“T‑Mobile will never change the price you pay for your T‑Mobile ONE plan.” That was the promise. The Un-contract. The whole reason millions of customers picked the magenta team over Verizon and AT&T in the first place. Now T-Mobile is retiring legacy 3G and 4G-era plans — Magenta, ONE, Simple Choice — and automatically moving customers onto “modern” 5G plans at higher monthly costs. Billing changes hit mid-July for the current wave. The company that swore it would never surprise you with a rate hike just sent the notification.
500MB of 5G is crazy, I use double or quadruple that in a day. Great way to be forced to use your phone less I guess. One of my favorite features of recent mobile plans is truly unlimited data with deprioritization once you hit a certain limit, as I’m almost never in a location where I get deprioritized.
