Register your caller ID profile

In order to send text messages, you must complete registration of the sender number profile. Try setting the sending number of text messages provided by DFINERY to the brand number.

Due to the implementation of the pre-registration system for sender numbers, SMS sending from numbers that have not been registered in advance will be restricted as of October 16, 2015. Therefore, you must register your sender number in advance in order to send SMS. The pre-registration system for sender numbers is a system that prevents damage to users due to falsely displayed phone numbers in accordance with Article 84 of the Telecommunications Business Act, which allows users to send text messages only to pre-registered sender numbers.
