It’s safe to say T-Mobile’s latest efforts aimed at migrating Sprint customers and integrating the “Now Network’s” mid-band spectrum to improve capacity and boost speeds didn’t go particularly well, but it actually pays off to stick with the soon-to-be-retired carrier a little longer.
That’s because existing Sprint subscribers can now add a line of unlimited service to their accounts at absolutely no charge without doing… much of anything (via Slickdeals). All you need is a wireless account opened prior to June 17 with at least one active voice line on it.
