Recently, the Motorola DROID RAZR and RAZR MAXX were updated to Android 4 ICS, but the update also unlocked the Qualcomm MDM6600 radio chip to allow the phone to work on other networks while outside of the US, including GSM/EDGE (850/900/1800/1900 MHz) and UMTS/HSPA+ (850/900/1900/2100 MHz) networks.
We've received word from Verizon that the brand new HTC DROID Incredible 4G LTE will also be granted Global Roaming via a future software update. It is unclear at this point how far off that update may be, but it is a good sign that the Verizon is listening to its customers that want access to 4G LTE while in the US, but still have the flexibility to use their smartphone for voice and data while in other countries. Verizon has not commented on which Global Roaming bands the HTC DROID Incredible 4G LTE will eventually support, but since the device uses the Qualcomm Snapdragon S4 MSM8960 SoC, we can speculate it will be the GSM/EDGE (850/900/1800/1900 MHz) and UMTS/HSPA+ (850/900/1900/2100 MHz) networks. Keep in mind, the older HTC DROID Incredible 2 that came out last year was limed to only 900/2100 MHz bands on UMTS/HSPA networks.
