what cell phone service is the best and cheapest?

I think in plans there is nothing best. if it was there every body must have adopted that plan.
i think you can chose the most suitable plan for you according to your requirement. first clear what is your exact need. Do the unlimited calls you need i think if you know ur needs well then you can chose a better plan.

Well cell phone service depends on where you live. In AZ t-mobile is the best. In WV it's Sprint. So depends on who you have around you and also where you live.

I have Verizon as well, and mine is $90.00 a month, and I have unlimite texting, picture messaging, but not unlimited minutes, as I have only so many and if I go over I would have to pay $0.40 a minute which is quite spendy. I don't ever go over my minutes, so that part I don't have to worry about at all. I had t-mobile at one time, but I kept getting dropped calls, so that is why I now have Verizon. I do like it, but I just wish the monthly bill weren't so high, but I deal with it, and I can do it, so it is okay. Not sure which is the cheapes one, as they are all high, if you want to know the truth about it. Take care, and happy mylotting.

I have T-Mobile unlimited plan for $100/month. Only thing I've added to that plan is a data plan for $10/month extra. I do get a 15% discount. Whole bill after taxes & fees comes out to around $107/month. I used to have blackberry & plan for them are little different so I used to pay little more but not by much. May be around $20 more. My bill hasn't changed little over 2 1/2 years.
