You’re sipping your morning coffee, scrolling through your phone, when a text pops up from T-Mobile. It’s not a cheery “thanks for being a loyal customer” message or a heads-up about some shiny new perk. Nope. It’s a notification that your bill’s about to go up—$5 more per month, per line, starting April 2nd. If you’re one of the folks on T-Mobile’s older legacy plans, this might sound familiar. The news broke this week, and let’s just say the vibe on Reddit’s r/tmobile community is less “yay, 5G!” and more “ugh, not again.”

According to a report from 9to5Google, T-Mobile has started rolling out these price hikes to select customers on its legacy plans—those cherished relics from the days when unlimited data didn’t come with quite so many asterisks. The carrier’s been tight-lipped about exactly which plans are getting hit, but the buzz online suggests it’s a mixed bag of older offerings that have been around longer than some of the newer Go5G-branded options. Posts on Reddit show a flurry of users sharing screenshots of the text messages.

So, what’s the deal? Why now? Well, T-Mobile’s consumer group president, Jon Freier, spilled some of the tea in an internal memo that CNET got their hands on. Apparently, it’s all about “rising costs.” Inflation’s been a buzzword for a while now—everything from gas to groceries has taken a hit—so it’s not a huge shock that a telecom giant might feel the pinch too. Freier’s memo, dated around mid-March 2025, reportedly says the company’s notifying affected customers by the end of the day on March 13th. The goal? Wrap up a round of price adjustments that started last year and, in T-Mobile’s words, keep the business humming along.

Here’s where it gets a little murky: not every legacy plan is in the crosshairs. CNET notes that newer plans like Go5G, Go5G Plus, and Go5G Next are safe from this particular hike. Meanwhile, some of the older plans already saw increases of $2 to $5 back in 2024, and Freier’s memo supposedly promises that if your line got bumped up last year, you’re in the clear this time around. Think of it like a “one and done” deal—at least for now.

Over on X, T-Mobile’s support account has been doing damage control, reassuring folks that “most customers are not included” in this change. “We’re wrapping up the price adjustments that began last year in response to rising costs,” the account posted earlier this week. “We are still committed to providing low prices and the most value across all plans.” They also threw in a lifeline for the worriers: if you’ve got Price Lock on your account—a feature T-Mobile’s touted as a shield against rate hikes—you should be golden.
