Network problem

[Deborah]

Hello @Hassan,
have you tried turning your device off and on again? If you still find the criticality, enter the settings of your phone and move the network from 4G to 2G (3G if you have an Iphone), restart the phone and bring the network back to 4G.
If unsuccessful, check the functionality of the SIM in another device. Let me know, I remain available. Have a good evening.
