Try inserting the SIM into some other mobile device and try making a call with it. If everything works fine, then there must be an issue with your mobile device and not with the SIM. 

Method 7: Restart Your Device

Sometimes, the solution can be the most basic practice. This is why whenever you face any error with any device you use more frequently, it is advised to try fixing it with the basic solutions rather than contacting the professionals right away.
