We support sending and receiving picture messages between Twilio US short codes and major US carriers (AT&T, Verizon, T-Mobile, Sprint). The majority of our short codes also support MMS over US Cellular, but there are a small subset of short codes that do not.
Customers applying for a new short code can indicate that they want MMS on the application; existing short code customers can have MMS added to their short code by contacting their account manager. Adding MMS to a short code costs a one-time fee of $500.
Short code provisioning can vary considerably depending primarily on the time that it takes for mobile carriers to review and approve your short code. On average, short code provisioning takes 8-12 weeks from the time that you make your initial payment to when the short code is live on major carriers, but in some cases can take longer.
UK and Canada short codes do not currently support picture messaging.
