I have a GT- i9100 with a 4G plan (HSPA+). The problem is that I cannot get it to work on any non-stock rom. I have tried at least six stock roms and it has worked on each one. But whether aosp/aokp/miui, I can not use my data connection for internet. I have manually entered and double checked apn settings many times. I have enabled hsdpa etc under Galaxy/ Advanced settings and restarted many times. I have tried numerous modems to no avail. My phone is rooted but not unlocked. I am not sure if that is relevant. Help would be greatly appreciated.

dial *#*#4636*#*# to enter device mode.
Change your radio to LTE.
Tell me if it works

Tried to enter four times. Every time got the following message
"Connection problem or invalid MMI code."

Sorry, I made mistake while typing the code the other time.
-Dial *#*#4636#*#*
-open phone information
-set radio to the band of your choice.

Good luck

I'm also interested on activating H+ on non-stock roms. I really hope you'll find a solution.

You are technically correct but in some countries, H+ is referred to as 4G.

In my country, H+ is referred to as 3.75G

HSPA+ does work on non-stock roms, but the icon showed only H, and not H+.... There has been a recent patch submitted, approved and merged in aosp roms.... Update to latest nightly if you are on aosp.... To confirm, go to settings, about phone, and then status...

Recently, my carrier upgraded to H+ and it works fine for me on Aosp ROM.

I contacted him brought up this info again because i promised to help him when i find the solution and i think I've found it.

Just waiting for his response
