I have an atrix that is unlocked and has a T-mobile sim card. But its stuck on Edge and never been on 4g let alone even 3g. Is there a custom rom and/or kernel that can fix this issue?
The atrix isn't 4G capable (lacks the hardware) and T-mobile uses a different frequency for their 3G networks that the Atrix doesn't support.
So yeah you're stuck on edge as long as you're using T-mobile on the atrix
Seriously?

I have been considering the Atrix 4G from AT&T. it is advertised as 4G by ATT. I ready a couple reviews that said it was slow, but I assumed that might be from all the bloatware. I guess I should be looking at a different phone, if the Atrix 4G is really not 4G.
First find the specs of the device. Only devices listed as LTE are real 4G. You can find it in radio frequencies. At&t only has a few but verizon has a plenty to choose, although according to user feedback 4g devices are battery hogs, while on 4g of course.

If you want fast / reliable data speeds you best be looking at a different carrier than AT&T.

Well that sucks... I guess I'll be continuing my search. I'm new here but am loving the available information and the responsiveness of the members. Thanks again.

After CES, I'm beginning to put some serious thought into LTE and this phone. Dumping AT&T at this point is looking fairly good, as I've loathed their customer service for consistently soft-bricking my older phones due to their inability to properly unlock a phone.
How well does this phone handle roaming, especially in Japan, the UK and Australia? How compatible is the CDMA2000 EV-DO Rev. A. standard? I need to do a lot of travelling to these places and don't want to be short-changed. Does this support UMTS 2100 or international 4G? I plan to use the "buy a prepaid SIM" method.
Or should I be carrying around my unlocked Captivate for roaming?
If you want traveling to Western Europe (like in UK), forget it because GSM rules there. Just notice that the GSM represent 80% of mobile phone market but there is a website you can find the CDMA coverage in the world:
http://www.cdg.org/worldwide/
EDIT: About the 4G, a very very very few countries have it but it can be HSPA+ or WIMAX instead of LTE.
Another website for GSM coverage: http://www.worldtimezone.com/gsm.html
So, what you're saying is basically: Tote around the Captivate if I'm going to Europe, use the Thunderbolt for Japan?
In short answer, Yes
But you can't use the 4G Lte in Japon because it doesn't exist (yet).
Anyway, there is one carrier available which support the CDMA in Japan according to the website.

I do know that KDDI supports CDMA2000 and 1xEV-DO Rev. A on the right bands in Japan, so I'm hoping that it's enough. I don't need data roaming that badly, and if its service is comparable to Verizon's EV-DO service, it's good enough.
If youre gonna roam, bring along the captivate.
Or, you can get the droid 2 global, but there's no lte in there lol

Sir,
I want to buy Galaxy SII duos. It works with CDMA2000. However, I used to go to Hong Kong. I want to use 3G (i.e. WCDMA). Can I root the ROM so that it can works with WCDMA?
OK I have searched and can't find an answer to a couple of questions.
I am coming from a rooted Epic 4G on Sprint. I am not familiar with unlocked gsm phones. I am switching to att because i am moving to an area with bad sprint coverage.
I was going to buy an Infuse, but it seems the Galaxy S II is better. I understand i can use the SII on att's network but i am unsure about a couple things.
1) will i be able to utilize their semi 4G data network? When they get 4G LTE, will i be able to use that?
2) what downside is there to going the S II route vs an Infuse other than $$? Looks to me like the SII is way better.
Anything else I need to consider?

The international SGS2 phones you can buy today don't have LTE, so they won't work on the AT&T LTE network. They will, however, work on AT&T's HSPA+ network -- I regularly get about 4 Mbps, and have gotten as high as 7. You can use a regular 3G plan on the HSPA+ network; I have the old $30/month 3G smartphone unlimited data plan, and I haven't had any problems connecting to HSPA+ in places where it's available.
There is some speculation that the AT&T version of the SGS2 (called Attain) may have LTE support. Unfortunately, this phone isn't available yet, and as far as I know, no release date has been announced.
Thanks for the info. As a practical matter i shouldnt worry too much about LTE. I live in a rural area which just got 4G, but is very ulikely to upgrade to LTE anytime soon. I will probably want another phone by the time we see LTE here. Now i have to decide if i want to spend $450 more to get the SII over the Infuse. The SII has more RAM, dual core processor and higher res second camera (bfd). Im not sure what other improvements.
Any other advice or insight would be appreciated. Im sure gonna mis the hardware keyboard on my epic!

hELLO,
sorry if I post here I don't know if its the right section. I'm looking for a phone for a friend that can be use either with t-mobile and att in 3g or 4g.
I know that they use different frequencies but I was wondering if there is a phone that supports both frequencies for 3g and 4g speeds, or if there is a way to change the radio and make it work. Thank you so much..
To find a 4g phone is not that simple as I thought.

Well at&t nor Tmobile has a true 4g network at this time. They both use a 3.5g network that they advertise as 4g.

Can someone shine some light onto this situation for me. I have a bell Gs2 and i heard they are releasing a lte (4g) network in toronto and that they are rereleasing the gs2. Does that mean i bought my gs2 and wont be able to take advantage of the lte capabilities?

Yep, our phone has HSPA+ which Bell considers 4G along with their LTE network. Your phone doesn't have the LTE hardware, so yes, you are right. You will not be able to utilize LTE on your new phone....
Poor show by Bell there TBH man. At least here in the UK we know we are all being soiled on by the complete lack of 4G at the moment, over in Canada it must just be confusing as to which 4G platform your phone can...and can't, accept.
Thanks for your insight on this situation guys

I don't think it matters TBH, Bell is charging a whole lot more for the LTE network so unless you are willing to pay you are not getting on it. Besides do you really need that fast of a connection (in a very limited geographical area) other than bragging rights?
The Galaxy S II is still a great phone. The LTE network will have only a small coverage area and a small number of devices supported at first. In 2 to 3 years LTE phones will be widely available and coverage will be up, that's when I'll jump on the LTE bandwagon.
Until then, HSPA+ @ up to 21Mbps is fine by me.
LTE at the moment is a huge battery drain, and real world speeds are not much better than hsdpa with enhanced backhall aka h+
It's a shame they are using 4G to describe h+, it's a huge marketing mess.

I was thinking about buying the International unlocked Galaxy SIII GT I9300 and saw how it would be cheaper in the long run, but my main motivation was being able to move from carrier to carrier if I wanted to and not having a contract. I seem to be reading though that the international version is only compatible with AT&T and T-mobile at 3G and is not capable of 4G speeds at all. Also, that even American versions are not always compatible with eachother. So am I correct in thinking that if I get an international version I'll be stuck between T-Mobile and Sprint at 3Gs. And that nothing can be done to the phone to allow an International phone to work with Sprint or even an American Sprint to work on a T-Mobile network? I'm starting to think it might be easier to just get an American phone and jailbreak it.
The international one will never work with sprint or Verizon, the AT&T and t-mobile versions will never work with sprint or Verizon.
The difference is hardware, Verizon and sprint are cdma, the rest are gsm.
The international one will work with AT&T with 3g and 4g(actually its hspa+ which is technically 3.5g) and will work on T-Mobile only in 2g for now, in a few months it will work on 3g and 4g when they refarm their 1900 or 1700mhz (can't remember which) band to 3g.
No matter what you do to either the international or US gsm versions they will NEVER EVER WORK ON SPRINT OR VERIZON.

I see, that's what I was afraid of. The AT&T and T-Mobile option still seem attractive, but in your opinion will the Verizon/Sprint with a jailbreak route be better in the long term since the LTE is by far the superior option(from what I've read)? I've seen AT&T has LTE but the International version wouldn't be able to work on a LTE network anyway, would it??? I plan to download most things on my laptop and move them to the phone anyway, the only important thing to me internet speed would affect and my main concern would be live video chat, would the 3G or HSPA+ be sufficient for that? Other than talk and text the phone will be mainly used for games, movies, music and the superior GPU in the International version I think would be better for that? Are there any other phones comparative to the Galaxy III you know of that might have both the CDMA and the GSM, the "world phones" as I've seen them called?

You can't/don't jailbreak Android phones. Hard to even know what you are talking bout trying to accomplish? It's very simple.
1. Buy a phone from a carrier and use it on that carrier. That's the easiest option.
2. Buy an International GS3 and use it on AT&T 3G or 2G.
3. Buy an International GS3 and use it on T-Mobile 2G.
If you try any other options you are just going to confuse yourself.
Definitely don't get the sprint or Verizon ones, you are stuck on cdma then. The at&t one has LTE and the T-Mobile one has dc hspa+ (theoretically up to 42mbps) the international one has standard hspa+ (up to 21mbps) and I regularly get between 5-8mbps down and 2-3mbps up and I live in the country.
The gpu and cpu on the international one are better too.

I have a bad habit of using the words root and jailbreak interchangeably, I meant root the phone. I guess I have to decide how important LTE is to me. It'll either be AT&T or the International version. The superior GPU and CPU are attractive, but so are the LTE speeds. But I guess with the limited data maybe not. But thanks for your help, this clarified a lot for me.
Frequency Concern
I have the exact same problem!
I am planning to buy a Galaxy Nexus, which works for UMTS (850/900/1700/1900/2100MHz) and GSM (850/900/1800/1900MHz). I read from wikipedia that the 3G and 4G networks from Tmobile are carried on the frequency of both 1700MHz and 2100 MHz. Does that mean Galaxy Nexus can use 3G and 4G on Tmobile network?

Oh really?! Then I should sell my international version of Galaxy S II for a Galaxy Nexus. S II doesnt receive 1700MHz. I read from Wikipeida: This band (Tmobile 3G and 4G) was an area of wireless spectrum, half in the 1700 MHz (1.7 GHz) and half in the 2100 MHz (2.1 GHz) frequencies. SO I was thinking: Hey, how about getting a phone with both 1700 and 2100MHz to work on Tmobile 3G and 4G.
So you can actually use 3G? or even 4G on Tmobile? Is it so slow or weak that makes you want to change carrier?

Help, I have an I9300 and I have tried for a week to get AT&T GO set up for data. I can talk and text fine, but no luck with data AT&T says it is my phone. Under mobile network state it says disconnected. any help would be greatly appreciated. It is an unlocked international GSM phone.
I have a Samsung GT-I9300 unlocked Gsm phone. I have started AT&T GO $60 data plan. I have tried for a week now to get data with no luck. I can talk & text fine, and it works great off of WI-FI. AT&T has tried everything they can do and says it is a problem with my phone. I was previously on Straight Talk but was stuck with EDGE speeds and not good coverage. Any help would be greatly appreciated.
