In my city 90% of the time it’s perfectly fine. Then there are a few dead spots in the t mobile network that are really frustrating and I’m usually in those spots once a week.

Then I visited some family in Colorado and it was awful and my phone was essentially useless without Wi-Fi. T mobiles network is very hit or miss but no way am I paying $70 / month or whether the going rate for Verizon, etc.
