What's wrong with Apple's 5s not receiving SMS?

1. Check whether the mailbox is full first. If it is full, please delete some information;

2. If it is still not received after deletion, you can change the machine or card to see if it is a hardware factor;

You can try to test whether it can be received in other places and see if it is the reason for the weak local signal.

1. Confirm that the signal is normal and close the flight mode.

2. Check whether the SIM card status is normal.

3. Check whether the send key is bright and clickable.
