How to cancel 1Mobile by mail
Get your account details together
1Mobile will look your account up from what the letter says, so check the name and email on the account and, if you have one, an account or customer number first.
Write the cancellation request
1Mobile is based in Italy, so the letter goes out in Italian, built from our Italian template. Subject line: “Oggetto: Richiesta di cancellazione – [your name]”. It asks for the subscription to end, for further charges to stop and for written confirmation.
Send it by certified mail
Take the letter to the post office and ask for certified delivery to 20121 Milano. Keep the tracking number it gives you.
Keep the delivery receipt
The receipt dates your request. Look at your next statement for any 1Mobile charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your 1Mobile cancellation letter goes
Written requests to 1Mobile go to Piazzale Biancamano 8, 20121 Milano, Italy.
Copy the postal code 20121 exactly: it is what routes the letter to Lombardia, Italy.
Inside, the salutation reads “A chi di competenza,”, followed by your details under Titolare dell'account, Indirizzo di fatturazione registrato and Email registrata.

Before you cancel 1Mobile, check these
- Check your next statement: no charge should appear after the cancellation date.
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

How cancelling by mail works
Subscriptions renew automatically, and a written request is the clearest record that you asked to stop it before the next billing date.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
