Probam Custom Rom stuck on 3g - T-Mobile, Samsung Galaxy SIII

I recently downloaded the probam 4.3.1 t-mobile jellybean custom Rom. Everything is working fine except that I can never get 4g or H+. On stock I was always on 4g and never dropped down to 3g. Also when I had dandroid T-Mobile custom Rom I would be on H+. For some reason probam only allows me to get 3g or occasionally H. I have a Wind Samsung galaxy s3 SGH-T999V.

Download the speedtest.net app from Google play, run it and check the icon in the statusbar, does it switch to H or stay at 3g?

When I ran the speedtest.net it changed to H. Still not the 4g or H+ I'm looking for.

You won't get 4g. That's what T-Mobile roms show regardless of whether you're on H, or H+. Sounds like it's functioning normal to me.

Whoops hit the thanks button.
On custom roms like probam, the phone will switch to 3g if no data is being used and back to H when data is being used.

3G 4G LTE

Does anyone know how I can change the network? Most of the jelly bean roms don't have 4G I'm on 3G with the dragon rom. Anyway where would I go to change this? In the build prop? I know some say change modem but that has nothing to do with it. Any help would be great.

You would think it could be changed in the build. I have been looking through the build prop but just not sure if that's the right place to start or not. Has to be a way to re write it.

Change the network? It's determined by the Access Point Names and the Network Mode. If you're accessing an LTE-capable APN then as long as you're Network Mode is set to LTE/GSM/WCDMA (and your in an LTE area and have LTE provisioning on your plan of course) you're phone will access it if it's the strongest signal for you.
1 bar of LTE is way faster than HSPA+ btw

Do you have 3G or Hspa+ because on the stock roms it says you have 4G but it really isnt , it is Hspa+.

Have you actually ran a speedtest to determine your actual network speed?
I did a speed test and u get like 23mb download but that's included with my build.prop tweaks
Sent from my Desire HD using xda app-developers app
You can Change the apn right then add z few modification to build.prop then you should have better faster network speeds in theory

So how do I set my Network Mode? My S1 (I9000) has a 'network mode' setting under 'mobile network settings'. It lets me choose between GSM, WCDMA, or both (auto). My S3 has no such setting or option. By the way, the I9000 always worked better in WCDMA Only mode.
I am on a Straight talk plan and have no access to 4G network.

After Jb OTA am getting 4G in status bar when Orange needs 3 years to provide it!

How could this happen!! My phone is a T-Mobile T999 unlocked and working on Jordanian Orange. According to orange they will begin providing 4g in 2015 yet in status bar I see that am connected to 4g. Could the T-Mobile build be exaggerating figures ??

Mine always shows 4g...Although truly I am not always connected to 4g.
Just run a speed test and you will see.

Most phones would show H or H+. The T999 was coded to show 4G instead, in keeping with their ad campaign.
If you go into settings, about device, status, under network type itll say UMTS at idle and probably HSPAP when under load.

No LTE CM10 Telus Galaxy S3 Please help!!

Hey everyone,
I just flashed CM10 on my Telus Galaxy S3, but when I try to do a speed test, i get fairly slow speeds and instead of showing the LTE icon, it shows the HSPA+ icon. Could someone please tell me how I can get LTE back?
Thanks so much, and any help is appreciated
If you go to System Settings > More Settings > Mobile Networks, is the Network Mode set to GSM/HSPA/LTE (Auto Mode)?
There is no lte icon on cm10
It will show as 4g

Did you make sure that your APN settings are correct? If not, look around on the forum, actually here:
http://forum.xda-developers.com/showthread.php?t=1977232
And once that is done, make sure you click on the menu button to "save" your settings, then reboot.
If that doesn't work, don't know what it could be!

Cm10.1 data switching issue

When I turn on my data it switches between 3g and 4g and I can't even figure it out
Sent from my SGH-T999 using xda app-developers app
That is how it is supposed to work, nothing to figure out.
My gfs phones never switches or anything my phones does all the time
Sent from my SGH-T999 using xda app-developers app
What is she on and it never switches to what? If she hasn't updated her modem it will stay on 3g all the time. It is like this on every AOSP rom for our phone. Unless there is a theme that edits it out.
If speedtest says it's fine, it's fine.
It just switches from 4g to 3g all the time but I guess I'll have to live with it

Slow speeds? Poor reception?

Recently came from the lg optimus g to this. When I had the G it consistently ran on 4g lte speeds of 15-18 , even saw 21 mbps download ....now on this its rarely above 3/5 bars and hd on youtube takes ages to load...normally id think att docked my speed because im over 5gbs but ive only had this device since sunday and todays the 5th .
Whats going on?
Edit: my galaxy is 100% stock
Stock rom, not rooted, everything stock

Check your apn settings. If it is set to pta, switch to phone.
