Issue with mobile data on nubia z9 mini

Hi,
i recently installed Chinese rom of Android 5.1.1 on my nubia z9 mini indian device.
Most of the things work fine so far only issue I have is one with mobile data.
I'm not able to get mobile data working.
Network gets selected fine but internet does not work.
I have read multiple threads and looks like this is known issue. Someone did mention that he found solution but I did not find link to his ROM.
I want to know how to fix this issue.
APN is correctly set.
Thanks,

Network Issues on my k3 note

Hello guys..
I am a K3 note user and I have been facing network related problems with my phone after a few months of purchase.
I am using Airtel 4G sim card that works fine on other mobiles but not on my phone. I tried using other sim cards , but no network at all. The phone becomes quite warm when there is no signal. I was on stock ROM before and now I am using a custom ROM( Resurrection) to see if I can get my problem solved.
I tried all possible fixes and solutions that I found over the internet, but yet no result.
Please!!! can someone help me resolve this issue because I have a phone that cannot perform this basic task.
If there are issues with the hardware, how do I check that?
Or is there any patch or build prop edits for this issue?? Please share....
Thanks in Advance...

Its very simple..
First I installed custom recovery(TWRP 3.0) using sp flash tool. Then i downloaded ressurection rom and copied to my storage.
Using TWRP I took a backup of my current system(android 6.0) and wiped cache/data/system. Then i flashed the RR Rom zip file from TWRP.

After installing K3 Note custom ROM lineage 14 on my A7000 Plus, no sim. Pls help

I tried installing on my a7000 plus a custom rom from K3 note because many people were saying that these are identical roms.
But I encountered a problem which I don't know how to fix. My baseband is gone(written "unknown"), no sim working and no IMEI. But Wi-Fi still works. Please healp me, I have been searching for almost 15 hours and I can't find anything!
