Red Pocket is offering a new 360 day plan in their ebay store-- unlimited voice (including international to 70 countries), unlimited text, and 5GB for $240/year. ($20/month). This plan is available on your choice of AT&T or Sprint networks, but not on Verizon or T-Mobile.
Not a great fit if you're using CellNuvo to pay your Red Pocket bill, but a very good price. If Sprint fits your needs best with this plan, they will apparently send a Sprint SIM at no cost, too.
