MMS and the media a page will store
The forty-second video line is the encyclopedia's description of MMS, not a promise from every carrier. Bandwidth's numbers are narrower and more useful for that API: 3.75 MB, 48 hours, segment count 1 for MMS, and no stored message text.

- Wikipedia says MMS sends multimedia content to and from a mobile phone and extends SMS so messages can be longer than 160 characters.
- The article says MMS can deliver up to forty seconds of video, one image, a slideshow, or audio.
- Bandwidth's messaging guide says the API sends SMS and MMS over HTTP, and that an MMS segment count is always 1.
- The same guide says you can upload files up to 3.75 MB, storage is described as free, and files are stored for up to 48 hours.
- It also says Bandwidth does not store text message content after the webhook is delivered, only metadata.

What is going on
The forty-second video line is the encyclopedia's description of MMS, not a promise from every carrier. Bandwidth's numbers are narrower and more useful for that API: 3.75 MB, 48 hours, segment count 1 for MMS, and no stored message text.
Privacy is a design fact on that page. If your app needs the body later, you keep it yourself. The platform page says it does not. Do not put a customer's message into this study lab either.
Worked example
A photo reminder: write MMS, then 3.75 MB and 48 hours if the provider is Bandwidth. Write confirm if the provider is someone else. The forty-second figure stays in the Wikipedia column.
Quiz
1. Bandwidth's guide sets the MMS segment count to 1.
True. That sentence is on the messaging page.
2. Bandwidth's guide says it keeps the text of the message for you to download later.
False. It says content is not stored, only metadata, once the webhook is acknowledged.
Ecosystem
Sister pieces sit on the ecosystem page: the glossary, the mind map, the integration map, and the bridges.
- MMS — The multimedia message Wikipedia describes as an extension of SMS.
- segmentCount — The field Bandwidth says it returns. For MMS the guide says the value is always 1.
Config. Record the size limit and the retention only for the vendor whose page you copied.
Troubleshooting. A missing image after two days matches the 48-hour storage sentence. Fetch it before you call the carrier.
Bridge. SMS is the 160-character article. MMS is this room. A provider that accepts both still wants the channel named.
Mind map, sister technologies, and future hooks live on the ecosystem page.
