My SSV ute and now my current car have been protected by a car alarm which can respond to SMS commands like arm/disarm and send me messages if something sets it off. Perfect for me with my disabilities.

However, as I found out to my annoyance recently, the alarm has only 2G capabilities, so my Telstra SIM has stopped working. I can change to Optus or Vodaphone which could take me out towards the end of 2017 (Vodaphone) but in the meantime want to start looking for an alarm which works on 3G and hopefully even 4G.

I've Googled but can't find any. Given my lack of speech it's not easy to ring places so when I do (through the NRS) or email them I'd like to be more specific and talk about particular models if I can.

Does anybody know of a car alarm with 2 way SMS communication using the 4G, or at least 3G, network please?

Thanks,
Gary
