Of course one phone would cost half what my bill is. My mobile bill for two phones has stayed at about $23, including unlimited Internet.
TING.com charges per use, so if I go over my first 100 minutes, it’s $9 for 500 minutes instead of $3 for 100 minutes: you use as much as you decide that you need to use never getting “limited” or cut off.
They do what they say: we’ve had it since August 2016. Coverage is good. No actual problems that I remember.
If this is cheaper than you have now, and you want to change, you can use my link below and you will get a $25 credit (to pay your bill a couple months or to buy a new phone). Here’s my link: https://zaohqc5lpjf.ting.com/
