If none of the SMS API's in Contact Reach work in your country (not able to send SMS), it's definitely not the end of the world.
You can consider these 2 options:
- Target prospects in countries where an SMS API works - for instance: US, UK, Canada..
- Use emails only. The software is not limited to using only SMS to send campaign messages to users. It also uses emails using Email API's. The Email API's are working for all countries as long as there's internet.
