Straight Talk might give you a "Not registered on network" error for several reasons. It could be because your device entered airplane mode and failed to connect to the Straight Talk cellular tower. It could also be because your Straight Talk SIM card is not inserted correctly.
This article will guide you on fixing this error and returning to the Straight Talk network in no time. Your issue with the Straight Talk "Not registered on a network" error will be gone.
Why are You Getting "Not Registered on Network" on Straight Talk?
If you notice a "Not registered on network" error on Straight Talk, it may be because the software is not updated and your phone is running an earlier version of the software.
Also, when your phone is locked to another carrier, it may display such an error. Unlocking your phone might help.
