Just about one year ago, I completely upended my mobile cell service. After 10 years of being a T-Mobile customer and becoming fed up with rising prices and a degraded user experience, I decided enough was enough and left T-Mobile for Visible.In the year since then, I’ve had a great experience with my new service provider. Visible has been fast, reliable, affordable, and generally given me nothing to complain about. Yet I’m moving on to something else — and saving $660 in the process.
