Why does my mobile phone send a text message to a British number for no reason?

The mobile phone sends SMS automatically, which may be related to the software used. Suggestions:

1. If SMS is sent automatically after opening a software, it is recommended to check whether there are calibration settings in the software settings, such as calibrating traffic.

2. Try to restart the phone.

3. put the SIM card of the mobile phone in other machines, observe whether the same problem will occur, and rule out whether it is related to the binding service of the SIM card.

4. If SMS is sent automatically only in this mobile phone, please back up the data (contacts, information, pictures, etc.) in the mobile phone and try to restore the machine to factory settings.

if the problem still exists, please bring the purchase invoice, repair card and machine to Samsung service center for inspection and handling.
