How to make fake short messages

What mobile phone model are you using?

What kind of software is there now?

You can download it if your mobile phone supports it.

I used NOKIA76 10, so I sent a flash message, which I sent to the other party. She could only read it once and it was gone. There are also SMS scammers, just like you said, software that specializes in making and demonstrating SMS, and can also encrypt SMS.

I hope it helps you!
