Per message segment, 10DLC. Your provider adds its own markup.

What is a carrier fee?

When a business sends a text, the carrier that delivers it charges a fee for each message. Your provider, such as Twilio, adds this fee to your invoice on top of its own price. That is why it is called a pass-through fee.

The fee is per segment, not per message. One segment holds up to 160 characters, or 70 when the message has an emoji or other special characters. A 200-character text is 2 segments and pays the fee twice. “SMS out” is a message you send. “SMS in” is a reply from your customer.

Example: 10,000 two-segment texts to Verizon customers are 20,000 segments × $0.005 = $100 in carrier fees.
