How to cancel Syma Mobile by mail
Start with your account details
Syma 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.
Put the request in writing
Syma 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.
Mail the letter with a receipt
Post it by certified mail to Syma Mobile in Paris, France, using the exact address below, and note the tracking number.
File the delivery record
Keep the tracking record with your copy of the letter. If Syma Mobile bills you after the date it received the request, you have the dates to point to.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Syma Mobile cancellation letter goes
Syma Mobile lists Rue du Général Alain de Boissieu 16, 75015 Paris, France as its mailing address.

Cancelling a phone or internet plan
