after the year if you want to move to another cell carrier?

I have a $25 Android with Tracfone that works for me.

ATT were total jerks about it, but they did it, and T Mobile put their own chip in. My phone is going on three years. Earlier ones you were stuck w the carrier.

I have an auto refill plan with Tracfone that costs me about $6 a month for 60 min, 60 texts and 60 MB data. That might not be much except that I have quite an accumulation of all three from my previous triple minutes phone because I'm a light user. I use WiFi a lot. If I ever run low I can buy a more expensive refill.

When I hear about $50+ a month plans with Verizon or whoever, I can only roll my eyes.

I've had two Android phones before this new iPhone. They were fine--first a flip phone and then a moto e smartphone. They were fine but the latter ran out of storage space all the time so I needed an upgrade.
