A lot of U.S users who purchased AT&T iPhone 6s or iPhone 6s Plus wished to also get the announced AT&T WiFi calling 2015 option. However this feature hasn’t been released yet. It is being delayed and millions of subscribers are now upset.
While AT&T WiFi calling iPhone 6s option is not working because the mobile operator is awaiting for the FCC to approve this feature, users who are subscribed to Sprint or T-Mobile can enjoy the wonderful calling iOS 9 option. You might even want to unlock AT&T iPhone 6s or 6s Plus right away and become SIM free to use the feature with a different network provider while waiting for your original carrier to get the approval.
AT&T WiFi calling release date was expected right after the ‘s’ lineup launch. The company was testing this option together with Apple in the end of the summer. This made a lot of users believe that they would get iOS 9 WiFi calling right after this firmware update. Apple indeed upgraded its mobile operating system and has already launched two versions: iOS 9 and minor iOS 9.0.1 update. At the same time, AT&T is still holding back on releasing the WiFi calling on its network.
AT&T hoped to release its WiFi calling service without offering TTY support for hard-of-hearing and deaf people. It has to get the FCC approval to make this happen. It is curious that both Sprint and T-Mobile that launched iOS 9 WiFi calling feature support do not offer TTY support as well.
Originally AT&T WiFi calling launch was planned on September 25th or 26th. The company is not going to offer the service unless it gets the approval. Are you going to wait for the option to be launched or do you plan to factory unlock iPhone from AT&T in order to use the option on a different network?
