Over the next few weeks, we are gradually rolling out MMS capabilities across our US Toll-Free numbers.
Starting this week, you will see numbers with MMS capabilities appear when you search for US(+1) Toll-Free phone numbers using Advanced Search. If you already own Toll-Free numbers, they will be enabled with MMS capabilities by the end of March as well.
You can send an MMS message on a Toll-Free number by including the MediaUrl parameter in your API request. Pricing information can be found here.
We will share another update once all Toll-Free numbers are generally available for sending and receiving MMS messages from recipients in US and Canada.
