I would like to be able to select on demand SIM1 or SIM2, but not as a fallback automatically. Rather I would like to switch via CLI or even better via SMS to CLI. One issue I noticed is that when SIM2 is selected the option for “Send received SMS messages to the command interpreter” is not available? Why would SIM1 allow “Send received SMS messages to the command interpreter” but not SIM2? Tried different configurations with dual SIM wizard but getting what I really need, the ability to switch on demand from 1 SIM to another… ---

Hi The router can only receive or send sms messages only on the sim that is currently live. from the CLI the configuration of SMS(2) is carried out under MODEMCC 0 SMS\_\*\_2 commands. If you have setup dual sim where it uses 2 PPP instances you could force the router to bring up the other PPP instances PPP 2 ACT\_RQ this would get the router to start PPP 2 you might have to drop ppp 1 PPP 1 DEACT\_RQ these would have to be sent at the same time if you use the sms\_cmd\_sep command “;” then ppp 1 deact\_rq ; ppp 2 act\_rq hope that helps ---
