Sending SMS messages is easy
SMS messages with a 'from address'

From address. Identification.

You can set a from address to let recipients easily identify who a message is from. The originator can include up to 11 alpha-numeric characters, such as your company or brand name. 

Track messages. Your app responds.

Our Push Notification service allows your apps to receive automatic updates when a message has either arrived at its destination, failed to reach its destination or you have received a message from somebody else.  Alternatively, you can simply request the current status of messages at any time via our API or Echo, our web-based platform.
