How to cancel Netgsm by mail
Gather your account details
Before writing, collect the account number, the phone number or service address being cancelled and the name on the account. Netgsm can only act on a request it can match to an account.
Draft the request
Netgsm is based in Turkey, so the letter goes out in Turkish, built from our Turkish template. Subject line: “Konu: İptal Talebi – [your name]”. It asks for the subscription to end, for further charges to stop and for written confirmation.
Send it by certified mail
Send the letter to the Yenimahalle mailing address shown below by certified mail. Keep the tracking number safe.
Keep proof the letter arrived
The receipt dates your request. Look at your next statement for any Netgsm charge after that 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.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
