What is ‘Not Registered on Network’ Error?

Simply put, the ‘Not registered on network’ error occurs when your device isn’t able to connect to a cellular network. In this case, you won’t be able to use your phone for communication or access any online services. 

A broken or faulty SIM card is one of the most common causes of the ‘Not Registered on Network’ error. If the SIM card is not properly inserted, is damaged, or is not activated by the network, the device will not be able to connect. 

However, there are other reasons behind this error, these are:

1. Poor network coverage.
2. Cached data.
3. System glitches.
4. Network setting issues.

Whatever the cause is, the below fixes will be able to resolve and get rid of the “not registered on network” error. Let’s start by re-inserting the SIM card.
