T-Mobile just announced a handful of upcoming changes to a few of its unlimited plans. Journalists covering the news are praising the carrier’s decision to offer unlimited Premium Data on the Magenta MAX plan. I think these journalists are falling victim to the bullshit T-Mobile filled its press release with:
Let’s unpack that.
First, T-Mobile is giving way too much credit to 5G. Most of T-Mobile’s customers don’t even have 5G-compatible phones. Premium Data is still available to customers limited to 4G connections.
Second, deprioritizing ultra-heavy data users is a pretty efficient way for network operators to manage resources. Under the usual 50GB-ish per month thresholds, only ~1% of unlimited plan subscribers use enough data to get deprioritized. Users that T-Mobile deprioritizes will experience slower speeds when network resources are under heavy demand. However, deprioritized users can still experience normal speeds when networks aren’t under a heavy load. According to T-Mobile’s own website, deprioritization usually doesn’t have practical consequences (emphasis mine):
I guess you could say T-Mobile’s Premium Data is only useful in “some parts of some cities.”
The utility of Premium Data hinges on how much Premium Data is being used by other network users. By including unlimited Premium Data with the Magenta MAX plan, T-Mobile is slightly degrading service quality for tens of millions of users in order to improve service for a tiny fraction of the company’s heaviest data users. In my view, it’s a bad tradeoff from a network management perspective. T-Mobile is choosing to make the tradeoff because it gives the company a new perk to advertise on its most premium plan.
