MESSAGE CREDITS. Additional Message Credits for SMS Text, Email & Phone calls when your issued amount of 200 have been exhausted.
WHAT IS THIS FOR? Some locations request advanced transmission of data, beyond our normal operation. Such as once a minute, once an hour, etc. This could be required for monitoring temperatures of medicines or a pharmacy. These extra credits are for those locations that will be sending thousands & thousands of data bits to be stored/monitored. These fees would be encountered by normal users if you exceeded 200 notification credits per year---which is very rare.
