My ex and I got cell phones in the early 1990s. Expensive as hell, but I felt a lot better with her having one. Came in really handy when she broke down in heavy traffic on the Washington beltway.
I gave it up after we broke up (she had the plan). I later got one through my employer. REALLY good deal -- huge group purchase so the plan was really reasonable. Something like $6.99 a month for the basic fee, but the minutes were steep, especially the roaming minutes. That's the number that I still have.
I didn't get my first Smartphone until... 2014 or so, I think. It was a Motorola droid. What a piece of crap. When I finally got out of the plan with that one I got my first Samsung Galaxy and haven't looked back.
I was with Verizon all of those years. Their plans were... not good. Expensive and I was limited on data and minutes, but their coverage was really good.
Data was the big problem, as I was commuting a lot. Minutes not a problem as I didn't make that many calls, or get that many, either.
When I started working at AT&T, I of course switched my cell service over to them. Half off the plan that I'm on, with unlimited minutes, data, and text. I pay $47 a month. Can't beat that with a stick.
I'm not as crazy about AT&T's coverage, though. There are areas where it's spotty and when I walk into my house? My signal goes away. Down to zero bars. I walk out my front door and all my bars are back. Fortunately the phone has VOIP calling mode so it links right into my home network and I'm fine.
