If you are a long-time T-Mobile customer on a Simple Choice, ONE, or Magenta plan, your bill is about to change whether you like it or not. T-Mobile has confirmed the largest forced plan migration in the carrier's history, moving more than 8 million customers onto a new set of plans called Experience tiers starting mid-July. Text messages began going out to affected customers on June 29, and the changes land on your next billing cycle after July 13.
What Is Changing and How Much Will It Cost
T-Mobile is framing this as retiring plans built nearly 15 years ago in the 3G and 4G era, long before the carrier's 5G network was fully deployed. The official line is that the average adjustment works out to around $4 per line. The actual breakdown is less gentle. Voice lines go up $6 per line, watch and tablet lines increase by $3 per line, and 5G Home Internet subscribers face a $6 bump. For a family with four paid voice lines, that is $24 more per month, or $288 per year. The popular Kickback promo on the ONE plan, which gave customers $10 off per line for staying under 2GB of data, is also ending.
Affected customers are being moved to one of several new Experience plans: Experience Signature, Experience More, and Experience Beyond, each with multiple pricing sub-tiers labelled A, B, and C. Which plan you land on depends on your current plan, and customers cannot voluntarily choose their tier. You get what T-Mobile assigns you. Free lines carry over to the new plans and are not subject to the price increases, which is about the only silver lining here.
In total, T-Mobile has introduced over 62 new plan codes for this migration while retiring more than 1,100 legacy billing codes, according to the carrier's COO Jon Freier. T-Mobile did quietly lower prices on most of the new plans by around $5 per line between Monday and Tuesday, possibly in response to the backlash, but the increases remain significant for many customers.
The Bigger Picture
This is the third significant policy tightening from T-Mobile in 2026. The carrier cut device promotion limits from four lines to two in early April, then began migrating Magenta Plus and MAX subscribers to Go5G Plus without an opt-out. This latest move reaches further back, pulling in customers on plans dating to 2013 and affecting a far larger base. The "Un-carrier" identity that T-Mobile built its reputation on under John Legere has been quietly retired alongside those plans.
The timing is not great for T-Mobile either. Verizon launched its new Simplicity prepaid plan just days before this announcement, and AT&T has been running targeted switching campaigns. Eight million newly repriced customers reconsidering their options is a significant pool to hand to your competitors, especially heading into the fall phone launch season when the first adjusted bills will be landing.
What Should You Do
If you have received a migration text, the changes do not take effect until mid-July, which gives you a couple of weeks to review your options. If you are open to switching, now is a reasonable time to compare what AT&T, Verizon, and prepaid MVNOs are offering. If you are staying with T-Mobile, check your account once your new plan is assigned and make sure the pricing matches what you were told to expect.
