This should put a little downward pricing pressure on Walmart's value cellular plan, Straight Talk. 3GB at high speed per month, then throttles down. Unlimited text/talk. The bill, with taxes, is under $50/month and you can buy 3/6/12 month packages for discounts. The catch is if you want the latest iPhone 5S w/ 64gb, you have to purchase it from Apple sans plan.
My beef is the high-end phones are often left out of these plans.
