my network connection to fizz have not been worked since 2 days ago. I talked to support service and it does not fix. my plan is active. I changed the device and my sim card does not work in another device as well. I reset the network and set the configuration again, restart some times, nothing happened. it shows a message "sign in to network" and it does not show any thing after click on the message!!!
I really do not know how can I fix it!😞
