Recently i bought a Redmi Note 13 5G in Germany and while other functions are working fine, I am not able to make calls or receive calls on my Lebara SIM. Whoever is trying to call me is receiving a message that the user is not reachable and within few seconds I receive a SMS about the missed call alert. The SIM seems to be working fine as I tried it from another phone and it is working without any issues. Internet works fine using the same SIM data connection. Swapping the SIM slot also does not help. Any suggestions?
