TMobile at one point charged me $15 every time my phone pinged a tower in a foreign country. They disconnected my account after $1200 in charges and only notified me by sending snail mail to my address on a different continent asking to call them with my now-disconnected phone. "Excellent" is not the word that comes to mind, especially given their constant security breaches. I'm on fi now and hoping Google forgets it exists so they don't cancel it.
