How to cancel Tre Mobile by mail
Gather your account details
Check the account number, the phone number or service address being cancelled and the name on the account before anything else. A request that does not match the account on file at Tre Mobile is the easiest one to set aside.
Prepare the letter
Postbye drafts the request in Italian, the language of Italy, with “Oggetto: Richiesta di cancellazione – [your name]” as the subject line. It asks Tre Mobile to close the subscription, stop billing and confirm in writing.
Post it with proof of delivery
Use certified mail for the 20145 Milano address in the next section, so the post office records the delivery. Write down the tracking number.
File the delivery record
It shows the date Tre Mobile received your letter. Check your next statement: no Tre Mobile charge should post after the cancellation date.
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.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
