After Samsung cover 5, the mobile phone, has been restored to factory settings, sending and receiving SMS has been delayed, and SMS is being sent. There is no SMS center in the settings, it is a telecom version. Dear Samsung users, hello:

According to your description, if there is a delay in sending and receiving text messages, I suggest you:

1. If you try to change other geographical locations, the signal strength may be weak.

2. Take out the SIM card and insert it again; Or try to change another SIM card.

3. Back up data (contacts, text messages, pictures, etc. ) and restore factory settings (Settings-User and Backup-Reset-Restore Factory Settings).

Please upgrade your mobile phone and try again.

If the problem still exists, it is suggested that you take the purchase invoice, maintenance card and mobile phone to the local Samsung service center for professional engineers to help you test. Please click the following link to find out the specific location of Samsung Service Center:.
