Galaxy S II Skyrocket on Tmobile 3g?

Hi, I have been reading some posts in the Radio thread reporting that they are using the T-mobile Modem. It was unclear whether they had it working on the T-mobile network or just using the modem on the ATT network.
Is there anyone here using the Galaxy S II Skyrocket on T-mobiles 1700Mhz AWS 3G band and getting internet and sms and everything no problem?
I just want to make sure before I go out and purchase one for a lot of money and not have it working.

Yup I believe that the Skyrocket and the TMO SII are the same phone or at least have the same radio

Yes, you can use the t-mobile modem on the skyrocket and connect to t-mobile 3g. There are people on xda that have done this and confirmed working. The modem chipsets are different though.
There is one thing though. The skyrocket modem (mdm9200) supports 700/1700/2100 on LTE which is the same frequency that t-mobile uses on 3G. My concern is that although it will work since it is the same frequency, the skyrocket modem uses the 700/1700 band for LTE and not 3G, but 2100 for 3G and LTE. The t-mobile sgs2 uses the mdm8220 which supports 1700/2100 for 3G. I don't know enough about the particular power/design differences to say if this is a safe thing to do for extended periods of time. I heard of a few people having problems with their modems after flashing tmob modem on their skyrocket. Don't know if it's connected to the hardware differences.. just a caution. Make sure you have warranty or insurance coverage before you try

I'm going to buy the phone secondhand and thus I will not have warranty or any return policy hence I am worried. I wanted to make sure that it works before I go out and purchase the phone.
Were the people having problems the people who were still on the ATT network? I plan on using the phone strictly on the T-mobile network which I hear is also going to be putting out 1900Mhz 3G in certain markets due to the failed ATT merger and I happen to be in one of those large markets.

I have seen this question more than once but never an answer to why...with the two phones being nearly identical, what is the draw causing some tmo users to want the 727 over the 989?

Around here it is cheaper and also I hope that the phone will work with non-smartphone data plans on T-mobile because T-mobile locks out their own smartphones to certain data plans.

As I've said, others have reported it to be working. However, I don't think there are enough people doing this to give a clear idea if the tmob modem is having any adverse effects on the skyrocket modem. Maybe open a poll thread to get a better idea?

One of my customers came in with an unlocked and rooted sky rocket, any idea as to how to get it off our edge?

This is for everyone.
IT HAS TO RUN A TMOBILE SGS II MODEM. The radio has the capability, but the modem.bin for the SR doesn't activate AWS/2100. Flashing a T-Mobile modem will fix that though.

Just beware of the sbl.bin (Boot Loader). Do NOT flash the sbl for the Hercules on the Skyrocket. Everything else appears to function the same.
(I've been researching if I should get a Skyrocket or Hercules)

Should i buy a t-mobile branded Galaxy S II or the AT&T branded Skyrocket

The title says it all im really not sure which one. I have T-Mobile but i can get the AT&T skyrocket now for a little bit cheaper than the T-mobile Galaxy S II. My problem is that i am not down to lose my HSPA+ speeds with T-mobile. Because the phone will be AT&T and not T-mobile. But I do know that the skyrocket does indeed have the T-mobile HSPA+ speeds. I am fairily android savvy so i can most likely figure out all that stuff you know? But if I do go the AT&T route does the phone work flawlessly just like it would as if I had the T-mobile version? Or will battery life take a hit? etc?

i vote att. i like them
Sent from my SAMSUNG-SGH-I727 using xda premium

Wait what? You like tmo but want skyrocket. But like tmo phone but not skyrocket. Id just get the carrier specfic device. Sometimes running different phones on carriers doesn't always work out of box.... you might run into bigger issuses if you ever lost or damaged your phone too.

I have T-mobile and I will be keeping them. Butttt I want to get the Skyrocket because its cheaper lol. And i dont care about losing or any of that

Skyrocket gets about 3g speeds...not 4g. If you're out of contract with TMobile you could try straight talk for 45 per month. Consistent 3g speed.

i have a skyrocket i727 and I am on Tzones for Tmo ($5 internet).
Works flawlessly, great speeds, haven't found many holes in reception. Problem is heating, and battery life. If you are paying for the full prefferred internet plan, i would definitely get the t989

Thank you for the input but it is slightly false and wrong the skyrocket would receive 4G speeds because all of T-Mobiles stuff is the same

Ohhhhh so I wouldn't be able to downgrade to the T-Zones? And yeah I heard that the battery drain is drastic and the phone runs hot. I just went ahead and got the T-Mobile variant

Both you would use on At&t?
Would you be using either the t-mobile or the att version on the at&t network unlocked?

About to get Nexus S for Tmobile.

so im coming from a HTC Radar. what things will i miss? and is the gsm version for tmobile? do i have to unlock or anything?

Model I9020T is the T-mobile version that runs on T-mobile 3g and edge network no unlock required phone comes unlocked out of the box!

You'll miss the 4G and 720P recording. Other than that both phones have about the same capabilities. It's pretty easy to unlock the Nexus S.

You'll miss Zune, thats it. Everything else is a plus.

hows battery life?
since no 720, hows the video and picture recording?
and should the other person im trading wiht put extra money in?

Battery life is excellent!
Video is 720x480 (Standard DVD quality)
It's hard to say about the extra money. Maybe an extra $50 (to you that is).

For a Radar? You should be paying to get rid of that thing.

If you just want to use Wifi/Using it as a normal phone, you will be fine with a i9020a. But if you want data 2G is really slow and to the point of unusable.

I remember a time not long ago when I would have thought 2G speed was fast for a home internet connection. Now people find it unacceptable for nearly anything. Wonderful as technology's rapid advancement is, it sure has made people impatient.

What combination is suggested to get T-Mobile 4G on the East Coast?

As the title says! Now by combo im referring to ROM + RADIO + KERNEL!
A good example would be tspx23's [Combination juggernaut 4.1/faux kernel NOT overclocked/KL1 Radio] which gets 4G on the West Coast.
The phones been out for a while so i'm just trying to gather info before I buy the phone tomorrow. Thanks again!

Not to be daft, but if you're going on T-Mobile why are you bothering with a Skyrocket? Yes I know you can get it to work on T-Mobile, but unless you're getting a SPECTACULAR deal on an unlocked Skyrocket or you absolutely need a SD Card, why not just get the Galaxy Nexus? It has a better screen, nicer physical profile (IMO) and it's the current flagship Google device, meaning you'll get all the updates before everyone else, not to mention it's only $350 and a truly global phone. My wife has it on a monthly 4G plan and at times I get jealous of it (except for the times when she has an Edge connection while I have HSPA+, but that's a carrier issue, not a device one.)
Just throwing that out there..

I'm already on T-Mobile but could only find a good deal on a Skyrocket sadly. I already got it not i need to do all the mods and what not.

Should just be as easy as flashing the blaze radio from the development thread. All roms should work, including the stock ROM. Flash the recommended kernel for that ROM, hint use ones the Dev told you works great. May have to configure the APN for TMobile if flashing the blaze radio didn't do it for you.

would you please share your average data speeds ? download and upload ? and how does it perform compaired to T mobile phones ?

ROM has no effect radio is dependant on your specific area
Kernel won't change things up for your data speed either

Basically if you have the OPTION on your OWN to pick depending on the server your on I would suggest getting the own for your service like if you on AT&T go get the i727 if your on T-Mobile get the S2 cause the chances are your speeds are going to be best using the phone made for the server you have chosen. ME on the other hand had LIMITED option due to circumstances I was offered to be on sprint with a parent but was cut off half way of summer so i go back to my original parent who originally took me in T-Mobile and was stuck with a sprint phone the "Motorola Photon 4G" which thanks to a dev on XDA was allowed to unlock the SIM slot for DOMESTIC GSM (USA) with that in mind i liked it but data speeds were sad so i grabbed the i727 and unlocked it so here i am. I will give you output on the speeds once i find stable Combination.

I know that....I would all day anyday use a T mobile phone with T mobile or an AT&T phone with AT&T...especially with these sophisticated devices...I always see here people unlocked their skyrockets fine, flashed TMobile radios and report crappy data speeds and awful coverage...So I'm asking if anybody did use t mobile with skyrocket and data working fine (no crappy download or upload speeds)

I can't get a decent 4g download speed either. I'm currently on Embryo 5.1 and Kernel CYMBALINE-RD03-2.6. I've tested most of the radio that have been posted and still only getting around 550kbps dl and 25kbps ul on all of the radios. Getting over 10Mbps dl and ul on a tmobile phone next to it. Maybe my settings are wrong or something, but I've dial *#2263# and forced it to WDCMA 1700.

does anybody have GPS issues with lack of accuracy and long time to lock? i've never had good GPS performance with the skyrocket on tmobile radios. (i never ran this phone on att network and att radio, so i do not know if GPS performance is any good on ATT radio)

No 4g, worth even buying the S III or should I wait?

I live in Omaha NE, and we still have yet to actually have 4g access. Anyone in an area without 4g have the Galaxy S III and still recommend it?

I sometimes go in spots where there is only 3g.Coming from my x2, even when only in 3g the s3 is faster and smoother then my old 3g phone, but everything is evidently gonna be 4g so you can't go wrong it's a nice phone.

When you say 4g, do you mean hspa+ or lte?
I live in an area with no lte, I get respectable hspa+ speeds. If you have no hspa or lte, then I find that surprising. I thought at&t set out to cover areas lacking hspa with LTE first. Thats why cities like Philadelphia just got LTE today.
Anyway i recommend getting the s3. Its the best LTE phone out by far and eventually at&t will cover you with LTE.

As it has been stated above...4g or no 4g this is (imo) the best phone out there.
I live in a non-4g area and I love the phone. I figure that whatever phone I get is only gonna be 3g (most of the time) so why not buy the best.
Plus it's like a bonus treat when I travel to a city with 4g and I see the little 4g icon pop up...It's like a special gift form the city to me

This phone is a beast, 4G or not. The processor, RAM, screen, functionality, development choices, and style are just a few things that should sway you toward buying this. Wait for what? I doubt anything can be better than the GS3 for another year.

Apple confused the hell out of everyone on the 4S. I frequently talk to people with the iPhoney that think they have 4G service. Also heard of an IPOD nano coming out that is labeled 5G? or something like that. I just wish they would continue to avoid 4G service and dread the day Apple users suck up all the 4G bandwidth.

SGS3 is an awesome phone, whether you are on 3G/4G-LTE it's going to kick your old phone to the curb. The phone is faster so I could possibly pull better speeds even on 3G than your current handset. If you travel at all you'll be 4G/LTE ready and when you finally get updated locally you'll see awesome immediately.
There is also huge support for the SGS3 because of the bootloader getting unlocked a few weeks back and of course because it's just such an awesome phone period.
