What SenderID can I use?

The senderID of SMS is subject to the regulation or restrictions of the carriers in many cases for the purpose of prevent spoofing. The EZSMS users can specify the senderID as their own, but please be aware that the senderID can be replaced by something else by the carriers for the reason.

We strongly recommend the users to include their names or their business names in the bodytext so that the recipients will well-recognize who is the sender of the message.
For example:

Hi, this is an ordinary clinic, .....
A message from the club Ribbon about the emergency meeting.....
