If you own a CDMA version of the iPhone, you can update your roaming capabilities by dialing a number from your phone directly, which can increase your battery life while roaming, allow your iPhone to connect to additional roaming networks and decrease the amount of blocked and dropped calls. Updating your roaming capabilities is not required if you own a Verizon LTE model of the iPhone 5 or an iPhone on a GSM network like T-Mobile or AT&T.
