DMP released its second 3G/4G cellular communication option to address the impending 2G technology sunset. The DMP XT Series now supports HSPA+ 4G-capable digital cellular communicators from AT&T and T-Mobile. The 263H 4G cell communicator works on 4G, 3G or even 2G, depending on which network is available in a particular area. It also uses the existing 263G SIM car with no additional activation fees. The 263H complements the 263C and 463C CDMA cell communicators for Verizon that DMP introduced earlier this year.
