Once upon a time, T-Mobile launched UMA services for their WiFi enabled smartphones.  This allowed customers to make calls via WiFi and it was unlimited.  Then later on T-Mobile enforced that the minutes would deduct from your plan on WiFi or cell towers.  Now the company is offering its original unlimited WiFi calling once again for those who have UMA enabled smartphones!

T-Mobile is 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.

So now feel free to enjoy free WiFi calls on the T-Mobile network.  BlackBerry devices that are supported include the BlackBerry Bold 9780/9700, Curve 3G 9300, and Curve 8520.
