How to cancel Allianz Sim by mail
Find 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 Allianz Sim is the easiest one to set aside.
Write your request
Postbye writes the letter in German from our German template, because Allianz Sim's address is in Austria. It opens with the subject line “Betreff: Kündigungsanfrage – [your name]” and asks Allianz Sim to end the subscription, stop all further charges and confirm in writing.
Mail the letter with a receipt
Post it by certified mail to Allianz Sim in Vienna, Austria, using the exact address below, and note the tracking number.
Keep the proof of delivery
Delivery confirmation is your evidence that Allianz Sim was asked. Watch the next statement or two for any further Allianz Sim charge.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Allianz Sim cancellation letter goes
Allianz Sim lists Postfach 1860, 1860 Vienna, Austria as its mailing address.
“Postfach 1860” is a post-office box or mail-sorting line, so it takes post and not couriers: certified mail is the right way to reach it.
Your name, address and email appear in a short block labelled Kontoinhaber, Hinterlegte Rechnungsadresse and Hinterlegte E-Mail-Adresse, under the greeting “Sehr geehrte Damen und Herren,”.

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 letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.
