[Q] International Galaxy S3 isn't able to connect to Etisalat.af 3g data service

Hi. I'm here in Herat (Afghanistan) and I've bought an ETISALAT.af sim card that is supposed to provide also the 3g data connection. I've an International Galaxy S3 with Omega ROM v27 (4.1.1 JB) obviously rooted with Kernel 3.0.31-204919 and XXDLIB. the problem is that the smartphone is able to connect to ETISALAT 3g network (that sent to me also config sms) but it doesn't recognize the data network (no 3g, H or anything else near the signal bars). I've tried to solve changin APN but the result is the same. could you please help me.
Thanks in advance for your efforts.

Thank you for your answer. I have already tried this and I've also reverted to Omega v13 ( Ics based) wich have a different modem.
Hi cp108,
I had the same problem when I install the Omega ROM v27.1(Modem XXDLIB : same modem that your device has) on my Samsung Galaxy S3 i9300. Then I changed the access point name settings and data connection turned on. Have you changed following attributes?
1. Name
2. APN
3. Proxy
4. Port
5. MCC
6. MNC
7. Authentication type
8. APN type
In my case, after I changing above the problem solved.

[need help] WT19i reboots when switching to 2G/GSM network

I'm currently facing a problem with my WT19i, it reboots when it's connecting to 2G network. It happens when i set it to auto 2G/3G mode and it lost 3G signal then trying to connect to 2G, or i set it to 2G only. I've tried stock rom and kernel, several custom roms and kernels as well as reflashing baseband, but can't solve the problem. SIM card is working fine on 2G mode on my ST27i. There's a similar thread but with no solution.
Any help is appreciated. Thanks.

Weird Network related issue. Please HELP !!!!!!!!!!!!!! :|

I have been facing a weird issue for a while, in my rn3 snapdragon,
when i try to call to some of the numbers. from my jio network the call never connects, i.e. it ends instantly.
I am able to call other nos. from my jio sim, so i guess volte is working fine, idk.
I think its some firmware related issue, coz facing this in every rom even in MIUI
PS: its not a network or sim related issue, coz i have checked the same sim in other mobile, and i was able to call those nos. perfectly.
Also, i can receive calls from those nos. which i m not able to call
I can't able to find solution anywhere. Please HELP!!!!!!!!!!!!!!
Any help/ solution will be appreciated.
Thanks in advance
Facing this issue for almost 5 months now, and can't able to resolve it, flashed various firmware both by fastboot and recovery, flashed various Rom both stock and custom, also tried miflash & QFiL
