This thread has me looking into used tablets with SIM card slots. As I travel I don't want to chew through my real data but I can buy SIM cards for a buck and put them on month to month carriers with no paper trail. I could sign on as Peter Norton or Bill Gates, pay for the month with a prepaid Visa card, and sign in with a fake address so I would be untraceable. I have done this in the past when I wanted to have some fun with scammers, texting and emailing back and forth as if I was a viable target for them. In fact I have a drop phone right now that I have not yet activated.

You can buy Simple Cellular and Mint Mobile cards for a buck or two at Best Buy and Target. $15 a month for service.
