How to make mobile phones unable to send short messages?

1. Save it in the draft box after writing, and then move it to the outbox to try.

2. If you want to know someone's name, you can go to an inactive number and save it in that person's name, and send a short message to that number. When you finish sending the short message, it will show that it has been sent to that person.

3. If 2 is not good enough, you can send a number that is easily confused with someone to this person's name, such as 13823 12xxxxx, and you can get a number 1382 132xxxxx, and the display has been sent to this person. But both 2 and 3 are easy to expose, depending on your actual situation.

4.4. Some 4.4.nokia models send text messages when the sim card is out of money. Even if they are not sent, they will be displayed in the sent one. I don't know if your 6070 is like this. If it is, it will be easy.
