the same phone, stock JPP modem that comes with doc's rom. No battery life issues what so ever and I use my phone ALL day since its synched to my work's webmail and we get +/- 50-200 emails a day and its set on push notification polling.
Anyways, the trick is to find what works for you but I have a feeling there's something you aren't doing right if you are getting battery life THAT bad.

What am I doing wrong? I'm not sure what mistake I could have made? The phone works fine so I didn't mess up in flashing anything. I've been on multiple ROMS that have all worked... so my process is fine.
I just need to find a ROM that isn't killing my battery with some mysterious silent background process or figure out if my battery/phone is defective in someway.
This morning before I took my phone off the charger I enabled lag fix in the CWR program and only managed to get about 4 hours on my current ROM.
I need this phone for work and like you I receive 100+ emails per day. My iphone was fine (as was my BB) but this android is not cutting it. I just need to find a good rom or decide that this phone is not up to the job.
A lot of my friends who came from the 3GS swears that the SGS lasts significantly longer in terms of battery life while having the same things pushed, you probably have more things going on with your SGS as compared to your 3GS before thats why the battery life is worse on your end.
On average I can get 7-8hrs of HD movie time before my phone goes off so that 4h battery life of yours is doing something that draining the battery faster than a screen time of 8hrs.
I have a very technical solution..
Buy a spare battery! Or even the ugly ass battery backplate. If you want to be able to use the phone non stop and not worry about battery then no matter how much rom/configuration tweaking there is the simple fact is that this display eats battery.. for breakfast lunch and dinner.. so find a battery solution rather than a rom solution.
I brought a second battery and if i have to go out for an extended period of time and i know my phone use will be heavy i take it.. simples..

are you using a facebook account or something like that too? or just a google account only? sounds like you've got some rogue app going nuts. also, check your display settings. switch off all animations and auto brightness. set the brightness down low.
did you do a full battery cycle btw and reset the battery stats?

This sounds like something my girlfriend did with her SGS. I taught her how to use Mobile AP and she loved it, however she didn't understand that she needed to switch it off and her battery would last about 7-8 hours.
Please check this isn't enabled as this drains battery considerably.
There is this thing called spare battery.
Or try speedmode with support of down to 200Mhz all the roms with ext4 will drain faster ext2 is said to be same as RFS
Actually I have more of another question than a solution here...
I'm speculating if the same modem would react differently against different telco providers out there. I'm residing in Malaysia and using DIGI as my telco provider. What was claimed by this forum (12/14/16 hours) of standby is unheard of despite changing different roms and tweaks.
What I realised was when I go 3G or 3.5G the battery gets drained like an open faucet - however, EDGE and WIFI is still ok. Perhaps the telco here uses different hardwares and requires my device to work extra hard to obtain 3G signals ? I don't know. Someone who have experienced this may actually help answer this side of the story though.
Hi, I had an problem with fast battery drainage as well. I believe I traced it to the bands that the phone was trying to access. I am also on Rogers.
Go to the dialpad, enter *#2263# to enter BAND SELECTION.
There are four choices. Try to get them to look like this:
[1] AUTOMATIC []
[2] WCDMA BAND [*]
[3] GSM BAND []
[4] COMBI BANDS []
Under [2] WCDMA BAND, should aim for:
[1] WCDMA ALL[]
[2] WCDMA 2100(FDD I)[]
[3] WCDMA 1900(FDD II)[*]
[4] WCDMA 900 (FDD VIII) []
[5] WCDMA 850 (FDD V)[*]
Under [3] GSM BAND[], only [2] GSM 850[*] is selected.
Under [4] COMBI BANDS[], selected items are 1, 6, 8 as below:
[1] GSM 850 [*]
[2] GSM 900[]
[3] DCS1800[]
[4] PCS1900[]
[5] WCDMA 2100 (FDD I)[]
[6] WCDMA 1900 (FDD II)[*]
[7] WCDMA 900 (FDD VIII)[]
[8] WCDMA 850 (FDD V)[*]
I'm no expert, but using the battery history service menu:
*#*#4636#*#*
it seemed that the phone was using up spending a lot of time searching on bands that Rogers wasn't using. Before I made these changes, under BAND SELECTION, my phone had
[1] AUTOMATIC [*] selected.
As well, under [2] WCDMA BAND[], looked like this:
[1] WCDMA ALL[]
[2] WCDMA 2100(FDD I)[*]
[3] WCDMA 1900(FDD II)[*]
[4] WCDMA 900 (FDD VIII) [*]
[5] WCDMA 850 (FDD V)[*]
and under [3]GSM BAND[]:
[1]GSM ALL[]
[2]GSM 850[*]
[3]GSM 900[*]
[4]GSM 1800 [*]
[5]PCS 1900[*]
[4] COMBI BANDS[]:
[1] GSM 850 [*]
[2] GSM 900[*]
[3] DCS1800[*]
[4] PCS1900[*]
[5] WCDMA 2100 (FDD I)[*]
[6] WCDMA 1900 (FDD II)[*]
[7] WCDMA 900 (FDD VIII)[*]
[8] WCDMA 850 (FDD V)[*]
Here's how I changed it:
1. make sure that under BAND SELECTION [1]AUTOMATIC[*] is selected.
2. select [4]COMBI BANDS, make sure all the bands are selected. If any are missing, such as [8]WCDMA 850 (FDD V)[], just click on them to add, and you'll see "Add WCDMA_W850[*] If you want to add other bands in present bands, choose band that you want again". Use menu key, then select "back", then back out in to the main band selection screen again.
3. select [2]WCDMA BAND[] submenu. You should see:
[1] WCDMA ALL[]
[2] WCDMA 2100(FDD I)[*]
[3] WCDMA 1900(FDD II)[*]
[4] WCDMA 900 (FDD VIII) [*]
[5] WCDMA 850 (FDD V)[*]
4. select [5] WCDMA 850 (FDD V)[*]. Should see: Select WCDMA_W850 Only [*]. back out (menu, back). Now should see:
[1] WCDMA ALL[]
[2] WCDMA 2100(FDD I)[]
[3] WCDMA 1900(FDD II)[]
[4] WCDMA 900 (FDD VIII) []
[5] WCDMA 850 (FDD V)[*]
5. back out to BAND SELECTION again. Should look like this:
[1] AUTOMATIC []
[2] WCDMA BAND [*]
[3] GSM BAND []
[4] COMBI BANDS []
enter [4]COMBI BANDS[], should look like:
[4] COMBI BANDS[]:
[1] GSM 850 []
[2] GSM 900[]
[3] DCS1800[]
[4] PCS1900[]
[5] WCDMA 2100 (FDD I)[]
[6] WCDMA 1900 (FDD II)[]
[7] WCDMA 900 (FDD VIII)[]
[8] WCDMA 850 (FDD V)[*]
This is showing that your phone will only seek service on WCDMA 850, which Rogers happens to use.
You can back out with menu, back, menu, end at this point, and check what band your phone is using:
To check what band your phone is using, from the dialpad, *#0011#. You could, for example, restrict your phone to WCDMA 850 and see if it can pick up a signal.
I went back and added, under COMBI BANDS, items [1] and [6] as previously mentioned above:
[1] GSM 850 [*]
[2] GSM 900[]
[3] DCS1800[]
[4] PCS1900[]
[5] WCDMA 2100 (FDD I)[]
[6] WCDMA 1900 (FDD II)[*]
[7] WCDMA 900 (FDD VIII)[]
[8] WCDMA 850 (FDD V)[*]
I noticed that when I added these bands under [4]COMBI BANDS, that [2]WCDMA BAND[*] changed to:
[1] WCDMA ALL[]
[2] WCDMA 2100(FDD I)[]
[3] WCDMA 1900(FDD II)[*]
[4] WCDMA 900 (FDD VIII) []
[5] WCDMA 850 (FDD V)[*]
I notice that my phone will sometimes use 850 and sometimes 1900 on Rogers.
Again, I'm not sure if this will help you, but it might be worth a shot. The battery history screen is also useful *#*#4636#*#* and checking partial wake usage and network usage since last unplugged to see which programs are using most of the battery. It was from this that I figured out the dialer was using a lot of the battery. It could also be some other network intensive programs such as a twitter client.
Please report back as I'm interested to know if this helps at all. Cheers!
The battery meter isn't lying when it says the Display is using 90% of your battery. Changing the sync intervals doesn't make that much of a difference to me - the real difference its the amount of time the screen is on and the brightness its set to.
I'm using Docs V6 JP6 Rom and I easily get a full day of use. I'm only using the 850 band though and nothing else. My brightness never goes above 38% either.
My best case broken down is this...
Phone on for 29hrs.
3hrs actual screen on time.
48min of talk time.
and misc stuff the rest of the time.
Right now I'm at...
36% remaining, 14.5hrs since unplugged, 1hr talk time and 1hr 17min screen on.
Keep an eye on your reported "Time without signal", that will nuke your battery very quickly. If you run a 2.1 modem file with froyo you may get 100% "Time without signal", that's no good.

[Q] I9000T / I9000M OEM Antenna module?

I know I should search first before post but believe me, I'm not a guy who like to ask dummy questions without an extensive search before.
Also probably this goes in Accessories, but is a question and is a part not accessory, so, MODs.... where?
Ok... no looking deeply at specifications of i9000, cost me to have an expensive very useless GSM Galaxy, because 3G in my my country is 850MHz.
You can say something about Wifi, but who doesn't hate the obsolete EDGE?
I tried almost everything to mod the Modem or radio frequency and its simple: it is impossible without a hardware modification.
Well, I found this thread: http://forum.xda-developers.com/showthread.php?p=8395614#post8395614
And the following:
started obsessing me (you know how you feel when you find a possibility to fix something than you already give up).
Finding the module that says GT-i9000T will fix my issue, and I dont care about warranty ( all my gadgets get warrant void after less than month).
This module should support 850MHz perfectly.
I google that end to end, cnn.cn gsm4world.us and like 3 or 4 more stores searching for the damn module, to replace it in my i9000.
Searched here in all Galaxy sections... nothing found.
But maybe someone else knows a complete store to get this part.
Or maybe someone knows where to find cheap dead phones to just take out the module part for my phone.
Compatibility? Nah... I think thats the only difference between i9000, i9000t and i9000m ("T" and "M" uses the same module)
I just need to flash a 850MHz enabled ROM (like ColdMOD's) and start having fun.
If someone here has a Bell i9000m or a i9000t for parts to offer I'm willing to buy it or just the part.
Or please can someone tell me a good store to search for it.
Thanks in advance.
[Also, if you think that I'm enough stupid and this replacement not gonna work, let me know why]
Cheers
No Ideas....?? Where can I possibly get this part?
this place http://www.globaldirectparts.com/ has a lot of replacement parts for the galaxy, but not the radio - maybe you can email them and ask if they could get one though? or where else to look?
I've been through that... I need to catch 1700/2100, so I thought about the t-mobile vibrant antenna... The thing is you don't just need to change the antenna and the.module, you also need to change.a.duplexor inside.the phone.... + at directparts you need to buy a minimum of 500 antennas and 5 modules... Personnally I gave.up I'll try to trade my phone for an european i9000 or a t-mobile vibrant on a classified ads website

Did you have any luck? I myself have been trying to figure out if i can modify my i9000 which is 900/2100mhz compatible to a i9000t/m which has the 850mhz instead of 900mhz.
After disassembling one which i need to replace the screen in, I've found that the antenna module sits in the rear housing, and makes contact only by the two right hand contacts on the board you have pictured.
I am curious as to weather the 850mhz models utilise the other contact on the left side of the board instead of one of the others and maybe some how this determines the frequency set of the rf module.
Its probably an unlikely solution, but if anyone can direct me to a picture or somewhere that sells antenna modules for the i9000t or i9000m it would be appeciated
thanks
I haven't test below steps myself, but it make sense to fix this issue.
Phone companies make Cell Phones for Europe as well as United States, but for sure, to not waste money in making different Chip Boards that can handle different kind of Frequencies, they just make the Same Identical Phone and just enable or disable some Functions.
In the United States, some carriers, in my case i have a contract with AT&T, use 3G only in the 850Mhz Band, but if you bought your Phone Unlocked and like me it came from Europe, the 850Mhz Band is disabled, so you just have to Enable the 850Mhz Band Frequency in order to be able to pick up the 3G Frequency of you Carrier here in the US.
Here is how you do it:
Open the Phone Screen and Type the following code:
* # * # 1 9 7 3 2 8 6 4 0 # * # *
The phone will automatically take you to a screen called:
SERVICE MODE
AND YOU WILL SEE THESE OPTIONS:
----------------------
[1] DEBUG SCREEN
[2] VERSION INFO
[3] UMTS RF NV
[4] GSM RF NV
[5] AUDIO
[6] COMMON
----------------------
all these options are written very very small so you will have to touch the screen very accurately to get the right one... so select them in the following order:
[1] Debug Screen
+
[8] Phone Control
+
[7] Network Control
+
[2] Band Selection
Once you Tap on "Band Selection" you will have a screen stating these 4 Options:
-------------------------
= BAND SELECTION =
[1] Automatic [*]
[2] WCDMA Band []
[3] GSM Band []
[4] Combi Bands []
-------------------------
The Asterisk ' * ' indicates what option has been chosen, in this case the selection is on "AUTOMATIC" which is correct: the Phone will pick the best Network to work, we just have to make sure that the Phone is searching in all the Possible Networks because by Default some of them are Disabled.
So Tap on:
[2] WCDMA Band []
and on the screen you will see appearing the following Options:
----------------------------------
= WCDMA BAND =
[1] WCDMA ALL []
[2] WCDMA 2100(FDD I) [*]
[3] WCDMA 1900(FDD II) [*]
[4] WCDMA 900(FDD VIII) [*]
[5] WCDMA 850 (FDD V) []
-----------------------------------
In my case, since the Telephone comes from Europe, the 850 Band is not enabled and you can tell that by the fact that it doesn't have the ' * ' beside it.
JUST TAP ON
[5] WCDMA 850 (FDD V)[]
the phone in about a second will tell you that the Option has been Enabled.
~~~To Go Back DO NOT USE THE "LOOPED ARROW" Button~~~
=== PRESS THE "MENU" BUTTON
and select "BACK" ===
now on the screen you should see the Asterisk beside all the Frequencies, like this:
----------------------------------
= WCDMA BAND =
[1] WCDMA ALL []
[2] WCDMA 2100(FDD I) [*]
[3] WCDMA 1900(FDD II) [*]
[4] WCDMA 900(FDD VIII) [*]
[5] WCDMA 850 (FDD V) [*]
----------------------------------
Now, just to make sure that we did everything right, let's press again the "MENU BUTTON" and select again "BACK" so we go back to the
" =BAND SELECTION= " Screen:
-------------------------
= BAND SELECTION =
[1] Automatic [*]
[2] WCDMA Band []
[3] GSM Band []
[4] Combi Bands []
-------------------------
This time, let's choose a different Option:
Tap On:
[4] Combi Bands []
and you will see a screen giving many more Bands Options like this:
----------------------------------
= COMBINATION BANDS =
[1] GSM 850 [*]
[2] GSM 900 [*]
[3] DCS 1800 [*]
[4] PCS 1900 [*]
[5] WCDMA 2100(FDD I) [*]
[6] WCDMA 1900(FDD II) [*]
[7] WCDMA 900(FDD VIII) [*]
[8] WCDMA 850 (FDD V) [*]
----------------------------------
Make sure that there is the ' * ' beside the "WCDMA 850 (FDD V)" if you don't see it, Tap on that Option so that it will be enabled.
And then go Back (remember you have to do that with the "MENU BUTTON" and not with the "LOOPED ARROW" Button) and make sure that all the Bands have been enabled.
If all the 8 Different Bands Options have the Asterisk beside it, you have successfully enabled all the 3G Bands available and now you will be able to access the 850Mhz 3G Network Spectrum.
ONCE YOU ARE DONE PRESS THE "MENU" BUTTON AND CHOOSE: " END "
This is it, for me it worked, now i am using my Samsung Galaxy S with AT&T 3G and for now, i didn't have any problem... i don't know if in the future AT&T will "'*****'" about this, but i really hope not.

[Q] How do I disable 1900 band and keep only 850 + 2100 ?

Is there a way to disable the 1900 3G band and just keep 850 and 2100? Whenever my phone (i896 rogers running JK4 modem) switches to 1900, I lose 3G connection. It takes a few mins for it to switch to other bands and restore connectivity.
-----------------------------
Rogers i896 Captivate
ROM - Perception 10.2
Kernel - Firebird 2 0.4
Modem - JK4
Dial *#2263# ... (spells BAND). It's likely set to Automatic as the default. Manually select/deselect what you want under COMBI BANDS. If you need to revert it, just reselect AUTOMATIC.

I've never been able to selectively choose options from there, but a workaround would be to just go into the WCDMA bands, select 850 and set that as the only one.
I do that and use HSPA only with my phone.

I had an extremely similar problem recently. Only solution I found was reflashing the modem and reselecting all in band selection. Problem went away after that.

SM-G906S (S805) -- ACTIVATE LTE on AT&T

I am on AT&T and the reason I bought this phone was because, according to the specs in the FCC site, it has LTE Band 17 (which is the most common one for AT&T).
I was only getting 3G (HSPA+) speeds. I followed the following procedure to enable LTE for data and still be able to place/receive phone calls:
Do this at your own risk
Open the dial pad
Type: *#0011# to enter Service Mode (Be very careful with what you do here)
Note: You need to be rooted for this to work
Once in Service Mode, do the following:
Tap the menu button and tap Back
Tap the menu button again and select "Key Input" and enter an upper case Q and press OK
Tap the menu button again and select "Key Input" and enter 4 zeroes (0000) and press OK
Wait from 5 to 15 seconds. You'll see the Main Menu
Choose option [2]: UE SETTING & INFO
Choose option [1]: SETTING
Choose option [1]: PROTOCOL
Choose option [2]: NAS
Choose option [1]: NETWORK CONTROL
Choose option [4]: BAND SELECTION
Choose option [4]: LTE Band Preference
Choose option [7]: LTE ALL (Or you can choose band 17 instead)
Tap the menu button and choose Back (Don't press the back key)
Tap again the menu button and choose Back
Choose option [6]: LTE/WCDMA Mode Only
Press the back key to exit
And that's it: You now have LTE and calls if using AT&T. This won't work with TMobile.
If you reboot your phone, you may need to repeat the steps.

I am confused. I am also on ATT - I bought this phone back when it first came out. All I did was add the ATT APN and then I was able to get LTE just fine. I didn't have to do anything like you described.
So - are you saying you added your APN and still had to go thru all of those steps?

That brings up another question - If I am getting LTE now - does that mean I am already getting data via that Band you mentioned ? Or could it be that I am getting it from some other band? (forgive these noobie type questions - I really don't know that much about this)
and is there a difference between the speeed you can get from any of the different bands?

Try this free app to show you what LTE band you are using
https://play.google.com/store/apps/details?id=net.simplyadvanced.ltediscovery
Most likely if you are on AT&T is band 17.
The higher the frequency the most difficult it is for the signal to travel farther or into building. You'll better results if you are receiving on 700MHz than 2600MHz, but that is determined by your carrier (although there are ways to manually change it)
Yup my AT&T LTE bands weren't activated as well. Had to go through these steps and they worked perfectly!

Thanks for the informatino - I had no idea that some phones had problems connecting to LTE - I personally never have had that issue with any of the TMOBILE PHONES i have used on ATT (Note 3 and my S5) but its good to know this in case it ever happens with a future phone.
anyway, for grins and gigglesI got the app suggested - but I can't see in the app where it says what band I am using?
I attached a screen shot - can you tell me what I should be looking for?

Thanks - Got it - and you were right, Band 17
Hey Miscom. Thank you for the post. I am considering this phone. I am wondering if this phone is fully compatible with all LTE At&t bands? I copied the At&t band info from a post on another forum and pasted it below. I assume that it is correct.
At&t LTE Bands
4G HSPA and HSPA+ use 850Mhz(Band 5) and 1900Mhz(Band 2) bands but it all depends on area if they own a license. LTE uses Band 17(700Mhz), Band 5(850Mhz), Band 2(1900Mhz), Band 4(1700/2100Mhz) currently.
It appears that Band 4(1700/2100) is missing from the SM-G906S specs.

You are correct: Band 4 is missing. For AT&T only band 17 is available in the G906S.
Band 17 is the main LTE band for AT&T. I traveled by car a few days ago from Tennessee to New York and except for a few places, I got LTE most of the time. Never saw E, only 3G (AT&T's 4G) and LTE.
Same here I have LTE pretty much 99% everywhere I go. I'm on AT&T as well.
That is good news. Do you guys know if there will be ROM support by cyanogen for this phone?
Also. Where did you guys get yours?

I found this on AT&T official website,
Your device will need to work on one of these GSM network frequencies:
AT&T Multi-band GSM
UMTS, LTE or unlocked Multi-band GSM - 850/1900 MHz
UMTS - 850/1900 MHz
LTE Band 2 - 1900 MHz
LTE Band 4 - 1700 MHz
LTE Band 5 - 800 MHz
LTE Band 17 - 700 MHz
