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

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.

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

Its how its suppose to work. H shows when cell data is accessed and when idle it shows 3g... Not sure why it bugs some people.

Bad reception

My gs3 has been getting bad reception lately. My gf's HTC 1x and my gs3 used to get about the same service inside my house where now I'm getting 1 bar when she gets 4. I've tried everything I can think of to get a better signal. Flashed modems, changed apns, flashed back to stock, tried build prop hacks, nothing helped. Could this be an antenna malfunction? Are there any hardware mods that may help? Maybe something I've looked over. Any help would be greatly appreciated.

Been having the same problems, always at 1 bar at my house, WiFi on makes it worse for some reason..
Sent from my SAMSUNG-SGH-I747 using xda app-developers app

I just turned wifi off and went from none to 2 bars. But with the way my signal goes in and out it could just be coincidence........

Here is a list for different radios on i747: http://forum.xda-developers.com/showthread.php?t=1831898
You can flash them in twrp or cwm.
Its a hit or miss depending on your phone and area.
I tried the latest release and am getting very good reception
Sent from my SAMSUNG-SGH-I747 using xda app-developers app

Didnt realize they had a new radio. Really wasn't expecting the new radio to help since I tried the rest with no success but it actually fixed my issue I'm getting about the same service as my gf. Thanks alot.

Probam Custom Rom stuck on 3g

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.

Gapps don't work on LTE

I have flash cm 10.2 several time fresh install every time. I followed the op to the T, even went back to stock and started over again a couple of times. Tried a different ROM and still getting the same issue. I flashed the modem in cm 10.2 thread but the play store and Google now won't work on LTE. It works on H+ fine I googled it and can't find anyone else with the same problem. I even flashed different 4.3 gapps. Please help

APN settings for your carrier correct? Does LTE work for other apps?
Sent from my LG-E980 using xda app-developers app

Yes every thing else works
Sent from my LG-E980 using xda app-developers app

Maybe you don't have LTE in your area. The 4G displayed on LG stock is actually only H+ unless it says 4G LTE.
