What fits into 1 MB
1 MB is about 20–30 seconds of small (240p–360p) video with sound. The preset lowers the resolution automatically to keep the picture readable. If your clip is longer, trim it first or send a link instead.
Carrier limits (approximate)
- AT&T, T-Mobile: about 1 MB to send
- Verizon: up to about 1.7–3.5 MB
- Other networks usually follow their host network
The recipient’s carrier can also reject or shrink large messages, so 1 MB is the safe choice.
Questions
Why does my phone say the video is too large to send?
MMS has strict size limits set by the carrier — often just 1 MB. Compress the video below that first.
Does iMessage have the same limit?
No — iMessage and RCS chats allow much larger files. The MMS limit applies to plain text messages.
