## Why was my SMS delivered as an MMS?

During peak traffic, Plivo's routing algorithm may occasionally send an SMS as an MMS to clear the queue faster and speed up delivery. To the recipient, the message looks like a regular long text SMS. You are billed only the standard SMS rate and the corresponding SMS carrier surcharge. Plivo covers the additional MMS costs and the associated carrier surcharge. For any concerns, please raise a support ticket with our team.
