MMS stands for Multimedia Messaging Service. It was built using the same technology as SMS to allow SMS users to send multimedia content. Though most popularly used to send pictures, MMS can also be used to send audio, phone contacts, and video files. Remember that SuperPhone® is not iMessage or Whatsapp so you have to play by the rules of SMS delivery. This means small files. 300 KB is often mentioned as the largest size most carriers will reliably handle. You can use a site like photoresizer.com to resize your photos.

Before we go on, let's stop right here to give you some advice: just because you can doesn't mean you should. The best way to send any media that's not a small photo or gif image (under 400kb) using SuperPhone® is actually to send a link to YouTube or Instagram where your media is hosted. This way you can avoid any carrier restrictions on the size of your media and you can drive more views, likes and comments to your content. We've seen over and over that clients using this method have much higher success terms of delivery and engagement.  Also keep in mind that subscribers using iMessage will receive a preview of your link and be able to view your content without leaving the chat as long as you're saved as a contact in their phone.

SuperPhone™ uses an integration with FileStack to send media files via SMS.

a. Select a conversation from the message list
b. Look for the 'paper clip' icon at the bottom left of any message thread
c. Click the 'paper clip' icon and select a file (see photo below) to send

Please note that photos will be converted to MMS and all other files besides your SuperPhone® vCard or small voice notes will be sent as download links instead of files. ALL PHOTO/AUDIO ATTACHMENTS MUST BE UNDER 400KB to appear in the chat view.
