Top Ways to Fix SIM Not Supported Error on iPhone

Let us begin the troubleshooting to fix SIM Card Not Supporting Issue on iPhone

1. Insert the SIM card Properly

When the SIM card is not placed properly into the space in the SIM tray, it cannot establish the network with the carrier.  To fix that, take out the SIM tray off the iPhone. Remove the SIM card and correctly put it back on the SIM tray. If possible, clean the SIM card with a soft clean cloth before inserting it back. This troubleshooting is for those iPhone models that support physical SIM. Also, restart the iPhone.
