Did you check if your account status is active? To avoid browser cache confusing, please login My account using Incognito mode to confirm account status
If it shows On Hold (Suspended) , then it is a payment issue. Click "Pay Now and Resume Services" to make a manual payment
If it shows active,
- first try to reboot the phone
- If that does not work, change the Preferred network type or network mode to 3G only or WCDMA only and see if it works
- Try to click Reset All Networks and see if it helps
- and do you have another phone to test the PM sim ? just to make sure it is not a device problem. Also, that can force a sim card re-provision and it could resolve the problem
- Also, try the phone in another area if possible, it could be just a local network outage
