As initially marketed by Verizon, when first launched, the Droid 4 was not capable of roaming in countries with non-CDMA wireless networks. However, after installing the update from Android 2.3 to Android 4.0, global roaming is automatically enabled on the handsets, allowing the Droid 4 to use GSM bands and provide HSPA data connections outside the US. However, LTE speeds are only available on Verizon's CDMA network. Unlike previous versions of the phone, the Droid 4 does not have a hot-swappable battery.
