How to cancel Boost Mobile by mail
Start with your account details
Boost Mobile will look your account up from what the letter says, so check the account number, the phone number or service address being cancelled and the name on the account first.
Set out the request
Ask Boost Mobile to cancel the account, stop all further charges and confirm in writing. Postbye prepares the letter from our English template, with the subject line “Subject: Subscription termination – Boost Mobile”.
Post it with proof of delivery
Take the letter to the post office and ask for certified delivery to 80112 Englewood. Keep the tracking number it gives you.
Save the tracking record
Delivery confirmation is your evidence that Boost Mobile was asked. Watch the next statement or two for any further Boost Mobile charge.
With Postbye, steps 2 to 4 take about two minutes of your time.

Cancelling a phone or internet plan
Phone and internet providers tie cancellation to contracts, equipment balances and notice periods, so the request should name the exact line or service and ask for a final bill in writing.
If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.
Boost Mobile lets you cancel directly (phone). A letter is the fallback that leaves a dated record when the direct route fails.
