Hello.
In Korea, telecommunication companies provide an additional service called dual number. Suppose I have A (original number) and B (second number), when I send a text using A, I can just send it, but when I send a text using B, I need to add a # after the recipient's phone number. For example, 010-1234-5678#. But now, when I send a text with the program, it automatically removes the # and leaves only the number. So I can't send a text using B. In conclusion, please allow me to write a # after the number. In conclusion, please allow me to write # after the number. Please see the picture.
