Replace the SIM From Your Carrier
The last resort for this issue would be replacing your SIM. You can easily get a new SIM with your current number without worrying about losing contacts.

In that case, you have to visit the official or authorized mobile repair centre. Nowadays, most of your mobile support E-SIM. Since E-SIM is implanted inside the mobile, it has few chances of getting damaged or lost. So, you should also consider getting an E-SIM if your carrier supports it.
