For me the $100/year T-mobile plan is almost perfect. I have a smartphone and since I’m near wifi 90% of the time I get “free” texting. I rarely use the phone so .10 a minute is fine for voice calls and texts when im not on wifi. T-mobile changes prepaid options all the time, but this one has been on for years. I can switch on the fly to a pay by the day plan and get all the calls or texts plus 2g internet for $2 or upgrade the internet to 4g/3g(200megs then 2g after that) for $3. I’ve done that a few times over the months when I needed to and its easy to swith back and forth right over my phone. My cell bill over the past fews years has averaged about $7 or $8 a month this way since you can get discounts on the $100 refill card fairly easy.
