“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.
there must be a workaround. I have been seeing solutions for this in the past, but I don’t remember because I haven’t had such a shitty provider.
probably it’s the TTL value in the packets. if you can move the sim card or a clone of it into a portable openwrt router, that’s an easy fix, otherwise it would probably need patching android which you probably can’t do because graphene is too hostile to that.
