2. Why I started with it?

3. We had a problem
We needed a phone support 24x7 in case the
website becomes unavailable and other
possible urgent issues.

6. Solution
We decided to use a Communication as a Service (CaaS) to
register a fixed phone number in Brazil, which receives a call
and redirects it to the developer on duty cellphone.

8. Why Twilio?
• No Contracts
• Pay as you go
• Simple and well documented API

9. Brazilian pricing
• To receive a call = 1¢/minute
• To make a call = 33¢/minute
• To send a text: starts at =1.2¢/message
• Fixed brazilian number = 3$/month
• Fixed american number = 1$/month
