Galaxy s 2 will work on which carrier? - Galaxy S II Q&A, Help & Troubleshooting

If I purchase the sgs2 from Europe I know it should work with at&t and T-Mobile here in the USA. My question is will 3g or hspa + work or just 2g
The Herb Frees Your Mind

It's said to have AT&T's 3G, but that it should work with any other carrier, which pretty much means AT&T 3G(and HSPA+), T-Mobile 2G.

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

Anyone using Atrix 4G unlocked on T-Mobile?

It will always be slow since its on 2g, nothing you can do.
Why aren't there laws that make it so cell phones are all interchangeable? Something like consumer freedom so you can buy any phone you want and use it on the carrier of your choice.
Use straight talk. Hspa compatible.

Actually, T-Mobile has said they're going to start adopting AT&T's 3G bands with the hope that Apple will let them sell subsidized iPhones. So depending on where you live, you may get 3G on the Atrix. I agree though, more interoperability is needed. This GSM/CDMA split we have is ridiculous.
I'm not using T-Mobile right now, but in a year (when my contract expires) I'm switching to one of their value plans and will unlocking my Atrix to use with them if I'm still happy with it. Given that so far the only spec I see improving on newer phones is the screen resolution, I think it'll still be plenty usable when that happens.

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.

Both white and black are the same, yes you will get 3G and 4G coverage on at&t since 4G is hspa and at&t supports hspa.
No this phone doesn't have lte and just a heads up, though you will get 4G, it might not be as fast t-mobile from what I've heard, their HSPA isn't that fast but still pretty decent.
I appreciate that.

ST does support 4G but right now my tower is under a full noon load.
12 noon speed is awful but 12 midnight speed is great.
At&t doesn't keep up on maintenance with these towers.

I used to work for Business End User Care for AT&T. As of the time I left (november), if you placed your sim in a smartphone and used it for about a day the system would add the lowest data plan and send you a text message indicating it had been added to your account. Even if you were using someone's phone while your "feature phone" wad being replaced, it was required. I've had to read that section of the TOS to many, many angry people. I would call and confirm just to be safe.

DO NOT CALL to ask..... as they won't know the answer, and might put a note on your account to force a data plan(well, you could call and ask on someone else's phone without giving your account number)
the primary way (so far that I've seen) that AT&T detects your smartphone is via IMEI. Secondary might be you using >100GB/month, connecting to their 4G APN settings, going to a store for help and letting the customer rep see that you have a smartphone
does AT&T have your IMEI? probably not.... AT&T has IMEI of all of their smartphones, so you can't use an AT&T smartphone. You can try using an (unlocked) t-mobile phone, but might not support the right 3G/4G bands that AT&T use. You can try international phones, canda phones(from Bell, Telus...). WARNING>>>. AT&T might have your IMEI because the manufacture gave them the IMEI(See Google Nexus phones), inference from branded phones that they carry(eg Phone is sold/branded by AT&T and t-mobile... AT&T gets a list of their phone IMEIs that might include t-mobile's IMEIs), screwups(Samsung Note overseas was misentered as a tablet on AT&T's network, white i9100 Galaxy SII is misentered as a Blackberry on AT&T's network)
The link at the end of this post gives a guide to what phones are 100% compatible(3G/4G on 850/1900) on AT&T's network.
According to this, the T-Mobile Amaze 4G is compatible with AT&T 3G/4G, but I have some confusion on the 850/1900 mhz band for the 3G/4G data, trying to sort it out(last few posts on that thread)
Guide to what phones are 100% compatible with AT&T's network
anyways, quick update
got a T-mobile Amaze 4G to play with
(with unlocked bootloader, S-Off, Super CID and SIM unlock, all available on this forum), works on AT&T 4G (HSDPA)
speeds right now ~ 1000 kbits/s up/down, hard to test because my location is spotty

I777 working on tmobile?

Hey guys...Im doing a favor for a friend...he just got the I777 rooted ...but he wants to use it for Tmobile...what do i need to change for it to work with a custom rom...and then again can i port a rom from the tmobile S2 ...just modem?any input would be appreciated..
Edit:i have the E4GT on sprint...so i'm not really familiar with the gsm models...
While I should say use the search bar, all the information I've found is pretty outdated regarding this.
The simple answer is that you probably can't get it to work, at least not 3G/4G, if Edge is fine then you can unlock the phone with "Galaxy S Unlock" in the play store, just follow the directions listed, it's pretty simple.
The extended answer:
You might be able to depending on where you are. T-Mobile generally uses the 1700 MHz and 2100 MHz bands for 3G/4G, but the i777 doesn't use the 1700 MHz bands, instead it can use either 850, 1900, 2100 MHz bands for 3G/4G. However in preparation for LTE and just to increase bandwidth across 3G/4G they are starting to take some of their 1900 MHz spectrum from their edge networks and move it to 3G/4G/LTE. This has just started happening very recently and is currently in very few markets, however you may be in one of those, it is still expanding if you aren't but it may take a while. The only way you could know is if you took a T-Mobile sim card and put it in an unlocked i777 and if you get 3G/4G then you are good, otherwise you are stuck with Edge.

The S2 for ATT doesn't support 3g for T mobile and vice versa. There could be some weird instance as mentioned above where it could work but in most cases it won't.

Mostly true, T-Mobile's S2 should work with AT&T's network, you may have to flash a new radio but theoretically it should work.
You cannot port a T-Mobile ROM because T-Mobile does not have a similar gs2. The T-Mobile gs2 is the twin brother to the skyrocket
