So, I'm setting up an alarm system in my home and its dial-out function will probably be using a phone SIM card. I'm trying to make this as inexpensive as I can.
The two choices I've had suggested are:
1: Having it as a "second phone" on my regular mobile account. I don't have a mobile, so that's out.
2: Having it use a prepaid SIM card with rollover, which is apparently pretty rare.
Any bright suggestions will be appreciated!
