Sim card issues on a Samsung Galaxy phone
Most issues with your SIM card will need to be resolved by your carrier, but before you contact them, there are a couple things you can try to resolve any issues.
Remove the SIM card and inspect it for damage or corrosion. Reinsert the SIM card, making sure it is properly installed in the tray. If you have another phone that works with the same carrier, try using the SIM card with that phone.
If you have another active line with your carrier you can try that SIM card with your phone.
If your SIM card continues to have issues, you will need to get a replacement from your carrier.
