GPRS alarm systems are fully monitored, meaning that any activation alerts are sent directly to an Alarm Receiving Centre (also known as ARC). If the ARC is notified of an activitation they will contact the registered key-holders and advise them of the activated alarm.
Running costs of M2M SIM Cards for GPRS Alarm Systems
GPRS systems require a M2M Security SIM card and this can be purchased as Pre-Paid M2M SIM for just £48 per year at.
M2M Security SIMs supply M2M SIM cards for use in GPRS alarm systems and GPRS devices. We supply Multi-Network SIMs that provide coverage across the FOUR UK GPRS networks. If a network goes down or a signal cannot be gained from one network, it will automatically switch to the next strongest mobile signal from any one of FOUR UK GPRS Networks; Vodafone, O2 , Everything Everywhere (previously Orange & T-Mobile) and 3, this means for you is that you should never lose signal.
