We first got wind of ISIS, a mobile payment service that's a joint venture between AT&T, T-Mobile and Verizon, way back in late 2010. The first trials of the service were originally supposed to kick off in the early to middle portion of 2012, but then the trials got pushed back and were expected to get underway before the end of summer, likely sometime this month. Now it looks like it'll be even longer before the ISIS tests get underway. A company executive has told Reuters that ISIS's launch in its first two markets, Salt Lake City and Austin, has been delayed. Jaymee Johnson, head of marketing at ISIS, wouldn't say why the service is being delayed, saying only that the company is currently "wrapping things up and finishing that final punch list of items." Johnson added that ISIS now plans to announce the new timing of its launch in October.

As I mentioned before, the first ISIS trials have been a long time coming, so it's kind of a bummer to learn that we won't finally get to see the first trials of the service get underway this month. Since ISIS is a new mobile payment service that has the backing of three of the four major U.S. carriers, many folks are interested to see it in action and compare it to Google Wallet, which is currently only available on a handful of (mostly Sprint) devices. Of course, ISIS will only be available in Salt Lake City and Austin initially, but the company has said that it intends to extend to other cities in 2013. Now we just need the initial trials to get going. We'll let you know more about when that'll be happening once ISIS announces the details, which hopefully won't get delayed past next month.
