A Subscriber Identity Module (SIM) card identifies a device to the mobile network using a unique 64 bit cellular user ID known as the International Mobile Subscriber Identity (IMSI). An IMSI identifies Global System for Mobile Communications (GSM) and Universal Mobile Telecommunications System (UMTS) subscribers to their mobile network. The M2M Hybrid SIM gives global data flat rate service using only a single IMSI while competitor’s offerings use multiple SIMS or dual IMSI SIM cards requiring two or more mobile subscriptions.
In order to extend the value of your flat rate data allotment, the Hybrid SIM uses a unique patented technology to compress position and other data prior to transmission over the visited mobile network. This compression feature, embedded within a global data sim card that works as a local card everywhere it goes, sends data as quickly and economically as possible no matter which network service is used, whether it’s GPRS, UMTS, CDMA, LTE, SMS, or any other supported bearer service.
