Unlocked phone but no 4g, please help - AT&T Samsung Galaxy S II SGH-I777

So I bought a new SGII 1777 for a really good deal. Brand new out of box, etc. Anyways, T-mobile is my carrier. I was able to root the phone and unlock it. The strange thing is that now that my T-mobile SIM card is in this AT&T phone, I am not getting 4g. I am only getting "E" coverage. I followed this guide http://forum.xda-developers.com/showthread.php?t=1286432. Am I missing something? Is it firmware? Kernel? currently, kernel in phone is 2.6.35.7 with Gingerbread.UCKH7. I'm in the US, so if any of this info helps my cause please assist. Any advice/help/suggestions are welcome. Thanks XDA!

Your on E and you will continue to be on E. The AT&T phone dosent support 3G/4G Tmo bands.

You won't get anything faster than Edge with an att phone on T-Mobile. Hardware is the cause.

The exception would be some of their LTE phones reflashed with a T-Mobile radio. Pretty much Skyrocket and Note and that's it.
This is because AT&T uses 1700 MHz for LTE and T-Mo uses it for 3G, and other than the radio firmware the T989 and Skyrocket are almost identical.
Right now, with the exception of the above cases and the international unlocked Galaxy Nexus (which is pentaband HSPA) - only T-Mobile USA phones will get 3G on T-Mo USA. There may be a small handful of other exceptions, but very few non-Tmo devices support 1700 MHz.

Some research could've prevented this. Or just buy the phone made for T-Mobile.

To answer your question the SGS II only works on Edge and not 3g for T-mobile.

Works fine on 3g for me!
I am also using T-Mobile with 3G (or Orange T-Mobile as it is now called in the UK).
I assume the guys that can't get it working are in the States?

the thread starter needs to title his thread "tmobile USA" because obviously this phone does not work with tmobile usa 3g. of course tmobile in europe will work fine.
Should have written my answer with more detail :/ The SGS II works for Orange in the UK but with T-mobile US it only works on Edge.

Hello. I have a GSII from UK, on T-Mobile. Tried to work with a guy at T-Mobile to figure out how to get 3G (only Edge now). My unit is rooted. I would love (and would pay!) to get 3G working on my phone. Can you help out?

If your on T-Mobile US, you can never get anything but EDGE.
Thanks for quick reply...
...not to be a pest, but does the phone I got (UK GSII) just totally lack the hardware capability to do 3G, or is it a software/firmware issue that may some day have a solution?

The UK GS2 lacks the current bands to run on T-mobile US network, since they use different bands compared to T-Mobile UK. If you want 3g/4g, you have to wait for T-mobile to release their variant in the states or otherwise change to AT&T.

Hey BostonBob... you might what to take a look at this thread. It explains the situation in a little more detail: http://forum.xda-developers.com/showthread.php?p=16356271
Short answer... it appears one-half (the upload half) of the TMobile USA 3G signal is at the wrong frequency (meaning this phone won't support it.)
I looked around to see if there's a software hack to reprogram the frequency or a hardware thing. Best I can tell...
1) The SGS2 supports a VERY wide range of frequencies. The i9100 service manual shows it clearly supports service in the 1700 MHz range... but not specifically AWS (Advanced Wireless Service) that TMobile USA uses.
2) The service manual actually shows you how to go in and 'fine tune' the frequencies if you have superhuman soldering skills.
3) Bad news, even if you hit the right frequency, I'd assume the antenna firmware would have to be changed (well outside of my area of expertise.)
I keep hoping that someone with some knowledge of programming one of these antennas will chime it, but no luck yet.
Now that TMobile USA is releasing their bastardized version of the SGS2, maybe we'll get lucky and the telephony portion of the hardware will be interchangeable (though I highly doubt it.)
If it's any consolation, I'm in the same boat.

ATT Galaxy S II - i9100 T-Mobile 3G/4G Network???

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.

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!

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.

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.

Galaxy S3 International works on Rogers?

Hi, I've read that the international quad core version of the Galaxy S3 can be used on Rogers.
I know absolutely nothing about phones so I was wondering how this can be done?
Do I just buy the international version without contract and take it to a Rogers service store and add a plan on it? What type of plan should I be using with the international version? I don't need LTE or 4G. I'm fine with the 3G network as long as the phone works without any issues. Is there any trustworthy sites where can I buy the unlocked international version of the S3?

From a little bit of research, everyone is saying the international GSIII will work as long as it's on a 3G data plan. Is there any downsides to using the international version other than being limited to 3G? Is it as simple as buying the unlocked GSIII int'l phone and using a 3G plan on it?

I don't think there is any downside apart from not being on LTE. Yes it should be as simple as buying an unlocked phone, putting the sim card in it with a 3G plan. In case if your data does not work check if APN is added. I remember it was added automatically for me on GSII
I'm on rogers with the 9300, works fine. Obviously no LTE, but the HSPA+ is fast enough. Not to mention Canadian bandwidth restrictions making LTE a huge turn-off for me. 6GB a month for $60+, no thanks
EDIT: I could be wrong but I don't see a problem with what you mentioned in the OP. Get the phone and just buy a regular smartphone data plan, or whichever plan you want. As for myself, I kept the same plan as my X10 and just cut my sim up because it wouldn't fit and it works fine, no change of plan or anything.

[Q] i9300 and Straight Talk

Any US owners of the i9300 (that's the non-US/International) version of the S3 using the Straight Talk service? I've been looking into them as a way to get some 3G data access for two weeks, but their customer service folks just replied saying that my S3 won't work because it's not a US model.
Looking at the specs seems to show that my S3 will support their frequencies, but I'm wondering if there's some kind of clever device block in place.

I'm using it, it works fine. You need to choose AT&T-Compatible SIM when you buy a SIM, otherwise most of the time they'll send you a T-Mobile SIM if you choose for them to pick it automatically. Also, this wouldn't affect whether or not you get 3G/HSPA+, but make sure when you fill in the APN, you don't fill in any proxy information except for MMS proxy.

Many thanks. :good: I think their CS folks are about as good as the ones for the carriers over here - since their emailed advice contradicts what the website says:
BRING AN AT&T OR T-MOBILE COMPATIBLE GSM PHONE, OR AN UNLOCKED GSM PHONE
Make sure it operates on our compatible frequencies (850 and 1900 MHz)

And according to http://www.samsung.com/uk/consumer/mobile-devices/smartphones/android/GT-I9300MBDBTU-spec the International (UK spec in my case) S3 supports "850 / 900 / 1900 / 2100".
Again, thanks for taking the time out to reply. Maybe see if I can use a local Walmart's click n' collect service to get the SIM+minutes card when I get over to Orlando.

Yes, you have to make sure the SIM card isn't for T-Mobile's network. Until recently Straight Talk was only offering this SIM, so your best bet would be to buy an AT&T compatible SIM from their website.

<rant> Verizon and att use different networks, that will never work, especially with a LOCKED phone. Also, this is the forum for the international s3 (i9300), not the verizon s3. </rant>
Pick up the straight talk activation kit, Verizon uses CDMA signal, not GSM.

The Verizon S3 supports GSM though (their LTE devices from the Rezound [2010 or 11] onwards do). Their LTE devices also come factory unlocked out of the box due to a deal that Verizon made with the FCC in order to be able to use the 750 MHz LTE spectrum. Long story short, Verizon LTE devices will get EDGE and HSPA+ (no LTE) on AT&T. It supports the same bands as the i9300.

[Q] T-Mobile, buying unlocked from HTC US

Weird,
I want to by HTC One to use with T-Mobile in USA, if I select unlocked version from HTC site:
HTC One® Unlocked (32Gb) says: The unlocked version does not support the 1700 band so HSPA+ and LTE will not work on the T-Mobile network.
http://shopamerica.htc.com/cell-phones/productdetail.htm?prId=41589
HTC One® Developer Edition (64GB) doen't say this.
http://shopamerica.htc.com/cell-phones/productdetail.htm?prId=41599
Is it safe to buy 64G for T-Mobile?
The problem is I can't buy from T-Mobile onlive steore, cos they sell only with a plan (even full-price version).
Thanks.
Make sure you live in area with 1900mhz bands reframed or tmobile lte otherwise you will be stuck with edge speeds

They have the same exact frequencies. HTC goofed up. Its in the forums bro. Anyhow, thing is T-mobile will work on AWS LTE band 4 1700. but not 4G which is hspa. If your in the area with 1900 coverage or LTE then your in luck. If not.. go on to a t-mobile store and get yourself a phone

That's stupid, how do I know my coverage frequency? I'm in Seattle area, sometimes I travel to LA.

LA has spotty 1900Mhz coverage on TMo. It's far, far better here with 1700Mhz. That's the exact reason why I bought the TMo version instead. If I need to unlock it, I'll either pay $20 on eBay for a code, or just pay for my device and get one from TMo instead. There isn't any branding on the phone at all, and you'd miss WiFi calling with the HTC store version.

Bro, if you got always "4G" on your last phone its not going to work on dev edition simply put. no 3g for you sir! if you got "LTE" or "H" on it then dev phone will work for you. if you always got just 4G.. welcome to Edge world on your dev phone.
I just put it to you in simple terms. Off you go Decide either the dev or t-mobile phone. Honestly, its looking like you gotta send that bad boy back and get a t-mobile one
Im in the same boat. I get E on HTC unlocked One, when I had 4G on my Tmobile One S unlocked. So, if I return the phone and get a T-Mobile version I should get 4G like I did with my old One S??

Yes.
That is crazy. I dont think that 1700 warning was there two weeks ago when I pre-ordered. Either way, where do I get a T-Mobile unlocked from now? Do I have to buy a regular T-Mobile outright then enter a unlock code? Thanks again.

It was there all along and everyone who did the research knew it won't get T-Mobile aws band. Your best bet is buying direct from T-Mobile and unlocking.

T-Mobile's branded phones always say "4G" when on HSPA+. International phones usually idle with "3G" and then change to "H" or "H+" while data is active. Neither of these things is an indication of what frequency your data is being transferred over.
That airportal site linked above seems pretty good; there are other crowdsourced options for finding the PCS refarmed areas, too. A good way to be safe if you're dead set on the developer edition is to wait for LTE to roll out in your area since that will definitely work.

You don't need an unlock code if you plan to use it on T-Mobile US (including prepaid MVNOs), only if you plan to use it on AT&T or internationally.
Dude call tmobile and you will be able to order via the phone
