Turkey is one of the markets where SS7 does not work properly and can be expensive to deliver SMS.
Sender ID:
Alpha Senders can be preregistered (following specific requirements) after customer's request.

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 NX[BRAND] yaz 3525’e gönder.
In this case, were the user to unsubscribe by sending "NX[BRAND]" to 3525, where BRAND is the sender of the advertising SMS, , the end-user would receive the following MT confirmation in response (this response will be managed by Nexmo):
[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.)
There are no other additional content restrictions beyond those in our Acceptable Use Policy
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.
