Others can't get the short message I sent.

If the message sent by the mobile phone is not received by the other party, it is recommended that you refer to the following contents:

1. This phenomenon may be caused by the other party's mobile phone, so it is recommended that the other party check the relevant settings of the mobile phone.

2. All contacts send messages with this phenomenon. I suggest you check whether the network signal is stable, and try to restart your mobile phone and change your geographical location.

3. try to replace another SIM card.

4. standby-application-settings-application manager-all-open information-clear data attempt.

5. back up the data (contacts, text messages, pictures, etc.) and restore the factory settings (settings-reset/privacy-restore the factory settings).

if the problem still exists, it is recommended that you take the purchase invoice, repair card and mobile phone to the local Samsung after-sales service center, and a professional engineer will help you to test it.
