If you’re on a T-Mobile plan called Simple Choice, ONE, Magenta, or any plan that’s been around for a few years — your plan is being retired. T-Mobile has started notifying customers, and the changes take effect starting mid-July. For most people, that means your next bill or the one after it will look different.
This is not a small change. It affects an estimated 8 million customers, and it is the largest plan migration in T-Mobile’s history.
Here’s what’s actually happening, what it means for your bill, and what you can do about it right now.
What’s Changing
T-Mobile is retiring its oldest plan structures — some dating back to 2013 — and moving customers onto a new set of plans called “Experience.” The new plans come in several tiers: Experience Signature Select, Experience Signature, Experience More, and Experience Beyond. There are also tax-inclusive versions for customers whose current plans include taxes and fees in the price.
The new plans include some additions — a five-year price guarantee, satellite connectivity through T-Satellite, and streaming bundles. But they also come with price increases for most customers.
Here’s what the increases look like based on what’s been reported so far:
Voice lines go up by approximately $6 per line per month. Watch and tablet lines increase by roughly $3. Home internet customers may see an increase of around $6. T-Mobile has said the average increase works out to about $4 per line — but that average includes the lower-cost lines. A family with four voice lines is looking at closer to $24 more per month, or roughly $288 per year.
What You Cannot Choose
One detail worth understanding: customers are not being given a menu of new plans to pick from. The plan you’re moved to is determined by your current plan, and T-Mobile assigns the specific tier and pricing sub-level. You may see an A, B, or C designation on your new plan — that’s a pricing sub-tier based on what you were paying before. It is not something you select.
If you had free lines, those carry over — your free lines should remain free on the new plan. Your tax structure should also stay the same: if your current plan is tax-inclusive, the new plan will be too.
What You’re Losing
A few things are going away that are worth knowing about:
The KickBack credit — a $10 monthly credit for lines that used less than 2 GB of data — is being removed. If you’ve been getting that credit on any of your lines, it will no longer appear.
Some legacy plan features and add-on discounts may also be affected. Customers have reported changes to data add-on pricing and other line-level adjustments beyond the base rate increase.
What to Do Right Now — Before the Change Hits
Check your notifications. If you’ve received a text, email, or in-app message from T-Mobile about your plan changing, read it carefully. It should include your specific new plan name and when the change takes effect.
Log into your T-Mobile account. There is a page on the T-Mobile website that shows any pending plan changes for your account. Look for your new plan name, the number of lines, and any pricing details available.
Download your current bill. Before the change takes effect, download a PDF of your most recent bill. This gives you a snapshot of what you were paying, what discounts were applied, and what your plan looked like before the migration. If anything looks wrong afterward, that bill is your reference point.
Write down what you’re paying now — per line. Note your plan name, your per-line cost, any credits or discounts, and any add-ons. When your new bill arrives, you’ll be able to compare line by line.
Check for a Price Lock or Un-Contract. Some legacy plans came with a price commitment from T-Mobile. If your plan included the original “Un-Contract” or a newer Price Lock, you may have specific protections when prices change — including having your final month’s service fee covered if you choose to leave within a certain window. It is worth confirming whether your plan qualifies.
What the New Plans Cost — Based on Public Reporting
Several outlets have published pricing details for the new Experience migration plans. These numbers come from community research and public reporting — not from T-Mobile directly — so treat them as a reference guide, not a guarantee of what your specific account will look like. T-Mobile has already adjusted some pricing by roughly $5 per line after the initial backlash, so these may continue to shift before July 13.
All prices shown assume AutoPay is enabled.
| Lines | Experience Signature (A) | Experience More TI (A) | Experience More TI (B) | Experience Beyond TI |
|---|---|---|---|---|
| 1 line | ~$81/mo | ~$90/mo | ~$95/mo | ~$100/mo |
| 2 lines | ~$142/mo | ~$150/mo | ~$160/mo | ~$170/mo |
| Each additional (3–8) | +~$31/line | +~$35/line | +~$40/line | +~$45/line |
These prices do not include free lines (which should carry over as fully credited), insider discounts, or other account-level adjustments. The A, B, and C sub-tiers are pricing levels assigned by T-Mobile based on your current plan — you do not choose between them. There are more than 62 new plan codes in total, including military, first responder, and 55+ variants. The table above covers the most commonly reported tiers. Pricing is subject to change before July 13.
When Your Bill Changes
For most affected customers, the new plan takes effect starting mid-July — around July 13 has been widely reported. That means your first bill under the new plan will likely arrive in August.
When that bill comes in, here’s what to check:
The plan name — it should now say “Experience” followed by a tier name. If your old plan name is still showing, the migration may not have hit your account yet.
The per-line charge for each voice line — compare this to what you wrote down. This is where the increase shows up.
Whether your free lines still show as fully credited — they should carry over, but verify it.
Whether your tax treatment changed — if you were tax-inclusive before, you should still be tax-inclusive. If taxes suddenly appear as a separate line, that is worth asking about.
Whether any old discounts or promotional credits changed at the same time — a migration can sometimes reset things that were not supposed to move.
Whether new features or services appeared that you did not ask for — streaming bundles, hotspot changes, or add-ons that came with the new plan but may affect future charges.
If something does not match what you expected, that is worth a conversation with T-Mobile. Not a confrontation — a conversation. Specific, calm, and with your old bill in front of you.
What This Means for Your Account Going Forward
The new Experience plans come with a five-year price guarantee — meaning the base plan price should not change again for five years after the migration. That is a real commitment, and it is worth noting.
But the guarantee applies to the new, higher price. And it covers the plan rate — not necessarily every fee, add-on, or line-level adjustment that might change independently.
The features included with the new plans may be genuinely useful for some customers. Satellite connectivity, additional hotspot data, and streaming bundles are real value — if you use them. If you do not, you are paying more for things that do not change your day-to-day experience.
A Quick Take
I spent 18 years managing billing and customer service operations in wireless. Plan migrations are not new — they have happened before, in smaller waves. What makes this one different is the scale (8 million customers), the speed (two weeks between notification and change), and the fact that customers do not get to choose their new plan.
For most people, the best thing you can do right now is simple: download your current bill, write down what you are paying, and compare it line by line when the new bill arrives. That puts you in a position to have a clear, informed conversation if something does not look right — instead of calling in frustrated and trying to figure it out on the fly.
If your bill changes and you are not sure what happened or why, that is exactly what ClearBillReview is built for. Upload your bills — the one before the migration and the one after — and get a plain-English report that shows what changed, what it means, and the exact words to use if you decide to call.
