3. SMS Messaging

4. Live Transfers
-
Each call leg (inbound caller, outbound transfer) is billed separately.
-
A transfer means two active call legs, effectively doubling costs.
-
Example: A 5-min call + 3-min transfer = 8 billed minutes.
Overall:
Twilio uses a pay-as-you-go model with per-number monthly fees, per-minute/per-text usage fees, and add-on costs for features like media streams, answering machine detection, and call recordings. Live transfers are the most expensive scenario since they duplicate call legs.
