Frequently asked questions
Our MMS API supports a wide range of media formats including JPEG, PNG, and GIF images, as well as MP4 video and MP3 audio files. For optimal delivery across all carriers, we recommend keeping file sizes under 600KB. Larger files may be compressed automatically or rejected by certain carriers depending on their individual limits.
MMS messaging is currently supported in the United States and Canada across all major carriers including AT&T, Verizon, and T-Mobile. MMS is available on 10DLC numbers, toll-free numbers, and short codes. If a recipient's carrier doesn't support MMS, the message can be automatically converted to an SMS with a link to the media content.
Sending an MMS message is as simple as making a single API call. Include the recipient's phone number, your MMS-enabled sender number, and a publicly accessible URL for the media you want to send. Our API handles the rest — including carrier negotiation, media optimization, and delivery confirmation via webhooks. Check out our developer documentation for code examples in Python, Node.js, Java, and more.
An MMS (Multimedia Messaging Service) API allows you to send messages that include rich media — images, GIFs, video, and audio — alongside text. Unlike SMS, which is limited to 160 text characters, MMS messages can include media attachments up to 600KB and longer text content. MMS messages tend to drive higher engagement because visual content captures attention more effectively than plain text.
Swift SMS Gateway offers a simple, reliable MMS API with direct carrier connections across the US and Canada. Our platform handles media optimization, carrier negotiation, and delivery confirmation automatically so you can focus on your content. You get detailed delivery receipts, webhook support, and the same developer-friendly REST API used for SMS.
If a recipient's device or carrier doesn't support MMS, the message can be automatically converted to an SMS with a link to the media content. This fallback ensures your message still reaches the recipient regardless of their device capabilities.
Yes. The Swift SMS Gateway MMS API provides delivery receipts via webhooks, so you can track whether each message was successfully delivered to the carrier and handset. You can use this data to monitor campaign performance, troubleshoot delivery issues, and maintain accurate messaging logs.
