I am using NEXMO API for integrating SMS functionality for my stuff. However I am getting the error as "Unroutable message - rejected" I don't understand what's wrong with my source code. Actually I want to send SMS on Indian as well as Nigerian numbers, and I would like to mention that both numbers are free of DND service. Do you have any idea guys which the primary setting is need to do for sending SMS. [Currently I have created a test account on NEXMO].Is their any limitations while using test account ?
This might help others if they stumble upon this problem...
If you are using a trial account, you must add test account phone numbers using the API dashboard:
API Settings -> Edit -> Add Number (bottom of page)
Cheers
