How to cancel La Poste Mobile by mail
Start with your account details
Before writing, collect the account number, the phone number or service address being cancelled and the name on the account. La Poste Mobile can only act on a request it can match to an account.
Write the cancellation request
La Poste Mobile is based in France, so the letter goes out in French, built from our French template. Subject line: “Objet : Demande d'annulation – [your name]”. It asks for the subscription to end, for further charges to stop and for written confirmation.
Post the letter
Use certified mail for the 95905 Cergy-Pontoise address in the next section, so the post office records the delivery. Write down the tracking number.
Keep the proof of delivery
File the receipt with the letter. A La Poste Mobile charge dated after delivery is the one to dispute, and these two documents are what you quote.
With Postbye, steps 2 to 4 take about two minutes of your time.

Cancelling a phone or internet plan
