Thank you very much for the clarification. I have never been very into technology stuff and apparently just take things like that for granted.
It's amazing how much I've learned about the strange new world of hardware, software, operating systems, industries built around data collection, and more, just from trying to research, buy and use a new phone. I guess I've been living with my head in the sand for quite a long time now.
No, I am using the at&t go phone service. They are the only carrier that seems to get any signal in my out-of-the-way backwoods area.

I kind of hate the company(not that I have particular reason to believe their competitors are any better). I've had MANY strange service and account issues, some of which have never been completely resolved. Used to have to drive 125 miles round trip just to pay my bill. My Auto Pay used to malfunction every month. I'd lose service, try to pay over the phone, card would decline(any card I, my friends or family had), then I would drive all the way to the kiosk in the nearest big(ish) city and the same cards would work every single time. Months of this. On top of this, various landlines and non-at&t incoming callers would often receive an "account not in service" error message when trying to contact me. I could always call them though. It just so happened that my doctor, dentist and lawyer's office were all landlines that couldn't connect. Over a year of this. Mostly better now, no thanks to the million hours of talking to at&t employees, but every once and a while somebody still won't be able to get through to my account. I spent a ton of money and time battling these problems.
Rant over.
