Turkey

Turkey is one of the markets where SS7 does not work properly and can be expensive to deliver SMS. 

Sender ID:

Dynamic Sender ID is not supported and will be changed to a random numeric or alpha Sender ID in order to ensure delivery. If you need to pre-register your Sender ID, please contact your Account Manager.

Content:

Marketing content:

There are special rules for all marketing/advertising messages imposed by the Turkish Telecom Regulator, which must follow the below guidelines:

- The short messages (SMS) must be prefaced with "REKLAM:" or "TANITIM:", thus telling end-user know that he/she is receiving an advertising or promotional message.
- The SMS should include URL address or company customer care number, informing the recipient of where he/she can find details of the promoted campaign / promotion.
- The SMS shall end with an opt-out option (such as “To unsubscribe text CANCEL to xxxx”).

Example of an acceptable Promotional message:
TANITIM: [BRAND]’da %50’ye varan indirim başladı. Mağazalarımıza bekliyoruz. Çıkmak için yaz 3525’e gönder:

[BRAND] : Veritabanımızdan çıkma talebiniz 3 iş günü içerisinde işleme alınacaktır. Teşekkür ederiz. 

(Translation:Your opt-out request will be processed within 3 working days. Thank you.)

Gambling content:

Gambling traffic is forbidden by the operators and so any traffic of this type is unlikely to be delivered.

Unicode:

Unicode is supported.

Please note that if you wish to send messages using Turkish accents (Ğ İ Ş ğ ı ş Ð Ý Þ ð ý þ), you will need to send your messages in Unicode format, as Turkish accents are outside the GSM character set.

Other features/restrictions of note:

Delivery Receipts:
Handset delivery receipts are supported.

Roaming:

Turkcell cannot terminate SMS to their subscribers in any other roaming network so delivery to handsets roaming internationally will fail.
