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.

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 can only select single specific bands and can't deselect any options? How do I deselect something?

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.

Is there any way to configure the UMTS Band settings on the Trinity / D810? I ask as the ROM provides the following options:
Network Type:
Auto
GSM
WCDMA
GSM/UMTS Band:
Auto
GSM(900+1800)+UMTS(2100)
GSM(1900+850)+UMTS(1900+850)
UMTS(2100+800)
Now ... for the HSDPA Network in Australia for Telstra (Next G), I need the phone to work on the UMTS(850) Band. However, by selecting the option above where the only UMTS(850) is available means that the alternate 3G Band (not HSDPA) of UMTS(2100) is not available, and the GSM Bands in the same selection are not valid for the Australian market.
Couple of queries, and I hope there are ways of configuring the device to achieve this (without getting a new ROM to support it):
When a Band selection is made, what is the order which the device uses the connections? ... i.e. if the selection was GSM(1900+850)+UMTS(1900+850), will it look for UMTS or GSM first? If UMTS, which band - 1900 or 850?
When Auto is selected, I am guessing it uses each option in the list until it finds a valid network? This would mean that for Australia, if left on Auto, you would never select HSDPA for Telstra as it would find the 3G UMTS(2100) network first (non-HSDPA).
My assumptions are that if left on Auto, it looks based on list order (which is the network order in the registry). So, for Australia, I need a setting like the following:
GSM(900+1800)+UMTS(850+2100)
Is it possible to create this Band Selection without a new ROM?

The new Dopod ROM has the same band selections as yours does. I tried changing the selections to manual with bad results. I just leave it on auto now.

I could do that to, but it would mean I don't get HSDPA. I have verified this. The only way to get HSDPA is to set the Band selection to the one with UMTS(850) in it ... this is not ideal, and that's why I posed the question to this forum.
No one??
I am guessing that no one has ever come across this, or needed to do it?
Registry Patch
This Registry patch works for the Hermes. It might work on the Trinity.
[HKEY_LOCAL_MACHINE\SOFTWARE\OEM\PhoneSetting\BandType]
"ItemCount"=dword:00000006
"ItemName1"="Auto"
"ItemName2"="GSM(900+1800)+UMTS(2100)"
"ItemName3"="GSM(1900+850)+UMTS(1900+850)"
"ItemName4"="UMTS(2100+800)"
"ItemName5"="GSM(900+1800)+UMTS(2100+850)"
"ItemName6"="GSM(900+1800)+UMTS(850)"
"ItemValue1"=dword:00000000
"ItemValue2"=dword:00000001
"ItemValue3"=dword:00000002
"ItemValue4"=dword:00000003

"ItemValue6"=dword:00000005
[HKEY_LOCAL_MACHINE\SOFTWARE\OEM\UMTS\BandSelection]
"Band"=dword:00000005
You really just need to add ItemName5 and 6, and ItemValue5 and 6, and change the ItemCount from 4 to 6 (as you added two options) using your favorite Registry Editor.
Do a soft reboot of the phone. Now you can select the NextG option GSM(900+1800)+UMTS(850)
3G connection
I drive around the Perth Metro area a lot for work and am finding that if left on Auto the connection is lost quite often mid call. How have you found the 810's management of the bands? And the auto fallback? Is there a way to set the fallback threshold so it drops back if under 2 bar signal strength? At the moment it sits on 1 bar strength and drops out mid call.
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).

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.
is it possible to change frequency settings so i can use this phone to get 3G and 4G in the US.
Thank in advance
Try this...

Did you try select WCDMA 1900 option into BAND SELECTION menu? To do this just dial *#197328640# and then select UMTS -> Debug Screen -> Phone Control -> Network Control -> Band Selection -> WCDMA 1900. But if does not show WCDMA 1900 on the list, you should really let it go...
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?

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?

Unfortunately the AT&T s6 doesn't have support for WCDMA 900 however GSM 900 is supported. You would have to put your phone is GSM only mode in order to get that. For GSM only mode, in your dialer type *#*#4636#*#* > Device information > There should be a menu that says select preferred network type, select GSM only. This will be much slower than WCDMA but you will have a better signal.
