Can I send regular short messages after Red Rice note is turned off?

No, when you have to realize it, I think of a feasible method. Timed SMS+time switch machine

First, set up automatic SMS sending, and then turn on the security center-power-time switch.

It is set to turn on the power two minutes before sending the message, and then turn off the power two minutes after sending the message, so as to reserve time for system startup and message sending, or to reserve more time.

Although it is very troublesome, it can still be realized, because what this function lacks is that the information does not have the function of automatic on/off, but the alarm clock can be turned on automatically, because with this function, the automatic on/off of information is a bit idle.
