Hey whats up erybody?
Im new to the forum as well as the android flashing/modding scene as i've always had an iPhone but recently gave in to this Galaxy sII as it looks and performs amazing. The only issue I have currently is I own an ATT Galaxy sII that is unlocked and I am using for T-Mobile but cannot get any 3G/4G network at all.
This phone is rooted and running cyanogen mod on ICS 4.0.4. I have read online about people flashing there ATT Note's radio to force your phone to accept 3G/4G for T-Mobile and I was just wondering if this is possible for the Galaxy SII? I tried using the same method but no luck, can anyone possibly point me to the right modem to install if one is available? This phone is great but I cant stand this slow ass EDGE signal.
Thanks :cyclops:

First off, you're in the wrong forum for your device.
This is the forum for the i9100, the international Galaxy S2.
You say you have the AT&T Galaxy S2... Which is the SGH-I777.
Second, since ATT and T-mobile use different frequencies for high speed mobile data, most devices for ATT will only get Edge on T-mobile. Vice versa, most devices for T-mobile, if unlocked for ATT, will only get Edge on ATT's network. SOME devices you can flash a different modem, because they have the requisite antenna hardware to get the necessary frequencies.
Unfortunately for you, the SGH-I777 isn't one of them.
Unless, you actually have the Skyrocket, which is the SGH-I727. (check the label under the battery to get the exact model number) That phone, you CAN flash a T-mobile modem to it and get high speed on T-mobile's network.
Ahhh I see. When I power on the phone it displays the international model however in the menu settings it does say SGH-I777 which is why I was a little confused since there are so many differen't models aparently.
Looks like im screwd until later this year when/if T-Mobile does go good on there word that they will be acquiring new towers to promote the other frequencies for ATT devices. Thanks for the reply.

The boot screen and indeed, the about phone screen can change depending on what is flashed to the phone. So if you flash an i9100 firmware to an i777, it will then display the wrong model when booting. Which is why I said to check the label under the battery to be sure.

CTOMGEE,
I have the i9100 International Galaxy S2 and am wondering if I can access 3G speeds on T-Mobile? I know the phone is not 4G compatible, so unfortunately I won't be able to access those speeds, but I am wondering if I will be forced to use the EDGE network.

Not as of now. T-Mobile in the US uses AWS currently for 3g and "4g". This band requires both 1700 & 2100 mhz for data to get these speeds. The phone doesn't get 1700, do it won't get higher than Edge.
There are rumors T-Mobile will be re-purposing 1900 mhz (which the phone DOES get) for data, so if and when that happens, the phone will probably get high speed mobile data. But until then, you're out of luck for T-Mobile with this phone, and will have to use ATT to get high speed data.

Hi ctomgee and others, I'm using a Galaxy S2 GT-I9100 that was bought unlocked. I'm also getting only 2G speeds on T-mobile. Could you tell me what is flashing the T-mobile modem and how it is done? Can I try to do this so that I can get 3G speeds? If this is not possible, would I get 3G speeds if I buy a S2 from T-mobile?
On the sidelines: What do they do to the phone that the phones bought from T-mobile would work but the others won't? Is it something done to the hardware or the software? If the change is in the software, can't we try to do it ourselves - are there any online tutorials on this?

Flashing a modem is essentially changing the software drivers for your antenna. This does not, however, change what frequencies your phone is capable of receiving. This is a hardware limitation.
The T-mobile USA Galaxy S2 is model number SGH-T989 - a totally different model than the GT-I9100. The hardware is completely different. The size itself, the CPU/GPU/SoC, the antenna hardware - all different. This isn't something you can fix with flashing a modem.
If you are patient, as I stated above, T-mobile USA is in the process of re-purposing a frequency the I9100 DOES get so it will get 3/4g on T-mobile. When that happens in the market you are in is up to T-mobile.

I spent hours online chatting with support trying to get this information and they couldn't provide it. 10 minutes of internet searching and you said EXACTLY what I needed to know. Thank you sir!! Helped me a ton.
Also, just a heads up. At the end of this year (2012) T-Mobile is going to launch their 1900 mhz band towers (see: newsroom.t-mobile(d0t)com/articles/4GNetworkEvolutionVendorsSelected) so AT&T phones that use that 4G band will work with T-Mobile once unlocked and moved over.
Thanks again!

Looks like i occasionally get the 4G speeds on tmobile on my i9100, but it switches between Edge and 4G quite frequently. Anyone know how to force a 4G?

You can set the network mode to WCDMA only... but I think there's a problem with that. If you wander into an area where T-mobile doesn't have "4G" coverage on 1900mhz, then I don't think you'll have any signal at all. When it is set to GSM/WCDMA (Auto mode), it switches automatically to Edge if you don't get the "4G" signal.
Wrong forum, this is for the international i9100 not Skyrocket.

The OP is from July. The guy above me today was asking a general question, and ATT sells TWO variants of the GS2 - the SGH-I777, which is their branded regular Galaxy SII, and the SGH-I727, which is the "Skyrocket" - which is the variant that has LTE.

Agreed since we are missing 1700mhz here but I was wondering whether its possible to capitalize on the 1900 mhz freq.

hello every one I was wondering I have the i9100 and I have metropcs on it and I also flashed omni rom on it but I was thinking that I need to flash the us radios on it because I got it from Japan and as I can make calles they drop alot and the network is so slow so is this something where I would need to flash that ? and if so can someone post a link for the file's?
Hi, everybody. Things happens so I left my US phone in Warsaw's taxi being there for Euro-2012 and bought Galaxy S2 I9100 from Orange. Came back to US and was trying to configure internet connection and had no luck getting 4G speeds. So far on the phone it just showing EDGE and low speeds. Is there any way to fix that issue? Was trying to search for this on the forums and Google, just found a couple of ideas that it doesn't work with 4G for some reason.
Any help would be appreciated!
Not sure if polish sgs2 have 4g (Lte) at all. If you want 3g you need to change APN settings for your providers default. You will find it in web.
Other possibility - you have no coverage of network .

If you're on T-mobile USA, you'll never get better than Edge speeds on their network with an i9100. The phone doesn't have the requisite antenna hardware to receive 1700 mhz for UMTS, which us one of the two required frequencies of the AWS band. (the other being 2100 mhz)

You're right, the i9100 does NOT have LTE. He's trying to get what passes for 4G (HSPA+) on one of our US carriers. I'm trying to determine if it's T-mobile USA or AT&T.
I totally missed the carrier name right in the thread title. Simple Mobile operates on the T-mobile USA network. So, I'm sorry to inform you, but you bought a phone that will never get 4G on your network. Sorry.
What about 3G? Or because of the antenna frequency difference not even that?

Same bands. So same problem.
Hi everyone! I been noticing that my i9100 is not running edge anymore but rather it has an H or H+ on the signal bat. Is this HSPA+ speed on the phone or am I just being too excited? I think this is because of T-Mobile running the new bands. If I can I will screenshot it when I see it again. So does anyone have the same thing as me? Thank you!

You should have posted a question in the q n a section. However for your information in the UK with t mobile I have had h+ speeds for roughly two years. It's got even faster on ee even though still h+ not 4g.. And 3 network gets even faster speeds on h+
Sent from my GT-I9100 using Tapatalk 2
Same here. I have had H+ for years. I only ever get edge when I'm in a very low signal area.
He's talking about T-Mobile in the US, which runs HSPA on different bands than in Europe.
Well, until recently, anyways. They have been in the process of re-farming the 1900mhz band for this use, so depending on the market you are in, you may have gotten it. So if that band is turned on to HSPA where you are, you'll get it on the i9100.
@mattisfaction well it did not seem like a question. I was trying to see if anyone had it like me.
@ctomgee he is right. I was talking about T-mobile USA. But thank you for answering my question. This is amazing! I love my i9100 even more now!
I have a I9100 that I usually use the XXLPS modem from Germany on. However, the strongest signal I am getting is edge in the US using T-Mobile USA, where I know they have H+. Can anyone tell me which modem I should use?

It won't matter which modem you use.
You'll only get HSPA+ in SOME markets on T-mobile in the US on this phone. The majority of their network only uses the AWS band for H+, which this phone doesn't receive one of the two required frequencies.
They have been re-farming the 1900mhz band (which this phone DOES receive) for H+, but that has only happened in a relatively small number of markets.
Try to set your phone on AT&T, maybe that network will do better.

He meant to ditch the T-mobile SIM, and get one for AT&T. The phone gets H+ on all of AT&T's network.
I want to Enable H+ but i don't now how.
Is it only available in selected providers, Countries or everywhere? Or just in Big Cities ?
( More Infos in my Profile )

If you enabled WDCMA in network options, phone will automatically use H+ when carrier and current station supports it.
I recently have two Galaxy S III phones with two providers T-Mobile and Vodafone. With Vadofone i have H+ but my T-Mobile only gives 3g. It depends what your provider gives you.
