SMS commands from Phone to SW-RV50

Hello you guys.

Can anybody help commands sent from my mobile phone to my RV50’s modems/routers.

Especially I need a RESTART command, so I will be able to sent a sms to my routers to perform a restart.

If you have any other usable sms commands I will be happy if you share it with me.

*I have search the forum for topics regarding this - but all I had found was regarding sms FROM the router to phone.
