AT&T version on T-Mobile - Samsung Galaxy Mega

So what could the AT&T version (i527) get on T-Mobile? Here is the listed specs;
GSM850, GSM900, GSM1800, GSM1900,
UMTS850 (B5), UMTS900 (B8), UMTS1900 (B2), UMTS2100 (B1)
LTE700 (B17), LTE850 (B5), LTE1700/2100 (B4), LTE1900 (B2)
If I live in a refarmed area with LTE would I get both LTE and hspa+?

Yes you would get both T-Mobile's LTE snd HSPA+.

So does that mean that the AT&T version will work perfect with TMobile?

In theory, yes. You certainly should get LTE and HSPA+ data connectivity since AT&T and T-Mobile both use the exact same frequency bands for those services. However, you won't know how fast or how slow your data speed will be until you are actually using the AT&T Mega on T-Mobile's network. The modem plays a big part here.
For example, I had an unlocked AT&T Galaxy Note LTE that I used on T-Mobile. I flashed various modems that were ported from different devices. A modem ported from a T-Mobile (non-LTE) device gave me HSPA+ speeds around 15mbps but no LTE at all. Since the T-Mobile phone from which the modem was taken did not support LTE, the extracted modem did not support LTE. Meanwhile, a modem ported from an AT&T (LTE) device produced LTE speeds around 22mbps but HSPA+ speeds of only around 8mbps. The point? Your mileage may vary.

Yeah I had an unlocked Galaxy Note 1 from At&t and I was using it with Tmobile which worked pretty good a while back. Hopefully I can pick one up. Thank you. ..

thanks for the replies. Anyone want to take the plunge? I am stuck til Thanksgiving on Verizon and am looking to go to T-Mobile. Hopefully someone will play with it to see how reliable it is out of the box.

If I can get my mega unlocked then ill let you know how tmobile performs, thats all i need

seems weird. were you going to pay full price? shouldn't matter if you are a customer or not. have you tried online?

Yeah I was going to pay full price it was stupid I couldn't buy it. I think maybe cause I told them that I wanted to buy it but for them to unlock it for me. I think I'll just go to another store and get it unlocked somewhere else. ..

that's exactly what I was going to do. I wonder if you told them it was a gift? I don't know, but it seems like there has to be a way to get it through AT&T.
I tried on their website and it said the same thing about signing up for an account. I guess I will get it when it pops up on Amazon. I wonder if AT&T will unlock it even if we aren't customers.

So am I correct in my understanding that the only version that has Tmo bands (4g and lte) is the AT&T version?
All the ones on amazon are a great price 450$ but are international versions.

That's correct. The international versions will get you HSPA+ but not LTE on T-Mobile. The AT&T version is the only one that has the compatible T-Mobile LTE frequency bands.

Is the phone unlocked? If not, you will not be able to use it on T-Mobile's network. If it is unlocked, try "fast.t-mobile.com" for the APN (leave out the quotation marks).
If it is unlocked how did you get it unlocked?

Yes, I am unlocked. I used an internet unlocking service. The phone automatically sets itself up with the epc APN. I looked up the "fast" APN and it didn't connect. I hard reset the phone and it reset to epc.

What unlocked company did you go through cause I had no luck finding one for the AT&T model...

Since T-Mobile actually encourages people to bring their unlocked phones onto their network, they should gladly help you with setting up the APN for your LTE device.

galaxy s II works on tmobile 4g network usa??

I am really itching to get this phone, as my contract is going to be done within weeks. I know that the EU version wont support tmobile 4g. How about the Canadian version??? the bell/ virgin galaxy s II 4g. Would this version work tmo usa??
Check the bands. Google it. If they're the same then it will work. AT&T's 4G network will work with European and Canada's will also I believe.

that's the problem, I am new to this stuff and willing to learn. Let's start with what BAND is, and how do I check that BAND.
I am not 100% sure. But I believe that it well not work on T-Mobile USA 4G network. It uses different frequencies. If the SGS II ever comes out on Rogers then it will work on T-Mobile USA.

You are right. And once the merger goes through the T-Mobile 3 and 4g phones wont work on 3 or 4g. This was already stated by att and tmobile

By that time the Galaxy S III will come out lol. But I will definitely love the HSPA+ speeds on my SGS II.
If you really want it either:
1) Switch to AT&T, you will get 4G speeds
2) Wait for the Samsung Hercules to come out on T-Mobile (Should be this or next month)
In the end, all people who buy T-Mobile phones now will eventually suffer later on. ;D

Dude,
It works very well! I have the AT&T Note... I unlocked it ($25 on ebay, I prefer this method as the seller has a reputation to protect). I then had it rooted, then flashed over to T-Mobile (http://rootgalaxynote.com/).
I did a test on the $30 - 1,500 minute plan (only 30 megs of data) to see how it works. I did this before flashing the modem and the 2G/Edge doesn't work well at all for the Note. However, after flashing the modem, it screams on TMO's 4G.
Good luck to you, but flash it and don't look back!

But just as a heads up, the exynos chip in the international version is not LTE equipped. So, if you get the international model it won't work on Tmobile's 4g bands even if you flash/hack/pray to the cell gods or anything else to your phone.

I'm not totally sure but, I believe if you get the international it will work on tmobile's hspa+. You shouldn't have to get the AT&T version if you just want to use the phone on tmobile and, are ok without LTE. Hspa+ is still very fast.

T-Mobile doesn't even have LTE so it doesn't make a difference.
The AT&T Note is the only one that works with T-Mobile 4G which again, is not LTE.
Also, no the international version does NOT get T-Mobile hspa +.
The international version ONLY gets EDGE on T-Mobile.

Sprint Galaxy S 3 (USA) vs international galaxy s 3 question

Here is my issue. I am currently in the US. I might teach ESL overseas in Korea in January. I am not sure which phone to get. Will the USA one work over in Korea? Will thew international one work in the US?
It could work but Sprint has the radios locked.
Would developers be able to get them unlocked?

The international one works in the US flawless... just not on all carriers... it works the best on AT&T if you want to use it in the US and get 4G(HSPA+)
You can use it on T-Mobile but you will have to settle for EDGE(2G)

It would work on most carriers which uses the international frequencies.
Not just AT&T for US. Works with Rogers, Fido, Telus, and Bell Mobility in Canada for instance.

Just a side note, HSPA+ is not 4G. It's still 3G. LTE/WiMax is 4G.
so which companies will it work with 4g/lte? Will it not work with Sprint? Anyone know any deals for the international version?
Sprint (and Verizon) is on an old CDMA network while the majority of the world is on GSM, you know, operating with a SIM card. If you're set on travelling, it's better to get any of the GSM-variant, that way, you can just pop in any sim card from any major carriers all over the world.
I currently have a photon which has a sim card slot in it. So the Galaxy s international wont work on Sprint? Damn I want to keep my SERO plan lol. So where can I get an international verison from? Also would I have to pay full price for it?
Does the photon has an active sim card in it? I'm assuming no. I've never used a dual-mode phone before (nor am I familiar with how they operate on different networks), so I dont know the ins-and-outs on how to get it activate for a GSM carrier.
Damn, now i have a headache just trying to figure out how it works to have an intl GSM phone on a network that is predominantly CDMA whom happens to offer a dual-mode phone on their network

The SIM in the Photon is just for roaming. Sprint does not use SIM cards - even their LTE phones have them embedded rather than user-accessible.
As the Sprint Galaxy S III is not a 'global' phone - i.e. does not have both GSM/UMTS and CDMA radios - do not purchase it if you have any intention of using it outside the US. CDMA is no longer a global technology.
Confuses me a little that people spend so much on devices without checking what networks they support. Ho-hum.

Works exactly the same for me using an AT&T SIM in the T-Mobile HTC one. The other way around, I get less HSPA+ service using an AT&T SIM in a T-Mobile HTC One.

No. The AT&T one doesn't fully support T-Mobile while the T-Mobile one fully supports BOTH T-Mobile and AT&T.
For people who don't want CDMA-based service, the T-Mobile version is the best one to buy for compatibility.

Are you sure about that, Maybe the AT&T version needs to be unlocked for it to work on T-Mobile's HSPA+ Network. I hope like hell it does because I would like to have the 64gb version working on my Network of choice, T-Mobile of course.

This has been discussed to death on the boards.
All the phones have the same internal radio hardware but what's been flashed to each device is different.
i got a att version unlock, big mistake for tmobile. i flashed tmobile rom and radio. alot of places in new york i get 2G which it was constant 4G with my note 2. Place where i get 4G i only get 7mbps. while with my note 2 i was able to get up to 18mbps. Order the tmobile version will return this one. The only reason i bought this is because they had it locally in ATT store while tmobile htc one is on backorder and not avail in any store.
Unfortunately Samsung doesn't just make the same model for both I would imagine it would save them money also but att phones work slow on T-Mobile but other way around your golden

I don't think the radio from the ATT LGOG works with TMO LTE.
Is there anyway to flash another radio that would let u get 3g or 4g something other than Edge.
Sent from my LG-E970 using xda app-developers app
I just ordered this phone today so I can't speak from experience, but T-mobile LTE should work with the right settings. From what I've read the AT&T Optimus G (E970) has support for LTE on frequencies 700mhz and 1700mhz, T-mobile also uses 1700mhz for their LTE. Some areas in the US might let it get HSPA as well. If everything is unlocked and you're using a T-mobile SIM card then you should just need the correct APN settings. This link should help:

Hey - just went through this for an ATT i747 (Samsung Galaxy S3). Someone in the forum provided the Tmobile bootloader, modem and platform and att CSC. It ended up being what T-mobile used to tested their LTE network using ATT i747. Works great get 4G LTE. Figure will need the same type of code for the LG-E970 bootloader, modem, and platform. Still having to use ATT CSC.
On the other forum they offered up a bounty to get it done.
Could do the same thing.
You're the millionth person to ask. No, it won't work. Not going to bother pointing out why anymore. No tmo version of the lgog exists.
