Any recommendations for a dialler to nail onto our Scantronic wired panel? Our 2G service has just been switched off so the dialler no longer works. Ideally, I'd just like to send a text message to 4 numbers sequentially with the option for first number answer to cancel further calls.
 
can't remember the make of the unit I ftted afew years ago, but it was triggered from the output relay of an alarm baord, and was a self contained unit.
 
I presume it is the GSM Communicator – GJD710?

If so, it seems that it is 2g, and you "may have to order the 3 g version" (Yes, I know 3g will also be obsolete soon)

Have a look at page 3 Click here

Hopefully they will have updated it.

Thanks for the info, yes I need to get to 4G to get some realistic life out of it.
