Availability of 2 way SMS for all countries / Marked as deferred- We need more information from Eightfold

Best answer by dkreiger

Hi ​@Juvy,

 

What i see from our docs is: 

  • Eightfold does not officially support global two-way SMS end-to-end as a guaranteed capability (availability can vary by Twilio limitations and local carrier regulations).
  • Two-way SMS is supported in Eightfold via Twilio webhooks (candidate replies route into Eightfold).
  • The docs explicitly say to refer to Twilio’s SMS guide to verify whether two-way SMS is supported for the intended countries. 

 

Countries explicitly reported as supporting two-way SMS in Eightfold

The documentation lists (non-exhaustive):

  • South Africa (+27) 
  • Netherlands (+31) 
  • Belgium (+32) 
  • France (+33) 
  • Austria (+43) 
  • United Kingdom (+44) 
  • Denmark (+45) 
  • Chile (+56
  • Australia (+61) 
  • Finland (+358) 
  • Israel (+972) 


Important caveats for “worldwide”

  • In some countries, recipients may receive SMS from a US number but cannot reply (i.e., not two-way).
  • As a best practice, Twilio recommends using a local number wherever two-way SMS is needed.

 

I hope this was helpful, Please let me know otherwise.
