I had bought my acer m3 a few months ago which worked fine with my airtel 5G sim, but when i bought a new airtel 5G sim and tried to connect to the Acer m3, It is showing "No Service" for some reason and not able to connect internet to any device. Could you please give solution for this.

Thanks in advance
