US Cellular’s Galaxy S5 (model SM-S902L or R960 ) is often carrier-locked. Even with a valid SIM, the phone will reject non-US Cellular SIMs. If you’re trying to use a different carrier’s SIM, the “Invalid SIM Card” message is expected. You would need to request an unlock from US Cellular (must meet their unlock policy: paid off, account in good standing, etc.).

: A simple reboot can refresh the connection between the phone and the SIM card. Reseat and Clean : Power off the phone and remove the back cover and battery. Remove the Micro SIM card from its slot.

A simple reboot can clear minor software glitches that prevent the SIM from being recognized.

Sometimes, a simple reboot can resolve the issue. Turn off your Galaxy S5, wait for 30 seconds, and then turn it back on.
