You're on the previous modem still, the latest ends in a "C."
Are you noticing any patterns with the connection problem? Is it only happening in certain places or when running certain apps?
I was having a similar issue but I was using the latest modem and it turned out T-Mobile pushed out the new modem before actually prepping the towers to connect to it in my work area.
Have you tried speaking to a tech rep and go over the coverage map with you?

There is no pattern it just randomly looses signal to like 1 bar and if I go inside a building it will 9/10 loose signal. It doesnt matter how big the building is. Is the modem in the dev section?

Charlie linked you to the latest modem. If you are still having problems after that you can visit Doc's thread in the dev section and experiment with the modems until you find the one with the best result for you, its stickied so you can't miss it.

Again thanks Charlie and everyone else for your help. Oh and read about your Rom and it looks great. I'm gonna try it soon.

Exactly why can't aosp ROMs update PRLs?

I'm running the lovely Jellybro ROM on my awesome GS3. I'm used to running aosp based ROMs and I do know that I can't update PRLs so I just nand my gettup and flash a tw ROM to do it. But my question is why exactly can't we do it? I heard that CM tried it before and it didn't work out? I tried searching for a specific answer and couldn't find anything...

UMTS on Frosty JB v11.2.1 rom

Did a search and didn't notice anyone else with this problem. Ever since I flashed Frosty I noticed that im stuck UMTS 3 and never switch to HSPAP. Wondering if there was something I missed.
And yes I did a clean flash.
Anyone else have this issue and is there a fix?

Not sure this helps but I seem to be also stuck. I am using frosty with stock kernel and canadian variant baseband. I don't know enough about these things to even know what the difference is but its something I will investigate next couple of days to see if it does switch.
You have your network mode set to auto ?

Try going into the settings themselves and actually manually setting it to HSPAP.

Could it be because I went from stock ICS to a stock, but rooted JB update and then straight to Frosty? My basebamd still says UVLJ4; instead of UVLJA, so I might have missed something?

Cool. I used to live in Miami. Gorgeous in the winter but so hot in the summer I had to put up the top on my convertible and run the AC just not to sweat.

Because of all the threads popping up for LTE it has become necessary to put them all in one place.

Although generally PRL updates will not help your coverage XXX13 adds several Band Class 10 (800mhz) SIDs for certain areas including Atlanta, California and Texas. These were not in any previous PRLs as they were the previous Nextel bands. Anyone in the affected areas will definitely benefit from this update.
