Suddenly a number 10690079 sent a text message saying that I seemed to feel that I had clicked the master key to allow me to send text messages, or some software.

Hello, have you downloaded any games or software? If it is background automatic message sending, I suggest you download antivirus software to scan it.

If it can't be scanned, I suggest you rule it out one by one. Or directly restore the factory settings,

Wifi master key will be automatically sent to 10690079, but it was checked when it was installed. If anti-virus software is used to prohibit sending short messages, it will not.

Honey, my answer can help you. Please adopt it.
