In what countries does Yelo work?
There isn't a straightforward answer to this question.
Email and Facebook notifications of incoming calls and SMS should work everywhere.
To make calls should also work from almost all countries.
The call forwarding functionality is the tricky part!
For call forwarding to work there are two factors that have to be taken into account.
1. Twilio needs to have numbers available in your countries. Check here
2. Operators must provide critical call data for call forwarding to work
This second part is the most tricky. What happens is that Twilio relies on the SIP Diversion Header
and some operators are not compliant and when that happens, we can't provide this functionality.
For our experience, most operators from UK, Romania, Hong-Kong, Latvia, Brazil, Greece, New Zeeland, Ireland, Germany, Bahrain, and France are NOT
compliant and call forwarding won't work.
On the other hand, most operators DO work in countries like US, Canada, Republic of Ireland, Portugal, Spain, Italy, Netherlands, Lithuania, Czech Republic.
On others like Mexico or Australia it depends on the operator.
