T-Mobile Is Forcing 8 Million Customers Off Old Plans — What to Do Next
If you've been happily riding a grandfathered T-Mobile plan for years, your ride is ending. On June 29, 2026, T-Mobile began notifying customers that it's retiring its legacy plans and automatically moving people to its newer Experience plans — no opt-in required, and no way to keep your old plan.
Here's everything we know, what your options are, and one thing most articles won't tell you: what to do with your old phone if you decide to jump ship.
Who's Affected
Roughly 8 million customers are being migrated, according to reporting from The Mobile Report and 9to5Google. The affected plans include:
- Simple Choice (the classic ~2013-era plans)
- T-Mobile ONE and ONE Plus
- Magenta family plans
- Grandfathered Sprint plans you kept after the merger
- Some T-Mobile for Business accounts
If you're on a Go5G plan (or already on an Experience plan), you're not part of this migration.
Not sure which plan you're on? Open the T-Mobile app or check the top of your bill. If you see any of the names above, expect a notification — T-Mobile says affected customers get about two weeks' notice before the change hits.
What's Changing
- You'll be moved to a newer "Experience" plan automatically. T-Mobile says the goal is to simplify — internally it's reportedly juggling over a thousand old rate plans, some designed back in the 3G/4G era.
- Most price changes land between $0 and $6 per line. T-Mobile says roughly half of affected customers will see no increase. For the rest, reported increases run about $4 per line on average, up to $6 per voice line, $3 for watch and tablet lines, and $6 for 5G Home Internet. For a family of four, that can add up to roughly $24 more per month.
- Timing: changes take effect on bill cycles starting mid-July 2026.
- Some perks disappear. The old ONE-plan "Kickback" credit ($10 off a line that used under 2GB in a month) is going away.
- You get a new promise in return: the Experience plans carry T-Mobile's 5-year price guarantee on talk, text, and 5G data charges.
A word on that guarantee: read it carefully. It covers the base talk/text/data rate — not taxes, fees, or add-ons. And longtime customers will remember that many of these same legacy plans were once covered by T-Mobile's older "Un-contract" price promise before prices went up anyway in 2024. Healthy skepticism is fair here.
Can You Say No?
You can't keep your old plan — there's no opt-out that freezes your current rate. But T-Mobile plans are contract-free, so you're free to leave at any time. Two things to check before you do:
- Device payments. If you're financing a phone through T-Mobile, the remaining balance is due when you leave, and any remaining promotional bill credits are forfeited.
- Unlock status. Make sure your phone is paid off and unlocked before you switch so it works on a new carrier.
If You're Thinking About Switching: The Best Alternatives Right Now
If a forced plan change is your cue to shop around, the good news is that 2026 is a great time to be a switcher. A few solid options:
Mint Mobile — the obvious first stop. Mint runs on T-Mobile's own network, so coverage will feel identical to what you have now — same towers, lower bill. Plans start at $15/month, and as of this writing Mint is running a promotion that makes every plan — including Unlimited — $15/month when you prepay a 3, 6, or 12-month term. The trade-off: you pay upfront for the term, and — full transparency — Mint has actually been owned by T-Mobile since 2024. If your goal is a lower bill on the same network, it's hard to beat. If your goal is to quit T-Mobile entirely, keep reading.
Visible (Verizon) — unlimited data on Verizon's network in the ~$25/month range, no stores, everything handled in the app. A good pick if you want off T-Mobile's network altogether.
US Mobile — the flexibility play. It offers plans on all three major networks and lets you switch networks if coverage disappoints, with unlimited options also in the ~$25/month range.
Metro by T-Mobile — T-Mobile's own prepaid brand, with in-person stores if you prefer to handle things face to face. Same network, generally lower prices than postpaid.
Whichever you choose, bring your number with you (it ports in minutes these days) and check each carrier's coverage map for your address before committing.
Switching Carriers? Don't Let Your Old Phone Ride the Bench
Here's the part of the switch almost everyone leaves money on the table with.
New carriers love to dangle trade-in deals — but those deals usually pay you back as bill credits spread over 24–36 months, which quietly locks you into that carrier for years. Leave early, and the remaining credits vanish. That's not a deal; that's a leash.
We'd rather just hand you cash.
At Cell Me Your Phone, we buy phones outright — cracked screens, old models, drawer phones, all of it. No bill credits, no strings, no 36-month commitment. You get paid, and you stay free to chase the next great carrier deal whenever you want.
If you're using this T-Mobile shake-up as your excuse to switch carriers and upgrade your phone, do the math: an unlocked, paid-off phone sold for cash often beats a locked-in trade-in credit — and it definitely beats letting your old phone depreciate in a junk drawer.

The Bottom Line

- You can't keep your old plan, but you can leave anytime — plans are contract-free.
- If you switch, providers like Mint Mobile, Visible, US Mobile, and Metro offer serious savings.
- And if a new phone is part of your switch: sell us your old one. Cash today beats a three-year trickle of bill credits.
