Service is down for several hours every month. Way to expensive by the time you add on all the stuff that is useful... otherwise get ready for a shock if you ever go over the limits they set. And you can't control.
I have 2 story house and no matter how much I paid even for 2 routers, still doesn't work. Half the time, wifi isn't even on and I get extra bill from my phone provider. I tested it many times but didn't help
