Voice Call issue in custom rom - Lenovo P2 Questions & Answers

I'm currently using Pixel Experience ROM (Android 9) and have tried Lineage OS 16 and bootleggers ROMs.
The issue that I'm facing is that, the SIM card is unable to send or receive voice calls (specifically Airtel and Idea), but Jio is having no issues. Funny thing is mobile data works fine for all the above mentioned carriers. This situation is for the SIM slot 1.
Even though SIM 2 slot only supports 3G/2G, Idea and Airtel 4G with voice call services works just fine.
Can someone suggest or share their own experiences.
Thanks!!!

SIM2 Not Working

Hi all,
Just got my Zenfone 2 yesterday and was super stoked, however the SIM2 component is not working. I have two SIM cards, one with Telus and one with Virgin Mobile. (Canadian carriers). No matter which order I put them in, the SIM2 card never works. The Zenfone 2 is able to identify the phone number associated with the SIM card in the SIM2 slot, but it is unable to actually make a network connection.
Anyone know how to get SIM2 working?
just update to the latest rom... I did and got my Sim1 working again!!

SIM2 is 2g only. So it needs to be Rogers (or network that uses Rogers) to work

Only SIM card slot 1 can access 3G/4G/LTE data. SIM card slot 2 can only be used for 2G service which include voice and basic text messaging (Not multimedia messaging services MMS or internet browsing). http://www.asus.com/us/Phones/ZenFone_2_ZE551ML/HelpDesk_knowledge/

I know this is an old thread but i was wondering if anyone has found a solution to this issue? I am having the same issue trying to get Sim2 to recognize a network. The number on the Sim card is recognized. I have tried switching the cards around and the result is always the same. Both providers that I am with are in Canada. One sim is with Bell and the second is with Virgin Mobile.
Are you saying you can't even make calls on sim2?

Cannot send or recieve SMS from JIO SIM (An indian carrier with LTE only network).

Hi everyone I was using LineageOS 17.1
I have 2 sim cards: One from JIO, a 4g only carrier and another from Vi (Vodafone) which has 2G/3G/4G. I flashed Lineageos first more than a year ago and everything was fine. But sometime around april this year SMS stopped working just for the JIO sim. Calling and Data work fine. I am not sure but i think I updated(17.1 -> 17.1) before this happened. Today i finally decided to investigate this. I tried the JIO SIM on another android phone as well as an iPhone and it works fine. but on my OP3T, it refuses to receive or send SMS. The Vi SIM doesn't seem to have any issues.
Another interesting sidenote is that if i remove the sim from the iPhone and put it in the OP3T, it doesn't work until i reboot the OP3T!
I tried updating to 18.1 today. It didn't solve the Issue. So currently I am on 18.1
Can someone help me figure out what the problem is?
