“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.
They did, but even beyond that, the other alternatives mentioned in this thread are MVNOs that still use T-Mobile’s network (usually with a lower priority compared to direct customers, not usually an issue unless there’s congestion). You’re still paying T-Mobile, just indirectly. MVNOs buy in bulk and try to offer options that split that bulk usage up in ways different to the big carriers to target smaller more specific demographics.
Isn’t this really hard to avoid in the US because of the existing infrastructure? All of the towers are owned by one or two companies, and the rest have to rent them out.
