What's the matter that the new mobile phone can't receive text messages?

The number of SMS center is wrong, and the local signal is unstable.

Some models involve customized versions and the differences between parallel imports and Hong Kong banks. The SMS center numbers of these models are generally not mainland SMS center numbers, and licensed mobile phones will become factory settings after refreshing or restoring their factory settings, resulting in mismatched SMS center numbers. The user's own setting error may also lead to incorrect SMS center number, so the main reason why the mobile phone can't send and receive SMS normally is mostly related to the wrong setting of SMS center number.

The signal is unstable, the network is temporarily missing, or influenced by other aspects (magnetic fields, tunnels, or other network blind areas), and some closed situations (elevators, subways, underground garages, toilets) will also appear, which will also lead to the temporary unavailability or delay of short messages.
