How compatible is the atrix with T-Mobile?

Sorry if this has been answered but I'm on the xda app and can't search. I'm thinking about getting this phone and unlocking it to work on T-Mobiles network. How cross compatible is it? Will it work with the T-Mobile "4G"?

Nope, you will only get 2G (EDGE).

t-mobile and at&t use different 3G frequencies, so if you unlock it you will only get EDGE speeds. Not worthy IMO, you have lots of options in your country, i would recommend to wait for the samsung galaxy s II phone.

Will work on the network but data will be at Edge speeds, not 4G.

On the new Nexus S - if you run out of internal storage - what size memory card can you add? Oh, wait they left off the SD card slot on that model. But those super AMOLED screens are really easy on the battery right? Oh wait, if the screen is black they use less juice but not otherwise.
Sorry, had to pick on you. Suffered with the captivate for 8 months..... yeah i drank the Koolaid - now i know better - but samsung sure can spin it.

Just ignore him, hes been trolling all over the Atrix forums. The gyroscope in his phone apparently makes his keyboard so fast that he cant use punctuation.

Unfortunately NOT ...
Inspite every where they said you'll only get EDGE , I Saw one guy saying he got 4G on simple mobile which uses the TMO towers sometimes (both have same frequencies)!!!
I bought the ATRIX on TMO and for 2 days now only EDGE

nowhere do they say you can use an att phone on t mobile 3G. it's been known for years that their frequencies are different and incompatible. you just didn't do your homework before purchasing.

I knew 99% it won't work but i took the challenge anyway ..

That code process is to unlock the phone to enable it to be used with networks other than AT&T. But that doesn't get you data speed any faster than 2G/Edge using an Atrix on T-Mobile's network.

I'm a little confused here. You guys are saying that the Atrix will only get 2G/EDGE speeds on TMobile because the frequencies are different.
I am currently using the Nexus One.. how is it that I'm getting 3G speeds with a phone that is compatible with both AT&T and TMobile then??
Doesnt this mean that the Atrix should be able to get 3G speeds as long as it has the appropriate software? or am I not understanding something..

There are 2 kinds of nexus ones.. one with AWS bands (tmobile) and one with the regular 850/1900 (ATT). That's why you see them work on both tmobile and att. But a single device won't work on both bands.
It is a hardware issue. No software flashing will be able to fix it. If you bought the wrong one then you're stuck with it.

False. There's not a chance in the world that is true. T-Mo USA and AT&T use mutually exclusive bands. No carrier-branded phones carry both bands. The only modern phone that carries bands necessary for 3/4G on either network would be the upcoming, not-for-sale/developer-only Nokia N950.

The Nokia N8 and E7 also have the 3G frequencies necessary for both At&t and T-mobile, as well as Europe/Asia (850/900/1700/1900/2100). However, I agree with you that no At&t/T-mobile branded device carries all the needed bands.

Vibrant can be used on T-Mo and AT&T as well

Ah, I see. I didnt realize that there are 2 types of the Nexus One.
I had assumed that since they are not branded by any carriers that they were all the same device.
Thanks
I was really hoping to have my TZones internet plan, which runs at 3G speeds on the Nexus, run on an unlocked Atrix but that doesn't look possible.
Are there any phones newer than the Nexus One that will work with Tmobile 3G and are unbranded by Tmobile?
The branded Tmo android phones lock out my Tzones.

Here's a list of phones that will work with tmobile 3G. Take your pick. You may have to source it from somewhere else if you wish to buy it unlocked and unbranded.
The Nexus S is unlocked and unbranded even if you get it from tmobile. But since you are coming from the Nexus One, it is up to you if its worth the upgrade. Other than the Nexus S, have a look at dual core phones.

Atrix on t-mobile
i am currently running atrix 4g on system version 4.5.141 and android version 2.3.6.. I am rooted and have and unlocked boot loader. I also got the unlock code for my phone and it was successful and i am now running T-mobile sim chip i am only getting the Edge .. I have a thought as if you could change the phone frequency settings with sqlite editor i mean if you can disable the entitlement_check to enable theathering with AT&T's 2gb plan then we should be able to figure out how to change the frequency ratings of the phone to be able to run on t-mobiles 4g ... I wish that someone with a little more Knowledge could help out with this..

Samsung Galaxy S II "confirmed" for Verizon in July

According to PhoneArea a Verizon spokeswomen has confirmed that they will be launching the Samsung Galaxy S II sometime next month.
http://www.phonearena.com/news/Samsung-Galaxy-S-II-confirmed-for-July-touch-down-at-Verizon_id19421
I'm sure AT&T will probably release it around the same time (if not sooner).

This is shocking...
"Although the phone will not be enabled for the LTE 4G network, it probably won't matter to potential buyers as the device has already proven itself to be speedy over 3G pipelines."
What's the purpose of launching a state-of-the-art phone that doesn't run on your state-of-the-art network? Hell, with EVDO, it'll be the slowest of the three U.S. SGS2 variants assuming it's Wi-Max on Sprint and 4G and/or LTE on AT&T. Why carry the phone at all?

Oh well, I don't even have 4G coverage here. By the time I do, I'll probably already be getting a new phone.
Also while I don't put much stock what an email from a Verizon spokesperson says, at least Verizon acknowledges the phone and it will at least come out eventually. I hope it really does come out in July though.

At least it will work on ATT's fake 4G HSPA+.
To work on Verizon's LTE would require a big redesign.

I thought it was supposed to be AT&T's first LTE phone? I read that online somewhere but can't find it now. AT&T was also supposed to be the first to launch so maybe the hold up is getting the LTE radio working. AT&T's LTE network is supposed to light up in a couple of weeks and they still have nothing that can run on it. Yet they're introducing a slew of high-end devices that work on a network that's outdated. Strange.
P.S. - Now that I think about it, it may be the combination of CDMA and LTE that prompted VZW and Samsung to skip LTE. That will still be strange though if Sprint's variant ends up being CDMA/Wi-Max.

Adding the LTE radio and chipset would probably require redesigning the phone. The current LTE phones are really big and thick.

Bad for AT&T but good for all of us who imported a non-branded SGS2. I assumed that AT&T's LTE version was going to make our phones (at least in the U.S.) outdated. If it ends of being the same phone with AT&T "enhancements" it makes our decision (and the price) worthwhile.

Excuse my ignorance, but what are the chances of the carriers making the phone better? I don't know how, just asking.
I don't know if i should just wait to see the differences with the ATT version or just buy the unlocked one now

You guys need to realize JUST how hard it is to design and properly tune for LTE bands. I work in antenna design, and I can tell you it takes quite a bit to tune the noise down on the LTE frequencies. Add that to the fact that antenna real estate is already extremely tight in an ultra thin device like the SGSII (especially when taking GSM, WIFI, bluetooth, and GPS into account), the only way to get LTE in would be to have one/several of the other bands to suffer AND/OR make the device much, much thicker.
Until active antenna solutions are more readily available, this will continue to be a problem with passive antenna design, especially with small form factor devices like mobile phones.

Another bad news for Sprint users and ...

another reason to believe that Sprint GN2 may not have SIM slot.
We already know that previously Sprint Photon Q (made by Motorola) have SIM internally and unremovable. Now we know that there is another Sprint device Optimus G (made by LG) that will have the exactly similar design as far as SIM slot goes. (source here)
With the previous picture purposely a leak of Sprint GN2 device showing no SIM slot, this is likely to be a Sprint own evil doing.
And BTW I'm one very pissed about this. I 'll definitely sending a snail mail to Sprint Executive Office about how pissed I'm as a consumer regarding turning an international capable device into useless crap once the device come out. I go to Thailand every year or so to visit family member and when I am there I would definitely want to use SIM there because of the local number I can use. With unremovable SIM this is no longer possible. I'm very disappointed.

That's sucks, although I don't go over seas that much.. It would be nice to have. Tell them you Ben kohn bah and your red shirt friends don't approve of this.

Unfortunately most sprint users including myself really don't care that much although it would be great to have definitely not a deal breaker for most and most won't care.

It appears that this is the route they are going now. I wonder why that is? Does using the embedded SIM force you to use a Sprint International plan, for out of country use?

pardon my ignorance, but isn't the "international" version GSM...and sprint's, obviously gonna be CDMA? and as such, no SIM card?
---at least i've always assumed that SIM cards is something GSM phones use, while CDMA phones do not.

You're right, but some CDMA phones have radios that support at least EDGE on GSM so you can still text and make phone calls overseas (and if you unlock, you could run them on Tmo and AT&T).
However, the question is if the radios will even support the EDGE GSM bands... probably not though.

All of Verizon's LTE phones have a SIM card slot and all of their recent phones also have GSM/HSPA radios for global roaming. I believe some can even run on T-Mobile and ATT's frequencies if you are lucky. But LTE will be Verizon only.

would it be possible to flash a Verizon Note 2 to Sprint in order to have one with a SIM card?

There are so much of competition in market, they skipping features users can easily find alternative. Bad for users but too bad for manufactures. They should understand

Not sure if you saw, but someone has figured out how to remove the embedded SIM in the Photon Q and replace it.
http://forum.xda-developers.com/showthread.php?p=32593285#post32593285

Yea, but whose brave soul gonna do that on not even a month old GN2. And that's beside the point. Seriously, to me it seem like it would cost the manufacturor even more to make the SIM embeded than regular one.

I mean how many sprint phones even support GSM EDGE bands?
I don't use Sprint, so I don't know for a fact, but don't their phones usually only run on CDMA (I've only ever heard of Verizon CDMA "world-phones")

I know that the old Touch Pro 2(wm6) and Photon 4G both have dual GSM/CDMA chip in them and they both have SIM slot.

whats the significance in not having a sim card cause it seems like a good thing to me. unless its like tmobile and att network where you can get gsm phones

The significant isn't about whether it have SIM or not. I mean for most people in the US I think we can get by w/o it. I mean it's like once every year or two that people would go outside the country and can make use of it. So it wouldn't be like a final decision whether to get one w/ or w/o SIM. And you are right there are also AT&T and T-mobile. But I can say the for some people it's about the network in their local, while for other it may simply be about not going back to the service they have bad experience with. To me it's about cost, since I'm a Sprint SERO Premium account owner. But very, it's more about why walking the low path? The phone would have been technically capable of it, the chipset, modem, antana support it. This is more about why purposely redesign it to lock it down to a specific network, greed, basically.

Yes, the Sprint HTC Touch Pro 2 most certainly had a SIM card slot. I had a few of them before making the jump to android with my EVO 4G. It was a nice feature to have on a "Business" phone, which is what the TP2 was geared towards. The productivity of the Note 2 also can be geared for Business users, a SIM slot would be of great use.

Ohh okk that makes sense. Cause I never go out of the country so its not that big of a deal for me. But I guess I'd you travel a lot it would be better to have one

Apparently Verizon figured out how to do it properly as they previously have had CDMA, but now allow removable SIM cards for their LTE world-phones. Sprint is now the only provider that locks their phones down like this- it's very frustrating. I am paying for a brand new device that is inherently compatible as a world-phone, but I must buy a separate device to use over seas so that I don't get raped with Sprint's international calling/data plans. RIDICULOUS! These kind of tactics are out of the apple playbook- limit the options of your customers, so you can squeeze em.

[Q] Possible to Unlock?

Hi I wanted to buy this pone from amazon, but the thing is that I would buy the sprint versión with no contract and I don't live in the US, so my question is, can I unlock this pone to use it with any other company? like Movistar? I read that the pone was GSM so I thought it would be posible, however I won't take the risk of paying 590 dollars for a pone that I can't use, thanks

The ONLY part about sprint that is NOT CDMA is LTE which the sim card slot is LOCKED to sprint.
They MIGHT be a fix but right now there is NOT. Some of the older phones like the Moto Photon its not LTE but its a world phone and people could flash a few things and make it work, But only EDGE in the USA anyway.
But as of right now and problay for a while its NOT going to work.

I expect Sprint will provide a method soon to unlock the GSM and UMTS functions in the phone to be able to use it internationally. However, I don't expect the GSM and UMTS functions to operate inside the US. Sprint has always disabld them on GSM capable Android and iOS devices it sells.

I don't see why it wouldn't work for you as long as you can get it unlocked.
Sprint is not going to unlock it for you unless you are a long time customer or have the phone with them for 90 days.
hyelton is completely wrong though.. the sim does authenticate lte on sprint but also acts as a gsm sim internationally.
you can also remove the sim and insert any international sim once unlocked providing the carrier uses the correct bands.

You are all kinds of WRONG.
Sprint's GS4 is fully capable of voice and data on international GSM/HSPA+/UMTS 850/900/1900/2100MHz networks. You have to request Sprint to unlock your phone's sim (or find a work around if you're not a Sprint customer), but once unlocked you can pop in any international sim and it will WORK JUST FINE on international GSM networks, they don't have to support LTE. Heck the only thing preventing the SG4 from working on US GSM networks is Sprint locked the Sim from using USofA GSM carrier sim cards.
As long as the OP can get their Sprint SG4 sim unlocked, they can pop in their international sim and use the GSM in their country NO PROBLEM like any other GSM phone.
SO ONCE AGAIN, Sprint's SG4 has a fully functioning GSM modem that supports international carrier GSM/HSPA+/UMTS 850/900/1900/2100MHz bands!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
You would think someone with almost 2,000 posts and who made a statement like "I KNOW my Cellular Networks!" would know better. Do yourself a huge favor and actually know what you're talking about before you go spouting off again, because you really made yourself look like an ignorant fool.

Well YES you can easily use your phone overseas, But it was POSTED in the Sprint Forum which is ONLY in the USA and in which using it does NOT apply in the USA. And to get the phone unlocked I`m not sure if a regular unlocking company would be able to do it someone with a sprint account would and it would be MUCH more trouble than just to pick up a ACTUAL GSM carriers Version of the phone.( I should had just said that to begin with) Its VERY pointless to TRY and want to use the sprint Version when they are SEVERAL OTHER varrients that are GSM they could have got to use.

EXCEPT... the op specifically said they wanted to purchase it from Amazon America to use on their country's GSM network.
Why they want to do that? WHO KNOWS, maybe it might be cheaper doing it this way, but that is what they want to do and despite all your unnecessary wrongful information, the OP can do what they asked as long as they can get the sim unlocked.

I sell on Amazon and Most people wont ship out of the USA on Amazon. Mostly only Candia but Ive tried ordering a lot of things overseas and 90% I cant as they wont ship here

Amazon sells the Sprint for $599 this is probably why. I bought mine at Best Buy and had them price match Amazon for that price.

Looks like everyone here is an expert in this matter but so far haven't seen a single link to reputable sources... OP call sprint international department and get answer straight from the carrier (888) 226-7212
Even IF the phone is capable of being used in GSM bands internationally, you would have to get it unlocked by sprint and they change policies all the time so just call..

I got my phone unlocked for international use. I contacted sprint international services. I was initially told that you have to be activated for at least 90 days before they could unlock the phone but would forward my request to some department. After one day I got a email that my phone has been unlocked.

Yea.... but it ONLY works internationally AND you have to be a sprint customer.
The POINT I have been trying to get across is that people need to understand Sprint is a CDMA carrier and ONLY relies on GSM for LTE. I think what people think is that they are solely a gsm carrier like most of the world is but its NOT

Question about bands

Just a little curious, since I've never done much carrier hopping.
Say I buy this phone from T-mobile, would it work on Verizon? My vz phone uses a micro sim as well, but I know there are different bands the carriers run off, and gsm vs cdma and such. But some phones work on both types, correct? Is this one of them? I really don't like the look of the verizon version...

No but if you buy it from verizon it will work on T-Mobile.
