At the end of a month of service my bill is $45, whereas my previous carrier was $37.50 flat rate for unlimited voice, text and 2.5 GB of internet. I did have to use much more voice and text than usual because I am looking for a new place to live. Also, the data connection kept auto-updating apps before I realized how much bandwidth it was using. Then the wifi would auto activate and run down the battery. So it's my fault.
It's all about managing use. I seldom talk more than 500 mins/mo or text at all. I could connect to wifi to make voip calls and do other web business to keep the bill down to $25/mo. All in all I am happy with Ting, especially because of their CSRs.
