I need to monitor a remote site access using a GSM alarm.

We have been using the G Smart units from Jaycar which are good but seem to die after a couple of months?? I have a couple of sites that use them and both have stopped working for some reason.

Done all the usual checks, money on prepay, taken the SIM out and  made sure it works ok from a standard phone and put in a different SIM into the module. Since we have had the exact same fault on three g smarts its time to find something else.

Can anyone suggest a suitable device??
