5. Replace SIM Card
Modern smartphones have reduced the size of their SIM card tray. This means that you have to downsize your standard-sized SIM card to micro or nano depending on the requirement. A downsized SIM removes the extra plastic region around the gold plates. It is possible that while manually cutting the SIM card you have somehow damaged the gold plates. This results in the SIM card being damaged and unusable. In this case, all that you can do is get a new SIM card and then get the same number ported to this new card.

If you see the same problem on the other device, then your SIM card has been damaged and it is time to get a new one. Also Read: Fix Gboard keeps crashing on Android
