Note the Open SMS Gateway that I use has some limits:
- Less than 4 SMS's to a single phone number within 3 minutes.
Less than 75 SMS's per day from a single IPA.
And, of course, SMS is limited to 160 characters per message.
The function is defined as:
boolean
page( String aMesgText = DEFAULT_PAGER_MESSAGE,
String aNumber = DEFAULT_PAGER_NUMBER,
String aHost = DEFAULT_PAGER_GATEWAY,
int aPort = DEFAULT_PAGER_PORT )
{
