For HTTP V1 and V2 API customers, external media means you include a URL, and we will fetch the content. Stored media means you upload the content to the Bandwidth Application Platform media server. You can find out more information in our V1 and V2 developer docs. For MM4 customers, you provide the content itself in the message payload. 

Important: Message size does not equal media size. Message size includes all the pieces of the message: the text, the media, headers, etc. Due to differences in handsets, file types, and transcoding, we recommend you only send attachments that are no larger than 500KB to ensure the best chance of delivery.
