Flashed my galaxy tab with CM9 and it is running great so far. Had SIM unlocked it long ago. Originally got it from AT&T, now on TMo Network I am getting barely Edge...on AT&T it says 3G/H and gives around 2MBPS...anyway to get it to give better throughput on Tmobile network? From what I read, there seem to be differences at the hardware level and just flashing a Tmobile modem wont help??

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).
I'm thinking about picking up a used Note 3 to use on my AT&T account. Is there any reason to get an AT&T branded note over T-Mobile branded?
I can SIM unlock the T-Mobile, but would have to deal with locked bootloaders with AT&T. All the supported bands are there using the T-Mobile on AT&T, right?

I used the T-Mobile Note 3 for a while. I unlocked it using Chanfire's app. When using my AT&T sim card in it, I found the LTE to be horrible, despite supporting band 17 (700mhz) In places where I had average LTE on the iPhone, the TMO N3 would be on H+ or have the worst LTE signal. This was frustrating. I took it back. It was fun to flash roms and kernels though.
I got an awesome deal on a new AT&T note 3 where I couldn't pass it up haha. At first I noticed my AT&T LTE signal was not as good as it should be. I then created a thread about it. I cleared the cache in my phone and did a full factory reset. Now my LTE seems fine. Constantly sitting on -93db on my desk where my iPhone gets the same.
I'm pretty happy now with my AT&T Note 3. Rooting was so easy and gives me everything a custom rom would.
Yep, the LTE (band 17) on my N900T is horrible. My neighbor has N900A and we compared them side by side (with punching *#0011# and monitoring signal on both devices) and my N900T was always showing signal that was ~15db lower than the N900A. Gonna sell it. Will wait for Xperia Z2.
I agree completely with Matt and bormasina.
I just sold my N900T and bought a N900A and have noticed a dramatic improving, specifically in LTE bandwidth.
Hands down, the AT&T version performs better on an AT&T network. Go figure.

Yeah. Is it a coincidence that the ATT version perms better on the network it designed for? I'm sure ATT optimizes their signals in their phones for the proper frequencies.
I'm actually sitting in a place where my N900T would sit on a -105dbm signal and right now my N900A has been locked on a solid -89dbm. Night and day difference.
Go with the At&T version. The T-Mobile version is fine though if your on their network. But AWS still does suck in general when it comes to signal strength.

Anyone else running a Tmobile Note 3 on the AT&T network? Is there any difference in reception or LTE? I've seen in other threads people complain that they dropped calls and had less reception with the Tmobile hardware on ATT, I'd be curious to see DB measurements and not simply rely on the reception bars. Also heard complaints that the Tmobile N3 doesn't hand onto ATT LTE signals well.
Also using the Tmobile Note 3 on the ATT network does;
1) does tethering still work?
2) does it work with an AT&T microcell?

you should be fine.. the main thing is to make sure you set up the att apn. i haven't seen or heard of any of those issues.. the hardware should be fine.

Hey what's up guys I'm using a 64 gig unlocked AT&T S6 edge on the T-mobile network. I'm having the troubles of only getting 2g connection at best. I been on the phone with T-Mobile and AT&T to figure out why I get such slow speeds. My APN is correct, but the network settings won't let me select LTE/WCDMA/GSM on my phone. AT&T tech support told me to come to this forum and upload T-mobile firmware to the phone so it will pick up the frequencies I need to hit 4g speeds etc. on the T-mobile network. Has anyone had to do this before? If that is what I have to do does anyone have instructions on how to do it and where to get the firmware I need? Thank you!
I see people asking about flashing their AT&T and TMobile phones to Verizon, but I'm wanting to do the opposite.
I have a sim unlocked S8+ and I recently switched to Cricket who uses the AT&T towers. So I thought it was possible if I flashed the AT&T firmware I would get better reception unless the phones for the different carriers lack the radio capacity but my wife's Pixel switched and gets 4G everywhere. I get 4G in town and it switches to H or H+ when I'm in smaller towns and it doesn't matter which preferred network I have it set to or global mode.
It is the Verizon model though, so I don't know if the boot loader being locked would prevent a different firmware flash from ODIN. I've had plenty of experience with the program from rooting my S7 Edge, S5, and S6. Just the 8 has been a tough nut to crack it seems.
