The Verizon Droid Incredible 4G LTE by HTC (really? enough with these names) is getting an update today that brings both international roaming capability and Isis mobile payments. Verizon has unlocked several of its devices for international roaming lately, and now the Incredible 4G LTE is on the list. When the device is being used domestically, however, this update is supposed to improve LTE performance as well. Isis mobile wallet is the other big story here. Isis is the payment standard being pushed directly by the big carriers in the U.S. and competes directly with Google Wallet. We've seen indications recently that Isis is finally ready for an unveiling, so this update is coming just in time.
The hefty update -- about 155MB -- will be coming OTA (Over the Air) to all devices and is considered a "mandatory system update" by Verizon. Instructions indicate that the phone will reboot 5 times during the installation, so don't be alarmed if it takes a while to install. If your device hasn't prompted for the update yet, you can check for it in settings > software update > check now.
