Due to worldwide growth in the business-to-customer SMS messaging environment, many countries and territories have introduced SMS message sending regulations.
Regulations typically pertain to the following:
● Time of day that messages may be delivered
● Content of the messages
● Format of the Sender ID (from address) that may be used/displayed. Carriers in certain countries will block SMS messages that are sent from sender ID formats that they do not recognize or support.
Non-compliance with these restrictions may lead to non-delivery of messages, which is why you need to familiarize yourself with the restrictions and conditions applicable to the relevant countries and territories in which you are operating or to which you are sending SMS messages.
