Good morning everyone,

as I learned yesterday that there is no way to use two SIM cards simultaneously and that there's no way to trigger a script by SMS I have a couple of questions regarding best practices.
As I have two SIM cards, SIM1 with a data only plan und SIM2 with a "normal" mobile plan I'd like to use SIM2 in "standby" mode and switch to SIM2 for a mobile data connection.

  • Is there a way to switch to a certain SIM card in a script(e.g. SIM2 regadless which SIM is active at the moment to use a defined SIM card)? To toggle between the cards was the only solution I found in the manual.
  • Is it possible to trigger multiple actions by SMS command (e.g. send SMS, force SIM change, WiFi on)? Perhaps use all the commands in one SMS?
  • Is it possible to trigger multiple actions by using a digital input (e.g. Wifi off, force SIM change, send status via SMS)?
  • Is it possible to trigger a script via digital input?
  • If not via SMS what is the best way to trigger a script? Switch do data SIM, open a VPN tunnel, use SSH to execute script?

I appreciate any hints to point me in the right direction.

Best regards,

Thanks for your answer.

But this covers only that it is possible in general and unfortunately didn't help me much.

Please telle me:

  • how to trigger a script from Digital Input. It's not covered in WebUI or in the manual.
  • where do I find information which simcard is active. It's not to find in sim_switch or simcard.
Thanks for your help!

You need to have a good understanding of busybox, I do not have time to write the code for you, sorry.
