Turkey is one of the markets where SS7 does not work properly and can be expensive to deliver SMS.
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.
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 traffic is forbidden by the operators and so any traffic of this type is unlikely to be delivered.
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:
Handset delivery receipts are supported.
Turkcell cannot terminate SMS to their subscribers in any other roaming network so delivery to handsets roaming internationally will fail.
