Please do SIMMI test to check if there is hardware issue or not 👇
Open calculator>press .12345+= >single test>sim signal test.
if test pass than there is no issue with your hardware but if test fails than there is definately a problem with hardware,& you have to take your device to nearest service centre as early as possible and please don't forget to backup your important data before you submit your device to nearest service centre.
Thanks!

Hi, Please try the troubleshooting tips below:
1. Take out the sim cards> Insert the empty sim port to the end>Re-insert the sim port with sim card
2. Please try reset Network: Settings>System>Reset options>Reset Wi-Fi, mobile & Bluetooth
3. 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.
