It will have global roaming VERY SOON LIKE AT&T. Verizon with 4G LTE has switched to GSMA UICC SIM-based technology which is totally awesome and I believe in Q1 2011 once VZW updates it's back-end systems and switches customers from the 3G Vodafone/NL/faux-SIMs to real Verizon SIM cards being installed in customer devices like all the 4G LTE devices those UICC SIM card #'s and serial #'s attached to your account will be enabled to allow global HSPA, HSPA+ roaming overseas all billed back to your US VZW account like it currently does with international services (and a headache with dual CDMA and GSM technologies). With LTE it makes it 10x easier as VZW domestically is using the SAME technology as globally.
I don't know if VZW has opened a global-roaming APN yet for roaming but it will soon.
All the customer has to do in 2011 is to call customer service that they want GSM UMTS, HSPA, HSPA+, EDGE, GPRS global roaming and the customer's 4g lte SIM card profile will be updated in VZW's system to allow global roaming. All that is needed on the customers computer is a software and driver update which will enable the hardware features of the UML290 which supports back-ward capability of HSPA, HSPA+ (21Mbps down, 5.76Mbps up and MIMO so double those #'s, what AT&T and T-Mobile currently use in the US) and EDGE, GPRS on 850/900/1800/1900/2100MHz support globally. ❤️ GSM technology and GO VERIZON and the amount of $$$ you put into the network!
