Hi rgmobile222
Thank you for your asking. Kindly try some stay-at-home troubleshooting tips below:
1. Change the SIM card. Does the device work with other SIM card?
2. Can your SIM card work with other device? Please try to re-insert the SIM card.
3. Does the issue appear right after any system/apps' download or update? Please try to enter "Safe Mode". If the function works well in Safe Mode yet the issue remains out of Safe Mode, please check on any disturbance from the installed 3rd party apps.
