How to Cancel Boost Mobile in 2026

Updated February 2026 · Difficulty: Easy · $25-60/mo

✅ Prepaid = Easy Cancellation

Boost Mobile is prepaid — no contracts, no early termination fees. The simplest cancellation method: stop paying and service ends when your current period expires. Want to keep your number? Port it to a new carrier first.

How to Cancel

Port Your Number Out (Recommended)

Get your Boost account number and transfer PIN — call 1-888-266-7848 or check the Boost app
Sign up with your new carrier and provide these credentials during activation
The port takes 1-4 hours — Boost cancels your line automatically when complete
No need to contact Boost separately

Stop Paying

Don't make your next payment. Service stops at the end of your billing cycle. Boost holds your number for 60 days — you can reactivate within that window. After 60 days, the number is gone.

The Sprint-to-T-Mobile Transition

Boost was originally a Sprint brand. After T-Mobile acquired Sprint in 2020, Boost was sold to DISH Network (now EchoStar). Boost now uses T-Mobile's network under an MVNO agreement. This means:

Better coverage than the old Sprint network in most areas
Data deprioritization — Boost customers get lower priority than T-Mobile postpaid during congestion
Old Sprint-only phones may not work — check compatibility at boostmobile.com
DISH/EchoStar is building their own 5G network, but it's still years from nationwide coverage

Why People Leave Boost

Speed throttling: Boost caps video streaming to 480p (SD) on most plans
Store quality varies: Many Boost stores are independent dealers — service quality is inconsistent
Price increases: Plans have crept up from $25 to $30-35 for comparable data
Account security concerns: Multiple reports of unauthorized SIM swaps at Boost stores
Billing confusion: Auto-pay, Bridge Pay, and re-boost options can lead to unexpected charges

Alternatives

Mint Mobile ($15-30/mo): Same T-Mobile network, often cheaper with annual prepay
Cricket ($30/mo): AT&T network, better coverage in some areas, multi-line deals
Visible ($25/mo): Verizon network, unlimited everything
Tello ($10-25/mo): T-Mobile network, build-your-own plan, great customer service
T-Mobile Prepaid ($25-50/mo): Same network as Boost but with higher network priority

💡 Boost vs. Mint on the Same Network

Both Boost and Mint use T-Mobile's towers. Mint's 12-month plan ($15/mo = $180/year) is often cheaper than Boost ($25/mo = $300/year) for similar data. That's $120/year savings for the same coverage. The tradeoff: Mint requires upfront annual payment, Boost pays monthly.
