What T-Mobile doesn't put on the comparison page
T-Mobile billing warning
T-Mobile's 'free roaming' runs at 128kbps (2G speed). Loading a web page takes 30+ seconds.
T-Mobile advertises free international roaming on Magenta plans, but the included data runs at 128kbps. That is genuine 2G speed from 2003. A single web page takes 30-45 seconds to load. Google Maps barely functions. Video calls will not connect. Even WhatsApp voice notes take minutes to send. The International Pass add-on costs $10/day for usable speeds. A travel eSIM provides full-speed local data for a fraction of the cost.
You arrive abroad expecting free data. Your phone shows a data connection. Nothing loads. You realize 128kbps is not functional for modern apps.
