    Hello,
    I am using One plus 7 pro.
    I am based in Germany and using Airtel sim from India for past 2.5 years. Sim is working till last week and now, there was no signal at all. When I reinsert the sim, it displays this error ( MM phone services: Sim 2 not allowed). I got an update recently and after that it seems to stop working.
    Could someone please help me solve this issue. Thanks a ton in advance! I have attached the screenshot error here below.

    Hi, check the gold contacts on the sim card and ensure they are clean. If that does not help, try the other sim slot.

    That's the electrical connections for the sim card.
