I bought a Nexus one that was only compatible for T-mobile's 3g, but is there anyway i can change the 3G band so that it will run on At&t's 3g?
NO....its hardware enabled for only T-Mobile's 3G bands....AT&T has a totally different model and band....my friend...YOU'RE definitely EDGE!!

I tried to get TMobile service for my Nexus one but it wouldn't pick up 3G. So I called Google tech support and they said my Nexus one is an AT&T only nexus one. What's up with that? I thought this was an unlocked phone able to handle any GSM carrier? Can I get it to work on TMobile?

maybe they meant AT&T 3G, it should pickup the EDGE network on Tmo or you are in a dead zone.

it will work on tmobiles edge service, but not on 3G. tmobile and att have different frequencies for their 3G signals. and yes, there are 2 kinds of nexus ones. one for tmobiles frequency, and one for atts frequency.
If I root the phone will I be able to use it on tmobile?
No, Tmobile runs 3G through 1700mhz band & ATT runs 3G through 850mhz & 1900mhz bands. Both carriers use 850/1900mhz bands for gprs & edge network. There is no way to change the frequencies your phone uses because its a hardware issue. This has been attempted many many times with the US always getting phones last.
This is something to determine when first buying the phone. Did t-mobile sell you the wrong version of the nexus?

There is a difference between "unlocked", meaning - any SIM can go in and the phone won't stop it from working, and "correct band for GSM/3G", which is in hardware - the phone has support for X different frequencies of GSM and Y different frequencies of UMTS (3G), and if the carrier you're trying to connect to doesn't work with any of those frequencies and works with some other ones - having a working SIM won't help you, since the phone won't find the working frequencies.
And this question was answered about 10000 times.
I have a US T-mobile Galaxy Tab which was officially unlocked by T-Mobile.
I took a data plan with ATT, but I am only getting Edge, no 3G
Doing some research I read that T-Mobile uses a different 3G than ATT therefore the issue I guess.
My question: Is there a way to configure the T-Mobile Tab so that it can Connect to ATT 3G or is there a Hardware impossibility?
Apreciate the help

Hardware limited, unfortunately. T-Mobile uses 1700mhz, whereas AT&T uses 850mhz and 1900mhz for 3G

Thanks, its a bummer as their data plans are more interesting for me ...
May be if they merge they will straighten things out in the plans. One can dream
Look in the dev section, rotohammer has a modem switcher, which gives 2G+voice or just 3G alone.
There is a bounty searching for a cook to work on the modem.bin for us, but no takers.
Look at the Dev section or get an ATT Mobile Hotspot and share the conection thru wi-fi to the tab, the only bad side of doing that is that you can't use Gps navegation
Thanks all.
Dont realy want to go the custom rom yet as I may not keep the tab (waiting for newer models).
So I'll see how good or bad it is on ATT Edge, and switch to Tmobile 3G if it is really bad.

I thought that the SGT used software defined radio (baseband) for it's cellular modem and therefor isn't it possible to flash the at&t modem.bin onto the SGT and take advantage of at&t's 3g services (with the appropriate frequencies)?

nope, which is why I thought the AT&T Gtab to be the most desireable, as it can do AT&T 3G plans, but also take advantage of Tmo's $1.49/day DayPass (EDGE only). The Tmo Gtab cannot use the DayPass (Tmo has locked it out).
Hi everyone i tried searching but didn't come up with anything. I'm considering purchasing an unlocked nexus one on amazon and I'm not sure if its a tmobile or att version I have tmobile as my provider if i were to get an att version would i still get 3g access? I know if it was the opposite i there would be no access for 3g on att.
Thanks
I believe t-mobile's 3g is 2100mhz, which means the atnt one should work on the network.
I'd get a second opinion though, I'm more knowledgeable on Australian networks than US ones.
Ok thank you for the input, if anyone could confirm this that would b great.
The devices are completely independent of one another in regards to 3G. Cross network compatability only extends to Edge services.
Someone jump in and correct me if I am wrong, but I believe that T-Mobile 3G requires both the 1900 and 2100 frequencies to work (up & down link).
Rod3 is correct the at&t version will not work on t-mo and the t-mo version will not work on at&t, in respect to the 3G that is you will still get edge either way.
Although as far as the both 1900MHz and 2100MHz I'm not sure about that but it's possible, anyone care to add some info.
EDIT: Just Googled it and it's 1900MHz for 2G and 1700MHz/2100MHz for 3G encase anyone is interested.
Dude, thanks for the correction. I knew there were 2 frequencies for 3G and I just picked one off the top of my head. Now that I think about it, yeah 850 and 1900 were for 2G.
Has anyone tried to take a T-Mobile N1 on VZW LTE? While I'm not quite sure this is possible given that LTE runs on 700mhz which isn't supported by the N1, it does appear 3G runs on 1700mhz, which is supported. I've had it with T-Mobile in Denver and am looking at other options while I wait for the first ICS phone. Thanks!
T-mobile and Verizon use different technologies to implement cellular coverage. A T-mobile phone will not work on the Verizon network.
I'm only getting EDGE connection /speeds from t-mobile. However according to a press release a couple months back, my area was supported (goleta/Santa Barbara area) for HSPA+). How can I enable this network or why am I only getting edge? I am using a Criskelo rom.
Correct me if I am wrong but international note can ONLY be used at edge with US T-Mobile. The note doesn't have the radios for the Baseband of T-Mobile frequencies. As I have read in the forums in the past only at at&t can connect the note for 3g, not 100% sure for the last.

if you are on GSM network .. switch to WCDMA only network in your network settings
3G/4G of T-Mobile USA uses a relatively rare frequency 1700/2100 UMTS Band IV (aka AWS). The Note can't support it. You choice is either stick at the EDGE speed or switch to AT&T(or its MVNO).
TMOUS is starting to refarm their 3G/4G frequency to which the Note will support. But I think it might takes years to get the work done.

tmous is rolling out 1900 frequencies so it will be able to get 3g and possibly 4g depending on where you are... currently there are members on here from the northwest that have confirmed this working...
as for the question at hand i would contact tmo and ask if the towers are running and where in your area to make sure... the auto gsm/wcdma mode should work fine because if you leave the area where there is 1900 and are on wcdma only you will get no svc...
Well here's the press release: newsroom.t-mobile.com/articles/new-4g-markets-nov2011
Hmm...I'm a total noob at this stuff and guess I was assuming I was gonna get HSPA+ due to it listing 1900 mhz in Santa Barbara on the Wirelessadvisor website in a zipcode search.
Am I wrong to assume that if the network is 1900 mhz band? Changing the gsm/wcdma didn't do anything. Guess I should contact t-mobile to make sure?
