Cost Estimate
The 24-hour customer service window
When a user sends a message to your number, a 24-hour window opens during which you can reply at no additional cost. This window resets each time the customer writes.
Within 24 hours
You can reply freely with any type of message. There is no charge for the reply.
After 24 hours
You need to use a Meta-approved template message. This has a cost.
Business-initiated messages
Messages you send first (without the customer having written before) always require a template and have a cost.
