I Was Wrong

I’d like to avoid hiding my mistakes and downplaying my errors. This page is a log of times I was wrong or otherwise made mistakes. It’s inspired by the mistakes page of my former employer, GiveWell.

Post About T-Mobile’s 100GB Hotspot Plan

In March of 2021, I published a blog post criticizing T-Mobile for ceasing to offer a 100GB hotspot plan just a few months after the company drew a ton of attention to the plan’s launch. My post had serious issues.

I didn’t adequately distinguish between a prepaid version of the plan that was no longer available and a postpaid version of the plan that remained available. I also, likely incorrectly, suggested subscribers who already signed up for the plan would not be grandfathered.

In the post, I quoted a Twitter user who said a T-Mobile support agent told him subscribers would not be grandfathered. While I expect the Twitter user accurately reported what he heard from a T-Mobile agent, I shouldn’t have taken the information at face value. I’ve been involved in the cellular industry long enough to know that support reps regularly give inaccurate information about carriers’ policies.

Misconfigured JavaScript

For about 24 hours in November 2021, some misconfigured JavaScript removed text intended to flag that content about a cell phone carrier was a sponsored placement.
