Before I got the gov't. freebie phone for poor folks, I had a TracPhone. Phone itself was about $30., and I bought a card for minutes; $20 for 3 months service. No contract, no minimums .
Phone was pretty wimpy crap; only good for basic calling, no internet. etc. and it was really good at not getting signal inside of buildings, but it was fine for emergencies.
The freebie phone I have now works better, has a better camera, gps, texting, and internet, if I want, I think I get something like 5 MB of data before I'd have to buy note, but I don't use it much for that. Only requirement is I have to make a minimum of 1 call per month.
But to qualify, you have to be a recipient of either Medi-Cal or food stamps. That part got me the free phone, but I hate being in that position.
