Interesting news comes from AT&T as they enable international Wi-Fi calling with iOS 9.3 updated today. This means that all U.S. owners of an account with that mobile provider, can now freely call internationally over WiFi and scratch dose nagging int call expenses. This is a further upgrade over the domestic calls enabled on WiFi for AT&T customers that was rolled out earlier last year.
While negating international cost fees is the foremost aspect, it also helps with areas where cellular service is rather poor. While supported in many countries, the feature is currently restricted in China, Cuba, India, Iran, Israel, North Korea, Pakistan, Saudi Arabia, Sudan, Syria, Turkey, the United Arab Emirates and Vietnam. This comes as a no surprise, as all of these countries have specific political/economic aspects that aren’t up to telecom’s needs.
When the user is connected to WiFi, the system automatically re-routes their voice traffic to go over WiFi instead of the telecom provider. In order to use Wi-Fi calling on iPhone, you will need to enable this. Simply visit Settings > Phone > Wi-Fi Calling and toggle the “Wi-Fi Calling on This iPhone” switch to the on position. Users activating the service for the first time might have to navigate through an initial setup process. For the time being, the feature is limited to iPhone 6, iPhone Plus, iPhone 6s and iPhone 6s Plus models.
