Constraints

• No images can be sent with SMS.

• With this API, messages can only be sent to mobile phones registered in the Netherlands. So the country code is locked to +31. Also 097 range is allowed.
  Note: 060xxxxxxx, 067xxxxxxx and 069xxxxxxx are not valid mobile numbers.
• A single message can be sent to a single recipient. Bulk messaging will be added in the future.
