I have been flashing for years and i just came over from ATT SG3 where i had no problems flashing and retaining 4g, but now on tmobile every rom i flash all i ever get is 3g and never 4g .. only for a brief second. the reason i came from ATT was the unlimited data.. can someone please assist as i used CM10, AOKP, WICKEDv5, blackjelly..... i cant figured it out. any help would be appreciated.

Hmm i would think Phoenix should have good service. Maybe you should Odin back to stock and start all over. Radio is the only reason i can think of that would affect the speed.

How are you distinguishing what connection you are on? Many roms will show H+ instead of 4g

I'm on stock. Rooted yesterday and download speeds seem slower now. I will do more testing this afternoon.

well on the t-mobile variations the best you can get is H+ and most ROMs show that. other than that, try using a different kernel. that was the problem for me where my data wouldn't even work sometimes.
It looks like op knows the difference between 3g and 4g/H+ he noticed that he only gets 4g for like a second here and there and that's it.

I had a similar problem. What happened with me was one day I went from great 4G (HSPA+) speeds 80ms Ping, 25MB Down, 4MB Up to all of the sudden a 1200ms Ping with 0.05MB Down and NO UPLOAD.
Turns out it was a problem with some towers in my area. Took T-Mobile two weeks to fix everything. Not sure if that is what's happening here but it could be possible.

Same issue AOKP Build5 4.2.2
I too have this same issue with AOKP build 5 solid 3g but no 4g (H+) (tmo)
Stock however has solid 4g (chandler AZ)
gonna try CM and see what happens there.
Also gonna research radios aswell (really really really liked AOKP just didnt like being back on 3g)

I signed up with tmobile about two weeks ago and have had no complaints until now. All of a sudden I am having trouble keeping a constant data connection at my place of business. Idk if its my phone or a problem with the local tower but the signal is all over the place while browsing the web. It looks like a strong signal until I go to use data then it drops to nothing. Last week this wasn't a problem at all.
Any tweeks or hardware I can buy to help remedy this?
My phone is completely stock and I am on the 30/month pre paid plan if that makes a difference.
Are there any better radios out that can be installed maybe?

Is WIFI available at your place of business? If you are completely stock I'm assuming you are on GB. If that is the case use the WIFI calling feature offered by T-Mobile. If WIfI is not availiable you can try flashing the Blaze modem it improved my data speeds.

Unfortunately WiFi is not available. I will look onto flashing the blaze modem. Thanks!
If ICS is indeed right around the corner will it come with different modems?

Well hopefully it is right around the corner and we can have the current crop of ICS roms rebased off the T-Mobile S2 stock build and not from our distant cousin AT&T SkyRocket's build. But to be honest I’m not sure if it will or will not but I’m assuming it will as the current set of radios needed to be tweaked to work on current ICS roms. Any who if you want Mr. X has a list of some radios that he has tried and reported working he listed radios for both GB & ICS which I will post a link to his thread below. Try them out and you might just find one that works for you.

I called tmobile about what was going on. They said they were going to try to reset my data connection and that I should reboot my phone and of its not fixed in a couple hours then to call them back.
I did this and all is well again! I'm back to a good signal and have not had any data issues in the past couple hours!
Thanks for all your help though it was greatly appreciated!

Anyone seeing a problem with data speeds dropping on 8-30-2012 Aokp JB rom on their AT&T Galaxy S3. Mine was 10mbps dn & 2mbps up...now its throttled at 4mbps & 1dn. Checked against my wifes GS3 & its still getting the 10mbps. Tried flashing back to LG1 modem but no luck??
Yeah I got it too. Wasn't sure if it was just my area that was sucking after Isaac hit us.

Yea i tried to go change mobile settings to lte but still had the drop occuring. Flashed back nandroid of Ultimatum 1.3 & all is fine again. Do you know where the latest on the 9.2.2012 task650 AOKP JB is ...was wondering if maybe this was resolved cause i sure love the speed & customization of his rom! JB Rockz!
During Isaac we lost data atleast 4x a day while I was on Aokp. I went to stock it was fine .

I don't know how it is for AT&T, but AOSP ROMs on the T-Mobile S3 cannot properly utilize HSPA+42 speeds either, so we have lower DL/UL speeds as well. Probably the case here.

ok so on these jellybean roms, my messages never send half the time even when i have full data bars or signal bars also my data always jumps back and forth between 3g and hspa and i know for a fact im in hspa region cause on a ics rom it says 4g all the time this sh*%$ getting annoying anyone know why it does this only on jellybean roms, is it cause the source code isnt fully available or something

Find a jellybean radio and flash it, should fix your problem. There is a couple threads on radio's in development section.
Hi, I'm currently using a cm10 rom and I flashed the UVLH radio. JB works smoothly for me and calls are clear and messages arrive lromptly even. Maybe just flash a new radio one that's okay for ICS

There is NO JB radio. 3G and 4G are almost the same thing. I do not believe T-Mobile phones with 4G can acquire 4G, as our 4G is a fake 4G. It is more a 3.5G. So I believe that it is just that the system recognizes the signal as 3G, but is really 4G.

Having really tough time with my SGIII. After rooting stock ROM and even after update to the latest JB leak from Sprint together with radio updates I am still getting really atrocious 3G speeds.
I am usually getting 50K both ways at best in Boston of all places. Any tips how I should troubleshoot?

Is your s3 set to cdma only or lte/cdma
I have not tested it on the s3 but I caught a bug on the evo lte where it was connecting to the new enhanced 3g (not actIve yet)
On the evo it would only connect properly if on cdma only.
You may need the app "network" to further mess with it

Why is it that I only flip between 4G and Edge but have no 3G. Does anyone else have this or is it a t mobile network thing?

It depends...are you stock, rooted stock, or custom ROM? The reason I ask (regardless of settings) is I never got 3G on stock. After I rooted and used Kasper's AOKP nightlies my phone would use Edege, G, 3G, and 4G. Where I work the signal wasn't so good so locking onto 3G was tough but with the J4 and JA modems now I can consistently hold 3G with the AOKP ROM.
My opinion is to check for the newest modem which is JA (Jelly Bean update) if you are rooted and use that from the modem download thread here on XDA. If you aren't rooted wait for the upgrade and you will get that modem regardless.
However, AOKP ROM most likely works differently so you still might not see 3G if you are stock JB that's why I think we would needa bit more info.
I'm stock everything for a change lol. I also have the latest jelly bean update. I haven't seen 3G once on the phone since I've gotten it. It's really weird...
Sent from my SGH-T999 using xda app-developers app
Your second guess is correct. Tmo is edge or a highly evolved version of 3g. It has nothing to do with stock vs rooted. The modem or kernel may help a little depending on what you are running. If you are in high speed 3g area aka 4G be happy.
Yeh it just gets annoying when I drop straight from 4G to Edge. :what:

T-Mobile uses HSPA+ for their current 4G network, which is just an extension of their 3G network. So, if you're on stock, it will jump from Edge to 4G, since T-Mobile's 3G and 4G are of the same technology.
When you're rooted, it will show 3G while your phone is at rest. As soon as "heavy" loads come in, it will shoot straight 4G. At times of very light loads, your phone might stay on 3G, but it's rare.
Bottom line, you're phone is perfectly fine when it jumps from 4G to Edge. Stock won't differentiate the two (3G&4G).
Well described... Thanks for clearing that up. Hopefully it helped some other people also.
