Airtel : SIM 1 not allowed

[Ani24T]

I am getting "SIM 1 not allowed" error on my Samsung Galaxy Note 8. My network operator is Airtel. I have restarted my phone several times and also tried selecting network manually with no luck. Any idea on how to fix this?

Most of the Airtel users facing the same issue...I'm also one of them ...there is nothing to worry...just change the sim card with same mobile number ..it will work ...Airtel office only charge for sim card ie 25rs...sim will activate in jst 2 to 3 hrs

I've Samsung A50, got an error  "sim one not allowed" but sim two working fine. I've reset my phone, change firmware country Pakistan to India, tried with other sim card, both IMEI are approved on service provider end, replaced its transmitter IC but error remain same as before, applied some more soft tricks to get rid of it but failed. If anyone get solution then pls reply me. 

Thank you
