T-Mobile customers on older plans beware: the company is raising prices by up to $5 per line per month. This move comes after years of T-Mobile boasting about keeping prices low, so it’s a significant shift for the carrier.

The increase applies to some of T-Mobile’s most popular legacy plans, including One, Magenta, Magenta 55 Plus / Military, and Simple Choice. Some Go5G 55 plans aimed at seniors are also affected. However, the exact list of impacted plans remains unclear.

T-Mobile is notifying affected customers, a “small fraction” according to the company, directly. These notifications started on May 22nd, and the price hikes will appear on bills as early as June 5th. The increases vary depending on the plan, with some seeing a rise of $2 and others $5 per line.

There’s a silver lining for some. Customers on newer Go5G plans and those covered by T-Mobile’s Price Lock guarantee are safe for now. However, the terms of the Price Lock have recently changed. While it still protects existing prices, those who switch plans or activate new lines after January 18th, 2024 can now leave the contract penalty-free if a future price increase is too much to swallow.

This move by T-Mobile marks a potential turning point for their pricing strategy. While they claim it’s necessary to “respond to rising costs,” it breaks a long-held promise of price stability for many customers. It’s also worth noting that T-Mobile is quietly raising prices on some Go5G plans for new customers, suggesting a broader shift towards higher costs.

Here’s the key takeaway:

• If you’re a T-Mobile customer on an older plan, check your notifications and next bill for potential price hikes.
• Newer Go5G plans and those covered by the Price Lock guarantee (with some conditions) seem to be safe for now.
• This price increase could be a sign of more to come, so keep an eye out for future changes from T-Mobile.
