Why can't I receive my mobile phone text message after it is sent?

1. It is suggested to insert a new mobile phone into a mobile phone card to send a short message test. If it is ok after changing the mobile phone, it means that there is something wrong with the original mobile phone system. After checking whether the settings are ok, only important data, such as address book, can be exported and backed up.

2. If this happens after changing the mobile phone, it means that there is something wrong with the mobile phone card. Go directly to the business hall to find the staff to solve it. It is estimated that a new SIM card will be made.
