Tmobile Service - Nokia Lumia 800

Any who currently have this phone with Tmobile USA can confirm to me if it gonna working on their network. As far I knew this phone, it definitely not support the 3G/4G bands from TMO USA, but what if roaming and spectrum agreement with AT&T go through FCC, will I be able to use call with TMO and use 3G service of AT&T if possible?

[Q] A question about AT&T / T-Mobile 4G

Hi, I'm in California and I have an Motorola Atrix with AT&T and I just unlocked my phone because I'm about to switch to T-mobile...
However, my friend told me that AT&T and T-Mobile has different 4G networks. He said the AT&T Atrix can not use 3G or 4G speed on a T-Mobile network, It can only go up to Edge speed.... Is that true? Does anyone know about this?
Hope some people can help me here ...
Thank you

From everything I have read that is correct, but also know that it won't be much longer till you are back as an AT&T customer since they are acquiring T-Mobile.

Its true. While both AT&T and T-Mobile use HSPA+ for their "4G" speeds, they run on different bands. If you want 3G/4G, use a T-Mobile phone. Otherwise, enjoy EDGE. Opera Mini with images set to low will be a big help.
T-Mobile leases cellular space from AT&T which is why unlocked AT&T phones can use T-Mobile service. Not sure if it is the phone's software issue that is causing the 4G/3Gnot working. It's possible that T-mobile implemented their so called 4G first but it's still AT&T equipment.....I work for AT&T. Also 4G, is just higher speed 3G, 4G LTE won't be rolling out until next year.
Thank you for the quick reply... I need to get a T-Mobile phone then.

Yep, but sucks that they still charge minutes when I call a T-Mobile number. I'm switching it for my girlfriend, so I can get Unlimited mobile to mobile minutes... I might get a sensation when I switch to T-Mobile

Good job on the misinformation front.
And also not being helpful, I'm going to assume your in sales and don't actually know anything.
Now on to the OP's question.
T-Mobile uses the same type of technology as AT&T however they operate on different bands. As such most devices that are sold on AT&T will be able work on T-Mobile for phone and edge but don't get 3g or hspa+ due to the radio in the device only supporting some of the bands. Which is why as a general rule AT&T phones such as the iphone, will work on T-Mobile if unlocked but can't use 3g because it doesn't have the ability to operate in the correct MHZ range. Its the same going from T-Mobile to AT&T. My HD2 was awesome, other then the slow data. *Not that my atrix or inspire are much better.
There are exceptions to the rule though. You'll have to check to see which bands the Atrix is capable of using. I know some of the Samsung devices had all the GSM bands so they worked fine on all networks.
the answer is NO the atrix will not work on tmobile USA 3G or 4G network. there, done!

Problem is that if/when the AT&T/T-mobile merger goes through, AT&T will likely flip Tmobile's 3g towers to 4g. All tmobile 3G phones...sorry no more 3g unless you buy a new phone. yay....
linky
AT&T said Monday that it planned to convert T-Mobile's 3G towers to 4G service and move T-Mobile 3G subscribers to AT&T 3G phones.

They won't just flip a switch and everyone has to buy new phones. They will be phased out as people finish contracts and begin new ones. If they don't, they'll be buying T-Mobile customers all new phones or paying fatcat lawyers to defend them from all the lawsuits.

Agreed, sorry I used the term 'flip', never meant to say it would happen instantly . The article I linked stated the switch would take several years. That's not written in stone though, AT&T could move up the timeline if they are losing too many customers to Verizon and Sprint.
This is only an issue if you plan on keeping your tmobile 3g phone for YEARS, which is not likely for anyone that frequents xda .

[Q] What Non-AT&T branded phones work on AT&T's 3G network?

I had read in a thread by azwildcat98 "We know that AT&T uses the 850/1900/2100 MHz US 3G bands, while T-Mobile uses the 1700/2100 MHz US 3G bands, therefore making each carrier's hardware incompatible with the other's 3G network"
I am looking for possibly a list of non-AT&T distributed phones that work on AT&T's 3G network. My reason is that I currently have a T-mobile HTC HD2 connected to AT&T's EDGE network and i am paying $10/month for "non-smartphone internet" (because AT&T and T-Mobile dont exchange their IMEI # database apparently) AT&T thinks i have a crap flip phone... So i dont have to pay $30/month for "smartphone internet." How can i achieve AT&T's 3G speeds while not purchasing an AT&T branded phone so i can continue paying for "non-smartphone internet'?
My problem could be solved by just buying an AT&T branded phone, but im saving $20/month my way.
The only answers I really want to see in this thread are: What non-AT&T branded Android smartphones are out with 850/1900/2100 MHz US 3G bands?

There are a few carriers that use the same bands. None in the US though. The Closest is Canada. Just a warning, the carriers and OEMs to prevent this sort of thing. While they can't tell what phone your using they are starting to be able to tell if its a smartphone or dumbphone.
Please use the Q&A Forum for questions Thanks
Moving to Q&A
I finally found a non AT&T branded phone that has the 850MHz required AT&T 3G frequency! but i dont want that phone, any others?
http://pocketnow.com/hardware-1/how-to-get-an-htc-hd2-with-3g-on-att
Edit: I think i came to the conclusion that any unlocked phone will achieve AT&T 3G speeds if is has 850MHz, and i can get my "dumbphone internet" if the phone is "unbranded" or branded as a carrier other than AT&T.
HTC Sensation z710a (Unbranded) will work with AT&T 4G speeds! gonna try to get one and hope my $10/ month deal holds up... I figure im saving 12months x $20 = $240/ year without "smartphone internet" so i dont care how much i pay for the phone.

Will the verizon m8 work on AT&T?

Hey guys I've been out if the loop, but will the verizon m8 work on AT&T especially with 4G LTE etc? Only reason I ask the verizon iPhone 5s's were unlocked and ATT 4G LTE worked fine on them.

It will work fine on HSPA and AWS LTE but it's lacking band 17 which is still almost exclusively what ATT uses for LTE across the country. The iPhone 5s/5c remains the only Verizon phone that can be legitimately taken to another carrier without any compromises.
I wonder as AT&T continues its rollout of carrier aggregation, if more Verizon phones will get access to AT&Ts networks in carrier aggregated markets.
I guess it all depends on which frequencies AT&T decides to bond, but I'm sure there will be more access to AWS frequencies on AT&Ts networks as carrier aggregation continues to expand.

[Q] Groupon S5 Deal: Work on T-Mobile?

Groupon has a deal for the S5 that says it's for "Verizon and GSM Unlocked":
https://www.groupon.com/deals/gg-samsung-galaxy-s5-smartphones
Is there any way to tell what model # this is? I'm guessing that it is a generic S5 and not the T-Mobile specific SM-G900T. If that's true, then it likely doesn't have the TMo specific LTE frequencies needed for full service (I'm in the Chicago area), correct?
I really hate having to find special versions of GSM devices to make full use of T-Mobile's network...
<TAP><TAP> Is this thing on???
Unlocked for all Verizon and GSM carriers.
On the same page --> https://www.groupon.com/pages/groupon-deal-images-gg-gsm-providers
Only thing is that it probably will not be compatible with WiFi calling features, but I could be wrong.
I know it would work but I was curious about whether it was the same model they sell via T-Mobile that has their unique frequency bands (1900/2100 I believe). Groupon responded to an inquiry and said it was a Verizon model so while I can't confirm it, I'm guessing it doesn't have the extra bands needed to fully make use of T-Mobile's LTE network so it would likely drop down to HPDPA+ in many locations.
According to the reviews, its a Verizon branded phone. A couple of the reviews are from T-mo users and they claimed to have issues with the sim/network not going to LTE, instead it uses their HSPA network.
If it was me, I would not buy this. It is cheap yea, but remember that the S5 is not compatible with the new band 12.
-edit-
The Chicago area isn't getting band 12 anyways, not anytime soon that is.
I'm using a Verizon S5 with a T-mobile rom and it works perfect 4g lte and all If you end up getting it just root it then look at my view forum posts.

LTE problem

Hi need help please , I have a Galaxy S4 I545 , I can anly connect on 3G and even in the back of the device says s4 verizon 4g lte . When I change the LTE network goes without service. Let alone globally connect on 3G, I wonder if I can enable or install 4G LTE bands . Thank you
The SCH-I545 should have 4G enabled automatically. 4G is already installed on the phone unless it has been messed with (ROM,kernel etc.). Is it possible you are just not in a 4G area or have it on your Sim?
Are you located in the States?
The phone is 4G capable, only in USA. Outside, its only 3G. That is how Verizon did it, locking bands so Verizon users cannot have LTE with other providers like T-Mobile or Sprint or ATT. T-Mobile should work worldwide. For Verizon, you will need to unlock bands.
What country are you in ? Most probably, you need band 3 or band 28 which are deactivated.
I'm from Morocco
