# MMS Limitations

- The maximum size for attachments is 3MB.

- It is recommended that only one attachment be sent at a time to avoid going over the carrier's size limit.

- ConnecttoTeams will support whatever file types your carrier supports. Refer to your carrier's documentation to confirm supported file types.

- File names may be changed by the carrier in transit. Do not be alarmed if the file name appears as a hash by the time it reaches the recipient.

- MMS attachments will be retained on the ConnecttoTeams server for one month.

- Twilio sometimes sends attachments as a hyperlink within an SMS message.
