We had thought that T-Mobile was going to officially bring free and unlimited Wi-Fi calls back on May 11th but the announcement never came. Fortunately, today, Kineto Wireless and T-Mobile both confirmed that Wi-Fi calls with phones that support UMA are now free.
In a message passed along to GigaOm today, T-Mobile stated that it’s:
…excited to expand our Wi-Fi Calling feature, a unique and valuable service T-Mobile has been offering customers for over three years. Starting today, T-Mobile customers can add Free Wi-Fi Calling to their rate plan – at no additional charge – to place calls over Wi-Fi without deducting from their allotment of minutes. This new feature is available at T-Mobile retail stores to all customers on Even More and Even More Plus Postpaid rate plans who have Wi-Fi Calling capable handsets.
Before reverting back to this, T-Mobile had been counting minutes spent over Wi-Fi toward overall minutes. However, now that this is back in action, any calls you place over a Wi-Fi network using this feature will be free.
