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 USER account by buying credits. Kindly contact your account manager or our support team for guidance.
