T-Mobile Legacy Plans: Simple Choice, One & Migrated Sprint

T-Mobile isn’t just repricing these — it is retiring them and moving customers onto current plans automatically, at an average of about $4 more per line. The question is no longer whether to leave, but what to move to.

The plans were retired. The migration came after.

Verizon and AT&T legacy holders are mostly deciding whether a good old plan still beats a good new one. T-Mobile legacy holders don’t get that choice. T-Mobile is retiring its oldest plans outright — Simple Choice, ONE, ONE Plus, the Magenta family, and grandfathered Sprint plans — and migrating those customers onto current plans automatically. T-Mobile says the average adjustment is about $4 per line, and that there is no path back to the old plan.

Key takeaways
T-Mobile is retiring these plans, not just repricing them — migration happens automatically at about $4 more per line on average.
Covers Simple Choice, T-Mobile One, Magenta, Go5G, and migrated Sprint plans.
Experience More is $85/mo with taxes included; Mint renews at $40/mo on the same network and is T-Mobile-owned.
Keep it for sub-$40 all-in rates, legacy multi-line pricing, or a discontinued perk you actually use.
Sprint-migrated accounts vary — get your specific protections in writing before changing anything.

Which plans this covers

  • Simple Choice — the pre-One lineup, with data tiers rather than bundled unlimited.
  • T-Mobile One — the taxes-included unlimited plan that replaced Simple Choice and was itself replaced.
  • Magenta and Magenta MAX — later tiers, now superseded by the Experience lineup.
  • Go5G tiers — the most recent retirement, closed to new customers when Experience launched.
  • Migrated Sprint plans — Sprint customers moved onto T-Mobile's network keep plan names that no longer exist in either lineup.
This is a migration, not a price notice
T-Mobile is retiring these plans and moving customers to Essentials, Essentials Saver, Experience More, Experience Beyond, or Better Value. No action is needed for the migration to happen — it completes on its own and shows up on the next bill. T-Mobile puts the average adjustment at about $4 per line and says migrated customers keep their current benefits and gain a five-year price guarantee. Its own executives have said there is no going back to the retired plans.

Reported alongside the plan retirement: watch and tablet lines rising by about $3 per line, and 5G Home Internet by about $6. Those are separate from the plan migration and stack with it if you have those lines.

How to tell if you're affected

Reporting puts the affected base near 8 million lines, including some small-business accounts — one of T-Mobile's largest forced migrations. T-Mobile has not published a full list of retired plans, so the practical checks matter more than the announcement:

  1. Watch for a text or a T-Life app notification — T-Mobile said affected customers are alerted directly.
  2. Log in and open your billing details. Compare your current plan name and per-line rate against the plan you'd be moved to.
  3. Check the rate plan migration page in your account, which requires a login, for the specifics of your destination plan.
  4. If you've been on the same plan for years and never switched proactively, assume you're in scope until you've confirmed otherwise.
Do this before the change lands
Screenshot your current plan name and per-line rate now. Once the migration, promos, and prorated charges settle on the next bill, it becomes hard to reconstruct what you were actually paying before — and that number is the whole basis for deciding whether to stay.

Notice periods have been short — roughly two weeks between notification and the new pricing appearing on the next bill cycle. If you've been notified, treat the window as days, not months.

What replaced them

T-Mobile's current flagship structure is Experience More at $85/mo and Experience Beyond at $100/mo, both with taxes and fees included — which is the one genuinely useful thing about T-Mobile's pricing, because the advertised number is the number. Experience More includes a 60GB hotspot.

The comparison worth running isn't only against T-Mobile's own lineup, though. T-Mobile owns Mint, and Metro is T-Mobile's prepaid brand, so both run on the same network:

  • Mint Unlimited — $15/mo on your first 3-, 6-, or 12-month term, then $40/mo. 50GB premium threshold, up to 20GB hotspot. T-Mobile-owned.
  • Metro Flex Unlimited and Flex Unlimited Plus — T-Mobile's prepaid brand with retail stores, useful if in-person support is part of why you've stayed.
  • US Mobile Unlimited Premium — $32.50/mo, choice of T-Mobile or Verizon at signup, 50GB hotspot.
  • Google Fi — worth a look only if you travel internationally; Fi Unlimited Plus includes data in 200+ countries with no day passes.

Why T-Mobile is doing this

The plans being retired were built for a 3G and 4G network that no longer reflects what T-Mobile operates, and they sit outside every pricing structure the company sells today — which makes them both an accounting nuisance and the cheapest seats in the house. Legacy customers are also, by definition, the ones who don't shop: they stayed through years of better-marketed offers. That combination is why retired plans have become the industry's preferred place to find revenue, and it's the honest answer to "why now" — not the network-modernisation framing in the announcement.

The honest case for keeping it

  • Your all-in rate after the increases is still below $40 a line and you use a meaningful amount of data.
  • You have multi-line legacy pricing — old T-Mobile family and Sprint-migrated accounts sometimes carry per-line totals that current plans can't match.
  • You hold a legacy perk that's been discontinued rather than repriced, and you actually use it.
  • You're on a Sprint-migrated plan with terms that were protected as part of the merger commitments — worth confirming with T-Mobile what specifically applies to your account.

The honest case for leaving

  • You are being moved regardless. The only decision left is whether the destination plan is the best available, and T-Mobile picks that for you if you do nothing.
  • You're paying more than $40 a line, where Mint's renewal rate matches you on the same network — and $15/mo for the first term undercuts everything.
  • You want taxes-included pricing, which Experience gives you and most legacy plans don't.
  • You're on Simple Choice with a data tier. Tiered data at current prices is the weakest position on this list.
Sprint-migrated accounts: ask first
If your plan came across from Sprint, some terms were preserved through the merger and some weren't, and it varies by account. Before changing anything, ask T-Mobile in writing which protections attach to your line — this is the one cohort where the answer genuinely differs person to person.

Frequently asked questions

Is T-Mobile raising prices on old plans? +
It is going further than that — retiring them. Simple Choice, ONE, ONE Plus, the Magenta family, and grandfathered Sprint plans are being closed, with customers migrated to current plans automatically at an average of about $4 more per line, per T-Mobile. Watch and tablet lines and 5G Home Internet have separate reported increases.
Do I have to do anything? +
No — and that is the problem. The migration completes by itself and appears on your next bill, with T-Mobile choosing the destination plan. If you want a different one, or a cheaper carrier on the same network, you have to act before that happens.
Can I go back to Simple Choice or T-Mobile One? +
No. Both are retired, and T-Mobile executives have stated plainly that returning to the old plans is not an option. Any move is one-way, so test alternatives on a separate eSIM line before you commit.
What happened to my Sprint plan? +
Sprint plans were migrated onto T-Mobile's network and keep names that exist in neither current lineup. Some terms were preserved through the merger and some weren't, and it varies by account — ask T-Mobile in writing what applies to yours.
What's the cheapest plan on T-Mobile's network? +
Mint Unlimited at $15/mo for your first 3-, 6-, or 12-month term, then $40/mo. Mint is owned by T-Mobile and runs on its 5G and 4G LTE network, including Ultra Capacity where available.
Is Experience More worth $85? +
Its distinguishing feature is that taxes and fees are included, so $85 is the actual bill — which makes it directly comparable to all-in MVNO pricing in a way most postpaid plans aren't. It also includes a 60GB hotspot. Whether that beats $40 Mint depends entirely on how much you tether.
Will I lose my legacy plan if I upgrade my phone? +
Buying outright or bringing your own device generally preserves it; financed and promotional upgrade paths often require moving to a current plan. Confirm before ordering, in writing.
