The Model 4598 is an unlocked 3G+ mobile broadband modem that works with AT&T in the US and most service providers around the world. The 4598 supports data rates of up to 7.2 Mbps on downloads and 5.76 Mbps for uploads using a wide range of cellular data communications standards including: HSDPA, HSUPA, UMTS, EDGE. The modem is activated by plugging in the SIM card from a service provider. Unlike other modems, the Model 4598 is not locked to a specific service provider and can use a data SIM from many GSM service providers or a voice/data service SIM from a smartphone. A change to the service provider is accomplished by simply sliding out one provider's SIM and replacing it with another provider's SIM. GSM frequencies can vary from country to country. The Model 4598 uses any of three high-speed frequencies, which provides broad compatibility with high-speed GSM-based mobile data services in countries around the world. The 4598 supports voice calls using a PC with a microphone and speakers or headphones. This allows the use of the SIM from a smartphone to by used by the modem while retaining voice communications. A micro-SD slot on the modem accepts a memory card for up to 8 GB of memory. A simple slide-in of a micro-SD memory card allows the modem to double as a portable storage device to maximize the flexibility of available USB ports.
