*Our Prepaid AlarmSIM Cards work on practically any unlocked Wireless GSM Home Security Alarm System that operates on any of these GSM frequencies: 850/1900/1700/2100 MHz (850/1900/1700/2100 MHz will work in the US on our platform) and on the 2G/3G/4G LTE spectrum (where service is available). This service is not intended for use in medical or 'life saving' devices. This service is great for use in MMS "Trail Cams" that require MMS. Will also work in "Trail Cams" that have the option of using data to send images via e-mail.
