My hookup at Walmart understood what I wanted--a phone to call my girl, I said, without anyone knowing, and one I didn't have to give any personal information away to activate. He ran down the different options. I asked him "What would you get?"
"Straight Talk"--3 GB high speed data, unlimited talk and text, works on your unlocked phone or buy a phone and activate. Can be activated without talking to anyone. Absolutely anonymous. Better yet, it runs on AT&T's network for only $45/month--far less than AT&T charges for the same service to its paying AT&T customers. I was able to activate my hobby phone, access the internet, and do all my email using the phone and Straight Talk. Minutes and data don't roll over so just buy a new refill card every month and you are golden.
Hope this helps those of you trying to figure out what is the best service for you.
