Galaxy S II 4G? - Galaxy S II Q&A, Help & Troubleshooting

Just seen an ad on TV for Galaxy S II 4G? (In Australia)
sent from my Motorola XOOM using XDA Premium HD

it depends which version of SGS2? so far that i know the international i9100 isnt capable of receiving 4G... and so far that i know (might be wrong) the only SGS2 version that is capable of it is: Galaxy S II Epic 4G Touch... which is SPH-D710

I think the 4G is only compatible with the Telstra network.

What you mean?
4g=HSPA+
LTE is different....

Telstra are in the process of rolling out an LTE network.
Edit to add - As Victor said, only really useful on their network ATM. Voda/Optus to begin LTE rollout 'later this year' (apparently).
Further edit to add - Plus there will probably be about as much custom firmware for it as the I9100G (at best).

HSPA+ is evolved HSPA which isnt TRUE 4G... its more like 3.5G
LTE is true 4G..

Wrong 4G and LTE are totally different. New iPad only works with LTE variant of 4G which we don't have in OZ. We already have 3.5g and that is HSPA+.

[Q] Does the SGS2 have 4g?

Does the SGS2 have 4g support like the Atrix? Hard to imagine a phone with these goodies doesn't have 4g.
No it doesn't.

No but does have 3.5G (H)

Yes it does, it has 21 Mbps HSPA. Call that 4g if you want, that's the fake 4g att is claiming.

One Good thing i have noticed : it shows G when idle and H+ signal when ever I am using data.
Atrix is only 14mb/s where as this is 21mb/s so its theoreticaly faster

4G right now is nothing but a carrier marketing gimmick, but yes our SGS II's have support for AT&T's (formerly known as 3G until T-Mobile made it cool to call it) 4G network. I wish it was LTE capable, but I suppose that's what the SGS III will be for eh?

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

can i use rezound is gsm band?

i'm in thailand and my cousin will buy me this phone if it can be unlocked to use with gsm but i dunno it can use it or not
thanks and sorry for my bad english
Unfortunately the Rezound is not GSM compatible. I would suggest the Sensation XE as the closest alternative that is GSM capable.
This phone will work on a compatable cdma network but not on gsm network. Not a world phone.

Gt-I9300 international on U.S. T-mobile

Just curious, I have the international and I am on T-mobile in the U.S.
Will the I international ever be able to attain 4G Speeds on T-mobiles network? For instance once quad cores become the norm in phones (like they are on the verge of doing).
Or would I be better off selling and getting a T-mobile g3?
Thanks in advance.
Sent from my GT-I9300 using xda app-developers app
well, as far as i know by end of this year we will be able to use 3g or hspa+ but for now i am sticking with 2g
or just change your mobile network, get straighttalk or att

Ok. 3g would be great. For the most part that is what is in most areas anyway. I just wasn't sure if it was our phone that didn't have the right radios or if it was T-mobile/other carriers that didn't have the right modems for our exynos.

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.
Thank you very much for the update guys... I'll see what I can do...

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

I have i777 working on tmobile with 4g. My wife has tmobile so when I upgraded to the GS3, I unlocked the phone using the code from AT&T and I get "4g" on T-Mobile. I did a speed test and was able to get good speeds.

Sorry for the late response, I haven't been on here much lately.I live out in Little Elm, slightly past Frisco close to Lewisville Lake and 380/University. I am about to upgrade my phone again and give my wife the GS3. haven't decided between the GS4 and Note 2 yet.
I am in So.Cal and got 4G out of Edge half of the time from Tmobile ofcourse. The speed is around 7-10Mb/s or so
is there a rom ported from att to T-mobile
