From the moment the Galaxy S II and HTC Amaze 4G hit store shelves there was a lot of unanswered questions about Wi-Fi calling. Was it available or not available? Was it locked on the phone requiring an update to unlock? Was Wi-Fi calling no longer coming pre-installed on Android devices? As it turns out, the capability is there but the feature isn’t. The good news is we’ve got a solid answer on when exactly Wi-Fi calling will be ready for both of these premiere T-Mobile devices: November 13th.
We’re not 100% sure as to reason why Wi-Fi calling wasn’t enabled from the start but we can say with a measure of certainty that a specialized SIM card is required to ensure Wi-Fi calling works post November 13th. We should preface this and say that in order for this feature to work, you’ll likely have already used the SIM card that came with your Galaxy S II or Amaze 4G. If you pre-ordered or purchased in store you need to ensure that your phone has the “GBA SIM card” which came with the device at the time of ordering. If not, I’m sure a quick trip to a T-Mobile retail location can rectify the problem. You don’t have to rush however as anytime between now and November 12th would be good.
Assuming your phone is ready with the “GBA SIM card,” come November 13th you’ll be good-to-go with Wi-Fi calling on both the Galaxy S II and the HTC Amaze 4G. So there you have it, while it’s been a little bit of a mystery regarding Wi-Fi calling, we have our answer and we do like answers.
