SMS and MMS

Sending an MMS or SMS

MMS messages can be sent in the US and Canada using Twilio. In other countries, the message is sent as an SMS with a link to the photo. The image link in an SMS is valid for 7 days.

To use this service, create a Twilio account and enter your account details in the MMS settings dialog. Twilio charges per message — see their website for pricing.

When the user taps the MMS icon in the sharing screen, a touchscreen keyboard appears for entering their phone number.

MMS Settings

Open the MMS Settings dialog by clicking SMS/MMS settings… in the Output Settings dialog.

Enter your Twilio message phone number, AccountSID, and AuthToken. Set the country prefix (e.g. +1 for US/Canada, +44 for UK). Users can enter their number with or without the prefix.

Message Types

Photos sent via MMS or SMS + image must be no larger than 1 MB after resizing and cropping.

Image Sizing and Cropping

You can crop, resize and rotate photos before sending. The image is cropped first, then resized, then rotated. Use Max width and Max height to limit file size. GIFs and MP4 files are sent without resizing or cropping.

Select Use MP4 copy of animated GIF if available to send the MP4 version.

From v3.16, texts are sent in the background. When the user enters their phone number, an XML copy of the message is saved and queued for background sending.

Payment Mode

Select Payment mode to require payment before sending. When the user enters a valid phone number, the mms_payment.jpg screen is displayed until payment is accepted, cancelled, or a timeout occurs.

Custom screen images:

• mms.jpg — displayed while sending
• mms_success.jpg — displayed after successful send
• mms_as_sms.jpg — displayed when MMS falls back to SMS
• mms_error.jpg — displayed on error

Offline Mode

If no internet connection is available, enable MMS/SMS Offline mode in Output Settings. Send queued texts later via File -> Send emails and MMS/SMS messages…

See Email for details on the offline sending workflow.
