Isis is expected to begin its pilot phase on Aug. 20 in Austin, Texas and Salt Lake City, Utah, according rumors reported by TmoNews.com. The mobile-wallet venture by AT&T, T-Mobile and Verizon was slated for a summer trial launch but Isis never provided a specific date.
Currently, devices that support the Isis Mobile Wallet includes the HTC Amaze 4G, Samsung Galaxy S II and Samsung Galaxy S Blaze 4G. Other devices may join that list as the launch date approaches. Chase, American Express, Capital One and Barclaycard have already partnered with Isis.
Earlier this month, Isis released a set of tutorial YouTube videos that offers more details on the user experience — possibly in preparation for an impending launch.
