Oh NOs! But I'm kinda confused at this 850 and 1900 AT&T thing. Will the phones hardware just be like "Nah, son. Too much bandwidth."

"yes I said that already, can you transfer me to tech support" "oh let me transfer you to customer service." "yes that'd be great. thanks" "i'd like to personally thank you for calling AT&T. did you have any questions today?" yes. how are you employed? CS Reps unavailable this late in the day.
Damn. Oh well.. I use T-Mobile anyway... so I didn't expect fast or good or stable or acceptable coverage of any kind.

my S730 is due to come today..I guess it will be going back....why did they make a device with no 3G connectivity in USA?.....mobileplanet is going to get a lot of returns!

Because it's not a device for the U.S.

No US 3G or GPS on S730
I spoke to On The Go Solutions prior to ordering the "US released" S730 product and they stated that 1900Mz UMTS is supported by the unit and cautioned me that one must be utilizing AT&T's network to use the feature.
I ordered the unit only to find the statement is incorrect - only 2100Mz is supported; thus no US UMTS support.
On The Go Solutions has offered to take back the unit.
I note that the ambiguous "UMTS supported" statements on several US vendor web sites have been changed to unambiguous "2100Mz-only UMTS supported" statements.
Whereas there is NMEA GPS data on comm 4 (8 bit, 4800 baud), the data does not appear to contain any useful information. No actual satellite data is provided, even though I have left the unit outside, with an unobstructed view of the sky, for over an hour.

S730 Gets FCC clearance
http://www.smartphonethoughts.com/n...n-of-the-htc-s730-gets-the-fcc-clearance.html
S730 received FCC clearance for the US. I wonder if this helps us.

Yeah, saw that. This is model WING200, mine is model WING220. Wonder what the difference in hardware is.

WINGS220 is the modelID for single band WINGS. Maybe the diversification is only done by software configuration (e.g. NV items). See my thread on Radio ROM dump where I explain how to dump NV items. Someone should compare them.

3g wont work in the states, even on ATT. I see mine try from time to time but it always ends up back on Edge. T mobile is rumord to be working on a 2100 band 3g network but no real word on it yet.
I would love 3g but I dont really miss it either. Edge is fast enough and I am a heavy data user, I only notice issues when its trying to reformat a website that was not made very well.

Okay this may come as a dumb question. I have T Mobile and this phone has the Bands such as 850 and 1900 so will this phone work in the states?

Negative, theres speculation in other threads that depending on the chip version in the phone it can be unlocked through software tweeks but at the moment it is just speculation so it will not work in the states.
If the American version releases you bet that will work on 3g. As of now our phones use the 50, 900, 1800, 1900 for voice communication and GPRS / EDge while using 2100 for 3g. T-Mobile has been working on deploying a 2100 band 3g network so it is possible that it might work on your phone eventually in one of their markets.
But as of now unless your in an area where they have it set up, or we figure out what the chip is and see if changing one of the settings wil enable these 3g frequencies for the states its a no go

Okay so i have done some research and from what i have read the phone will work in the states utilizing GPRS/EDGE. I have read Forums with people who live in the states and have this phone. Now the one thing is that you wont be able to use the 3G stuff which is fine by me because I currently have a Excalibur which doesnt have it anyways. I am still a lil confused because i get all this different information from people saying that you wont be able to use the phone and others that say you will. Someone help clear this up for me please !!!!

yes, you can use the phone in the US. i am using it here in San Diego, CA. You just wont get 3G data speeds, only Edge

I've had the S730 sense Dec. 07 and use with AT&T, no 3G but it works great. I'm more then pleased and I live in the Carolina's.

[Q] is there a possible way to change the frequency??

I am living in Canada, and all galaxy tab available in this country is P1000 which has the frequency band of HSDPA 900 / 1900 / 2100.
But I am in Mobilicity which uses AWS(1700/2100) network like T-Mobile. Therefore, I can't use galaxy tab with my provider.
Is there any possible way I can change the frequency of galaxy tab P1000 to 1700 / 2100 ???
Please~~ anybody has an idea? if it is a software issue, at least I can try~
p.s
if it is impossible, anyone knows a shopping website sells a used t-mobile galaxy tab with shipping at Canada???

I have a very similar issue. I bought a T-mobile tab in California with the promise that it would work in Mexico. What that promise was the truth it wasn't the whole truth.
Mexico's 3g system is in a frequency of 850/1900 mhz. The T-Mobile device is on 1700 mhz. I realize that frequencies are a function of physical antenna length but they can also be tuned (as a radio receiver) which is what a cell phone really is.
Is there a way to tune the receiver part to correctly function on a different frequency?

You two should trade tabs.
T-mobile uses 2100/1700 aws and cannot be changed to other data frequencies. So the best you get is EDGE.
Also, T-mobile tabs have to use both frequencies, so they don't get 3g in places that use only 2100.
At&t uses 1900/850 and cannot be changed either. There are tabs that use 1900/900.
The only quad band tab is the unlocked no carrier version.

I use an at&t tab in Mexico with a Telcel sim card and get 3g. When I used a t-mobile tab, I only got EDGE with both aTelcel and a Movistar sim card.

Thank you for your response. In my case I cheaped out and bought T-mobile due to its price and the promise of receiving an unlock code. I was ignorant of the frequency issue until now...too late.
So now another question arrises. Since these devices are basically radios, wouldn't it be possible to write a piece of software that is essentially an antena tuner? Remembering my boyhood electonics (ham studies) it seems to me that any size radio antena can be "tuned" to the correct frequency with the right equipment. Or perhaps an after market hardware that utilizes the USB input port?
Just "spitballing" here but it seems to be an idea worth some money considering all of us who want more out of our devices. Any thoughts?

Yeah, buy the device with the right hardware for your carrier.
It's a hardware limitation. No piece of software will ever be capable of fixing it on earth. The hardware is not physically capable of those frequencies.

These devices are digital. When you went to school the radio technology was analog, and you could tune anntenas, but with digital, the wave is fixed only to the built in values, so no tuning possible.
Trading is easier.

@gspajon:
I use a Telcel Amigo sim in a t-mobile tab and a month to month data plan, 3 gigs of data and unlimited voice, for $30, and I can pay the bill through a website, or at any OXXO. The Telcel EDGE is pretty fast for surfing and navigating, and sending/receiving attachments. I can live with it.

Hey ranger I have the same deal and I too am able to find the edge network. However here in Progreso, Yucatan it is painfully slow. I'm sure that is a result of my distance from the main provider signal in Mérida. I am able to access the net and surf at speeds closed to dial-up. It's frustrating considering my tab is capable of so much more.
Botom line is I thought I hade reasearched this BEFORE I bought. The frequency issue never came up untill now...AFTER I spent the money. Oh well...my wife has an iPhone that I bought her here and I can link in to her with the router capability and my tab's wifi.
Thank you for your kind assistance...where in Mexico do you travel? You are welcome to visit here anytime...my house ison the beach and the weather here is almost always lovely.

So what happens when we flash different modems? I thought that changes the supported frequencies?

Many people wish this was true, but the at&t tab has a different radio from t-mobile, and no modem can change that.

It is too bad about the tabs. I mistakenly bought a t-mobile tab too. I use it as a wifi tab most of the time.
I am a teacher in the US, but weekends and summers I am in Tijuana-Tecate building homes for poor families. We give away 250 homes a year, God willing.
My partner in Mexico grew up in the Yucatan - it is my wish to visit there some day!

Two homes student from my school built last month.

There is hope
I recently found a new device that allows me to use my tab here in mexico as is. This solution may not work for every one but it is working great for me. I recently purchased a mobile wifi router that works on Mexico's 3g system. Its the Huawei E5.
Its about the size of a small cell phone and I can connect to it using wifi. It is portable so I can just put it in my pocket and off I go. Now I didn't have to worry with unlocking the tab. I just leave the original T-Mobile chip in and use wifi here in Mexico.
I am quite certain this little device is available in Canada as well. That way you (I) can move freey between two nations without the "blah-blah" of this system vs that one and how I "should've bought" differently.
The cost was reasonable and I have stll paid less than an iPad. Not to mention I can also use my laptop here the same way as in the US. The service is very reasonable and is actually less costly than t-moble.

Sprint iDen 800mhz -> Sprint CDMA/LTE 800mhz and the One

So, according to HTC.com and Phonescoop.com, the radio for the Sprint version will have 1900mhz LTE, just as with the HTC Evo 4G LTE. Sprint is supposedly rolling out 800mhz LTE (former Nextel iDen) in the 2nd half of 2013. Question is, can the radio be modified via software to have 800mhz LTE, or is this a hardware issue?
Anyone know?
Thanks!

What a mess most of their customers will have, IMO stupid decision. Most people to use this network will need to replace their phones, and it means for you, that you have a decision to make on your LTE future, one which phone you buy or change provider, second option probably the best.
Please note that the Snapdragon 600 chipset does not have any modem support on chip, therefore additional hardware radios are added per requirement. HTC should have gone for the Snapdragon 800 which has a modem that supports LTE as well.
And in short, no you can't just change, it is hardware. However, towards the end of the year hopefully all phones will start to use the Qualcomm chipset announced yesterday which covers all bands worldwide.
HSPA/WCDMA:
Europe/Asia: 850/900/1900/2100 MHz
GSM/GPRS/EDGE:
850/900/1800/1900 MHz
LTE:
EU: 800/1800/2600 MHz
US (AT&T): 700/850/AWS/1900 MHz
US (TMO): 700/AWS MHz
US (Sprint): 1900 MHz
Asia: 1800/2600 Mhz

Re: Sprint iDen 800mhz -> Sprint CDMA/LTE 800mhz and the One
Ok thanks for the clarification that's what I was thinking. Perhaps Sprint will go ahead and pre-load the LTE radio for the former iDen 850 spectrum, and activate it with a firmware update. That's all I can hope for I guess.

Very interesting. Not sure what is going on, also not sure if HTC has any clue what is going on. There website is obviously wrong or not up to date. Still doesn't list 800MHz in US.

Looks like the One will only have Sprint band 25 LTE (1900). At least from the FCC figures.

SVDO is also missing, so no simultaneous 3G and voice. Understandably, though, with the LTE network increase.

Have gone from S1 to S2 with sprint, might go with HTC One instead of S4.
Does only one band of LTE on the phone mean there could be some towers that use the band not included in the phone, so I would only get 3g?

Do you have problems with Sprint now? are you using LTE currently?
Your LTE coverage will only be as good as how many 1900Mhz towers Sprint has around. If sprint doesn't have a tower in your phones range for LTE then you will only get 3G
If you travel a lot with roaming, then you will most likely want the AT&T model which covers most of greater America. If you get LTE while roaming will depend on Sprint and other Carriers agreements, otherwise yes your option will be 3G.

Thanks, I wasn't sure if their towers would have both bands or just 1, I wasn't sure why the phone only having 1900Mhz would matter.
I don't have an LTE phone, but I do have wimax coverage in Daytona, LTE is supposedly on the way. My work forces me to travel a lot, don't get to use 4g much anyway, I'm heavily dependent on roamcontrol, with a hacked PRL I make due with us cellular's 3g usually. When I am in Houston/Daytona I would like my LTE phone to have proper coverage though ;P

LTE coverage is great throughout Houston. It gets weak and sometimes drops to 3G when in buildings though.

Yes you are thinking correctly, however Sprint's 1900mhz is pretty comprehensive, in fact, I believe Sprint has more 1900mhz spectrum than any other carrier (hence why Sprint used to be 'Sprint PCS', referencing the PCS 1900mhz band), and far more 1900mhz spectrum than the old iDen 800mhz. You should not have any problems whatsoever.

Ill just be glad when they roll out 800mhz 3g..which this phone does have suport for. If they finally get around to upgrading the 3g here in Houston then I wont mind as much when the connection drops down. As such, the way it is right now, 3g is nigh on unusable, and sometimes so is 4g.

It has nothing to do with the modem. The One has a separate Qualcomm MDM9x15 modem which is not that much different than the modem that's integrated into the Snapdragon 800. It has plenty of ports which could handle another LTE band if one could be "fed" to it.
The issue is the front end RF stuff. Due to the uniqueness of the 800MHz LTE band that will be used by Sprint, it's difficult at this point to source the necessary antenna switches and transceivers and other front end RF components that will handle that specific 800Mhz LTE band.
My guess is that you won't see any ESMR800 LTE phones come out before Q3 or Q4 and it's also probably at least six months at this point before Sprint starts to deploy the technology commercially.

They are not going to roll-out EVDO on 800 MHz, only voice/1x, and a 5x5 LTE carrier.

That is not what I have heard from multiple Sprint reps about EVDO on the 800mhz. I was told, very recently in fact, that the voice/EVDO would be rolled out to the 800mhz, well before any LTE bands were activated in that spectrum. That Sprint was pushing for better penetration for voice and EVDO signals through the 800mhz spread, and that LTE would be focused on the 1900mhz for the time being.

According to this article:
http://www.lightreading.com/sprint/sprint-to-dial-800-for-lte-in-q4/240153521
"We expect to deploy LTE on 800MHz in the fourth quarter," said Steve Elfman, president of network operations and wholesale at Sprint on the call.
Nonetheless, Sprint is clearing the way for LTE integration with WiMax partner Clearwire. Hesse said he expects Clearwire's fast 4G service to start arriving late in the third quarter with "TD-LTE, multi-band devices."
With so many different chunks of frequency to support, Sprint will need these devices to switch between 2.5GHz, 800MHz and 1900MHz to get around the network.

That's not that unusual and really not that big of a deal for the the radios to handle in the upcoming devices.
In any case, working with multiple bands is fairly commonplace. Look at Verizon and AT&T for example which operate four different bands.

Wow
This has to be the most technical thread I have ever read Where do you folks obtain all this knowledge?

Verizon LG G2 on T-Mobile 4G LTE...

Been playing with This for a few days... There's a thread in the Verizon G2 for running a T-Mobile rom on the Verizon variant of the G2. I live in an area where the T-Mobile towers were refarmed for LTE. Well I've been running the Rom And ordinarily I was getting their HSPA+ "4G". Not realising I could Go in and change the connection types or whatever, I changed it to GSM/WCDMA/LTE and this happened:

U can buy it CHEAP if u know where to looking.
Has built in wireless charging for those who like that.
And it can operate on 2 4G LTE networks.

Not yet, looking at family plans and coverage plus employee discount which could sway staying or going. Also have contract till June on unlim which deciding if I want to keep or not.

I'm on month to month with Verizon right now and still have unlimited data. I priced or tmo as I thought of changing to save money... I have a 20% vzw discount through work so monthly costs were identical. I stuck with Verizon.

My main job doesn't offer T-Mobile discounts or Verizon, but my 2nd one does. 17%. Even with the discount not utilized from T-Mobile, it ended up being $30 cheaper for me on a family plan with my wife. Add the 17% and it becomes even cheaper. But their service isn't great at my house. And we can't get internet at my house because of the way the street is wired around my way (sucks but oh well) so we use a VZW hotspot. Idk what I should do yet.

How Do I Install T-Mobile
Reason I'm making this post:
As stated in the thread, the VZW G2 looks better than others.
U can buy it CHEAP if u know where to looking.
Has built in wireless charging for those who like that.
And it can operate on 2 4G LTE networks.
Just posting this for us verizon users who are sick of paying these outrageous cell phone bills and are looking to try out other providers.

I am still trying to get mine working on the T-Mobile LTE. Am told I have to root, but how do you get around the phone staying on "Connected As Installer" for only 30 seconds, then for no apparent reason, swapping to MTP mode? Also, I would like to see step-by-step instructions on how to root, then install the T-Mobile rom.

Bought mine on Saturday and running PA. Got the $45 plan but only 500 mb. Might jump back to T-Mobile next cycle is it's 4G is guaranteed. If not, dihb up automatic payment and get an additional 500 mb.

Verizon 26A stock rom running on Tmobile with LTE
I have my VS980 working perfect on T-Mobile's network through Straight Talk getting LTE on the stock rom that came with the phone. The only "issue" is when I reboot the phone it loads 4G lte in cdma mode until I make my first call, but even then I am still able to use the internet on 4G lte in cdma mode. All it takes is one call made and it automatically changes over to GSM 4G LTE. I have since rooted, but I originally was running on Straight Talk's T-Mobile sim without root. I dont get the VoLTE I had been getting through Verizon, so when I make a call I see the 4G LTE icon change to either 3G or H (hspa+), but it reverts right back to 4G LTE within 5 seconds (usually less). I did install a modified apk for the Verizon Hotspot which now lets me use hotspot and tethering, after I am notifed that a Verizon LTE sim is not installed which is required for Hotspot to work. I am lookind at full bars right now ans I can send a screenshot if needed. I dont think I will flash to a T-Mobile rom since everything runs so smoothly just the way it is. I am in Kansas City, Missouri, and have traveled all over Kansas City Missouri and Kansas City, Kansas ans all the outlying suburbs abd LTE is flawless. When I get too far from the metropolitan area I will end up with umts, G, E (edge), but I never lose the ability to make or receive voice calls, just 4G LTE.

VS9800 on Straight Talk's T-Mobile LTE with stock rom
Sorry, I failed to mention that I actually access T-mobile's 4G LTE network through a Straight Talk sim. All I had to do was replace the Verizon sim with the T-mobile micro sim that came in the Straight Talk BYOP kit ($60-that included 30 days of unlimited service and 3 gigabytes of 4G LTE data) & the phone was instantly operating on T-mobile's 4G LTE network sans any apn configuring whatsoever. Kept the phone on Global network mode. Kansas City is a refarmed area for T-mobile. I suspect I am getting their 4G LTE on the band 4 (aws) spectrum. I have done quite a few speed tests and I get around 30 Mbps for upload and download when I have 3 or more bars. On Verizon in Kansas City I was getting 70 Mbps with full bars, so. I definitely took a hit there, but the difference is mostly academic, really.

Poor reception: Note 4 falls to 3g 900 (1mbit) while S3 LTE has stable 4G 1800! :(

Hey,
just received my european snapdragon 910F and it instantly updated itself to a ANJ4.
i'm a happy user of a Galaxy S3 LTE that really brought me 4g everywhere.
well, now i use both i9305 and 910F, and there's a major issue with reception.
in the bedroom, which is inside of a concrete building, S3 LTE shows 4G 1800 at -106...-110db (*#0011#).
Sometimes even -115db y no pasa nada - it holds on to the frequency and provides stable 4g.
Not blazing fast, but at least 8mbit DL, allowing for acceptable browsing and apps usage.
Note 4 goes straight to the 3G 900 with miserable 1mbit DL, 0.02 UL (forget VoIP), increased ping... it's a pain!
luckily, i have a multisim, so both phones work on the same network with the same plan and at the same time, so the problem is evident.
when i bought S3 LTE, it showed significantly lower signal (difference of 10-15db) than my Motorola o Sony phones, but Note 4 takes it to the whole new level.
anyone tried modems from other regions? p.s. you can update a modem via odin without affecting knox byte, right?
I don't see the modems thread started yet.
for S3 LTE, modems from France, Germany, Norway and Russia (Megafon XXUFNI3) showed best results. I use the latter.
HELP!!!

Interestingly my Note 4 gets 4G reception where the Note 3 does not! I had both side by side in a marginal 4G signal area, on 1800MHz (Three), and the Note 3 refused to stay on 4G even if I tried to choose the network manually...it would go to 4G for 30 seconds and jump back to 3G. But on the Note 4 it holds the 4G signal!
So my experience suggests the opposite of yours....I then checked the dB level on 3G (as I can't get the Note 3 to stay on 4G) and they were both pretty much identical, which may simply suggest that the Note 4 has a different algorithm for network switching.

what region are you, and what is your current modem?
i'm FVF España (or XXU), with XXU1ANJ4 (modem is CP from *#1234#, right?)
forgot to mention that i also have Galaxy Tab S 8.4 T705 tablet (which is, in fact, a supersized Galaxy S5), and it sticks to 4G in the same room too. I didn't have the opportunity to try Note 3, so can't compare. but googling "poor galaxy note reception" shows so many horror stories it's just mind blowing.
so i'm willing to try a different modem.
what is worse, at least with S3 LTE i could lock it to 4G only via Band Mode (@ service menu), but on recent samsung devices that is no longer possible

I am in the UK, with U1ANJ4 modem as well! So this is a bit surprising that you have this difference. I don't think any of the Note phones have had the "best" signal reception to be honest. I have a really old Nokia Symbian phone (you remember the ones where the screen and keypad slide up and down?) with 3G...and it can get 3G reception where my S3, Note 3 and Note 4 cannot get anything.

When it is actually on 4G 1800 in the same room, it shows 8 to 20Mbit DL and 3 UL with no problem.
i'll keep watching it to see if it is a temporary network issue, as they've been rolling out carrier aggregation here and i don't see it working yet, and VoLTE is still to be enabled.
Hopefullly LTE800 will ease the pain, but we will (maybe) have it here starting january.

i'm also having even bigger issues with Wi-fi.
my wi-fi connection is capped at 5.3MB download! (although link speed is from 108 through 180 mbps N draft).
And i'm not the only one!

In 4G the reception is very good and 4G is stable. But in H+ the data reception is unexepectable! 3G is very very low! So same or that phone. My phone is from Greece and in ANG4 rom

All samsungs I owned have worst reception than other phones.

+1000.
it smells sort of planned obsolescence but in a way that there should not be a perfect phone because otherwise all other phones will not be purchased.

My 4g and 4g+ speeds in london are amazing! I've just got 95mb down on 4g+. In ee with a uk 910

Okay, good news:
Thatks to the super useful post describing how to enter the Service Mode and Band Info , i've managed to lock my N910F to LTE-only.
for this, i had to manually disable each and every 2G and 3G frequency.
apparently there's now no easy way to select just a group of band modes, or cancel it easily. have to turn on/off over 10 frequencies.
well, better than nothing!
when N910F fell into 3G again, i locked it to LTE only - y voila - no problem at all. works great as S3 LTE did.
websites load fast; speedtest shows avg. 10DL/3UL with -112...-117dB.
the downside is that voice calls do not work as network doesn't have VoLTE yet.
So it's definetely not an antenna issue, but
either 1) modem settings which is too cautious and has a different threshold to fall to 3G to guarantee voice availability;
or 2) network sees more dropped packets and says to go to 3G.
I have also noticed that if i position the phone in landscape mode AND hold it with hands, this affects reception.
for example, doing it during speedtest in that room with poor signal, decreases download speed from 10Mbit to 3Mbit.
these are all frequences that were enabled by default:
anyone knows what RF support mode is?
