I’m with @YoBob… more or less. I have a Net10 account, also with a decent Samsung slide-out full keypad on a “dumb” phone. (I like that keypad for infrequent texts, and for adding user information to my directory; the iPhone features look nice, but pricey.)
I don’t even pay as much as he does. A few years ago I had a problem that took Customer Service several days to resolve, and every day when I’d call I’d go through a whole directory of well-meaning but incapable CS people. One of them finally told me, “Look, we’ve been messing with this for days and days, and you’ve been more than patient, so I’m going to fix one thing for you for certain, right now.” He gave me some codes to punch into the phone, had me wait for confirmation, punched in more codes, then had me look at the display.
I’m now “paid up” with continuous service (although I still have only 500-odd paid-up minutes) through sometime in 2038. That is, my minutes won’t expire until then. (And at the rate I use the phone, I may not have to renew the minutes until around 2020.)
