I just switched to the T-Mobile ONE 2 for $100 plan for one specific reason: the no-cost upgrade from 128 kbps to 256 kbps for international data roaming. I completed this change on 4/8, and 10 minutes later I got in contact with customer service to enact the no-cost upgrade. According to customer service, this was a promotion that ended 4/7, and I'm now being told it costs $5 per month.
This is entirely contrary to what is CURRENTLY listed in the ONE Plan terms and conditions that I was presented with upon the plan change. It's also contrary to what is listed (as of 4/8) in the international roaming section of the T-Mobile site (see https://www.t-mobile.com/customer/Op16063SG.html), What can I do at this point? I feel like this was entirely bait-and-switch. I’m paying $20 more per month now, and I have exactly zero benefit under the ONE Plan.
It's also still under the main LTE page. See the fine print: 4G LTE Network | 4G Network Built for Unlimited Coverage | T-Mobile
Simple Global: Usage may be taxed in some countries. Calls from Simple Global countries over Wi-Fi are $.20/min. (no charge for Wi-Fi calls to US, Mexico and Canada). Activate no-cost upgrade for approx. 256 kbps speeds; standard speeds approx. 128 Kbps.

It looks like social media customer service was able to fix this issue for me.
If anyone from TMo is reading, I'd recommend scrubbing the fine print to find where this promotion is still advertised. It's still out there, and there could be other dissatisfied customers learning that the promotion isn't valid.
