Phone itself.  Under settings.  Carrier.

SIM cards are very robust so normally nothing could go wrong with them.

Take out the SIM and inspect for any scratches to the copper contacts and any physical damages.
Also check the SIM tray to see if it is bent or damaged. If it is, they are cheap to buy from Amazon.

If none then use some rubbing alcohol and clean the copper contacts with a micro fibre cloth.

You might want to try the old SIM card in another working phone. To see if similar issue.  It will help determine whether hardware/phone issue versus the actual SIM card.

What problems are you having with the old SIM card?  Sim cards rarely become defective.  Maybe there are other issues that we can help with.

You cannot ADD new SIM car, you can only replace existing SIM with a new SIM. And yes, it will work right away.

Go to Profile where you can do this:

- Change phone number

- Change SIM number

- Transfer Phone Number
