Question

Where do I get a SIM card for my GSM Alarm System? What size of SIM card do I need?

Answer

The most common options are AT&T and T-Mobile. T-Mobile has a prepaid $100, 1000 minute plan that lasts for one year (about $8.30 a month).

In Canada, the larger carriers that are compatible are Rogers and Fido.

Only GSM carriers can provide a compatible SIM. Verizon Wireless and Sprint cannot be used. If your personal cell phone is on Verizon Wireless or Sprint, you can remain a customer and still purchase a prepaid SIM from AT&T or T-Mobile.

There is also no issue with the system calling a Verizon or Spring phone when using a AT&T or T-Mobile SIM.

The system uses a standard size SIM card, not a micro or nano size.
