Known restrictions:
Sender ID:
Dynamic sender IDs are not supported and will be changed to a random sender ID in order to ensure delivery. Numeric and generic sender IDs are also not supported.
For managed customers, quality will be improved if you pre-register your sender ID, which should be the same as your company name. Please contact your account manager to do this.
Content:
As per Turkish regulations, a short code will be added to the end of messages.
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
