There are two ways to send an SMS message using CentSMS:

1. Via email;  send an email from the email account you registered with CentSMS to <phonenum>@centsms.com, where <phonenum> is the phone number you want to send the message to.  Note that the subject line of your email will NOT be delivered as part of the message; only the body of your email will be send via SMS.

2. Via API: Our API documentation can be found here:
