While everyone knows that all wireless carriers are universally terrible, I've actually had a fairly noneventful (read: good) experience with T-Mobile over the last decade. I've never observed evidence of traffic shaping or any other shady business (like capturing NXDOMAIN DNS responses and directing you to a sponsored search page). I've also never observed significant performance degradation from congestion-based prioritization after exceeding the alloted 50 GB or whatever of monthly "normal-priority" data usage.
