Seeing the "No SIM Available" message on your iPhone or Android can be frustrating, especially if you rely on your mobile connection for calls, messages, and data. But what does this message mean, and how can you fix it?
This guide will walk you through the causes of the issue and the best troubleshooting steps to get your phone connected again.
What Does "No SIM Available" Mean?
The "No SIM Available" error means that your phone cannot detect a valid SIM or eSIM profile. This could happen for several reasons:
Physical SIM cards: The card may not be inserted correctly, is damaged, or the SIM slot is faulty.
eSIM users: Your phone might not be recognizing your eSIM due to a software glitch, incorrect settings, or a network issue.
Device-related problems: Your phone's settings, carrier information, or network mode may need adjusting.
If you use Firsty eSIM, your phone should never have this issue due to a missing physical SIM, but if you do see this error, follow the troubleshooting steps below.
