Check under status, does it show your IMEI or does it say unknown

Vibe X3a40 No IMEI and No Sim signal

Hi guys,
I'm new to XDA so sorry if i have missed any thread on this, but i did search on this and got nothing. That's why i'm posting here.
I got into a bootloop in my vibe x3 and had flashed stock ROM for x3a40.
After flashing there is no IMEI number and also the sim card signals are not getting detected but the sim is getting detected.
Example: No Service - Jio.
Tried other sim cards, the same issue persists. Tried the sim cards in other phones and they work.
I'm guessing its because i flashed a stock rom.
Please guide me how to get back the IMEI number or atleast to get the signals detected as this is my primary phone.
Thanks in advance.

Is there an IMEI number showing in settings?
Yes It Shows IMEI number and 2G and 3G networks can able to connect ,but the problem is only with 4G ..so 4G networks are not detected if I do manual search of network then also same problem remains..Device only detect 2G and 3G network

S8+ sim card detected but not working after flashing custom ROM.

Hi ,
I recently flashed my Galaxy S8+ with Hades ROM which is a ONE UI based ROM .
Everything works fine but sim card is not getting any signal or just shows " not registered on network" sometimes.
But it do work sometimes when connected to WiFi n when WiFi calling is enabled , but I can't use my mobile data or calls from my carrier network.
THE PHONE BASICALLY HAS FEW ISSUES BEFORE FLASHING NEW ROM .
1 ) It was bought from UAE and it was already rooted when I got it .
2) Attempt to flash stock ROM failed everytime cz the SIM card was not detected even when it was in stock ROM itself.
3) so many try with different versions of Odin and different versions of Stock firmware , it did not work .
Please give me some fix .
(NOTE) : SIM card is working very fine but the issue is with the phone itself.
What is so "secret" about this topic, that no one of the experts likes to talk abaout it and help us out? So many have this problem. Even though for those like me who have a stock backup auf EFS and Baseband. If somebody would be so kind to send a pn with further hints would be very kindful. Thanks a lot folks.
I had the same problem after flashing the stock ROM, but i just can't find help with this problem.
I gave up and bought a new phone.
