Why am I unable to send an SMS with the content of my choice? I get demo content repeatedly.

This is because your account is a demo account and we have added some credits to your account for you to test our services. This demo content acts as a safety feature so that no one misuses the provided credits. 

If you are satisfied with our trial services you can activate or switch your DEMO account to a USER account by buying credits. Kindly contact your account manager or our support team for guidance.
