What about e66 automatic SMS?

It is not clear whether LZ will let the background send text messages automatically or set text messages manually.

1. If it is set manually.

If it is not in the mobile phone settings, it is generally impossible to set it. If you don't need it, you can refer to the instruction manual (if you bring it) or ask the boss when you bought it to teach you.

2. If it is a background SMS, it is recommended to stop using the mobile phone immediately, call the operator to inquire and cancel the additional service.

Because the shanzhai are all solidified information, and they are all non-intelligent machines, which can not be completed by brushing the system. You keep using it, and he keeps sending it until you run out of money, and the operator can't stop him from sending text messages automatically.
