Turkcell Mobile Signature membership comprises 3 steps: pre-application, application, and activation.

For membership, you first have to pre-apply to TEB Internet Branch. For pre-application, you will be asked for your name, surname, citizenship number, place of birth, date of birth, and the Turkcell line you will be using with your mobile signature.

After pre-application you can apply to any Turkcell Extra with an ID (driver's license, national ID, lawyer's ID, or passport) and sign the Turkcell Mobile Signature Certificate Ownership Contract.

• The owner of the Turkcell line should change his or her SIM card to SimPlus128. This will not change the GSM number.
• A few days after you visit Turkcell Extra, you will receive a call from Turkcell Customer Relations and will be asked some questions to confirm your identity.
• The Initiation Code you will use while forming your Turkcell Mobile Signature will be communicated to you over the phone and your membership will be activated.
• For your safety, do not share your Initiation Code with anyone.
• Turkcell Mobile Signature application cannot be done via a power of attorney.

Activation
