It's very customizeable and for one phone it dropped to 6 bucks a month. Mind you this phone is in a car turned off for the month but nice savings.
My mom went with consumer cellular for a flip and it works for her.
Be sure to check out Republic Wireless.
I'm waiting for my new iPhone6S Plus(unlocked) purchased thru Apple. After much investigation of plans I found the big 4(AT&T, Sprint, Verizon, T-Mobile) were all to costly and not very custom fitting for my needs. I just retired, and my current phone is a 10 year old Sprint Flip. I checked out Consumer Cellular and was amazed at the wide range of customaztion, even separating phone from data/text. My own plan will be 250 minutes and 500mb for less than $25 a month. I can change at anytime. Sure my iPhone unlocked cost around a thousand dollars, but for customizing and the long run it will be great. Hint to big4: Let customers CUSTOMIZE! Well, I'm just sayin'......Bye.
