Multimedia Messaging Service (MMS) enhances text marketing by allowing businesses to send images, GIFs, and short videos. It seems like an excellent way to engage customers, but adding sound to MMS? That’s a serious mistake.
Marketers are always looking for ways to make their messaging more engaging and interactive. However, MMS with sound creates more problems than benefits. It results in poor user experience, delivery issues, and wasted marketing budgets.
Before you launch an MMS campaign with sound, let’s break down the major reasons why this approach is flawed—and explore better alternatives that ensure engagement and higher conversions.
Not All Devices Support Sound in MMS
Unlike traditional SMS, MMS delivery is inconsistent across different carriers and devices. While modern smartphones support video playback, not all of them properly handle MMS with sound.
Common Issues with Sound in MMS
- The sound fails to play automatically
- The audio is out of sync with the video
- Some devices strip out the sound completely
Even if a user receives the MMS, they may not hear the intended audio, making your carefully crafted message ineffective. You don’t want to send a video only for the sound to be missing.
Older Phones and MMS Limitations
Not everyone uses the latest smartphones. Many older devices struggle with MMS playback, leading to:
- Blank or black screens instead of a video
- Error messages saying the content can’t be played
- Distorted audio that makes the message incomprehensible
If even a small portion of your audience can’t hear your message, your campaign is already losing impact.
Autoplay Issues Create a Bad User Experience
When users scroll social media, videos autoplay silently with captions, allowing people to engage without disrupting their environment. But MMS doesn’t work like that.
What Happens When You Send an MMS with Sound?
- The user opens your MMS in a quiet office or public setting.
- The video doesn’t play automatically, so they assume it’s broken.
- If they tap to play, sudden loud sound annoys them or catches them off guard.
Now, instead of engaging, they close the message out of frustration.
Good marketing should be frictionless.
If users need to take extra steps just to hear your message, they won’t.
With most MMS platforms lacking autoplay options, your message relies on users manually enabling sound, which lowers engagement rates significantly.
File Size Limits Lead to Poor Video and Audio Quality
MMS messages have strict file size limits set by carriers. Most cap MMS file sizes at 300-600 KB, which is tiny by today’s standards.
When You Add Sound to an MMS
- The video must be heavily compressed, reducing quality
- The audio becomes distorted or muffled
- The message may fail to send entirely due to file size restrictions
Even if the video and sound make it through, the low-quality playback ruins the experience. Instead of looking professional, your message appears blurry, pixelated, or poorly edited—damaging your brand reputation.
Users expect high-quality video and crisp sound. MMS simply can’t deliver that.
Delivery Failures Are Common
Unlike SMS, which delivers reliably across all devices, MMS is inconsistent. When you add video and sound, the risk of delivery failure increases significantly.
Why MMS Fails Frequently
- Some carriers block large MMS files
- Older phones can’t process MMS properly
- Users on Wi-Fi-only networks may not receive MMS messages
- Certain mobile plans disable MMS to save data
Even when an MMS technically delivers, it might arrive as a broken or unreadable file, making your marketing efforts pointless.
If your message doesn’t reach the customer, it doesn’t matter how good your content is.
Many Users Have MMS Disabled
Not all users enable MMS on their phones. Some turn it off to save mobile data, while others use third-party messaging apps like WhatsApp or Telegram, which don’t support MMS.
Why This Matters for Your Campaign
- A large percentage of your audience never sees your message
- Your marketing budget is wasted on failed deliveries
- You miss valuable engagement opportunities
Instead of relying on an unpredictable messaging format, it’s smarter to use a method that guarantees high delivery rates and engagement.
SMS + Link Previews Work Better for Engagement
Rather than sending MMS with sound, use a more reliable alternative that ensures higher engagement, better quality, and improved delivery rates.
A Better Approach
- Send an SMS with a clickable link to a high-quality video hosted online
- The recipient can watch the video at full resolution
- Sound will play properly, and the experience will be seamless

Why This Works Better Than MMS
No file size limits—ensures crystal-clear video and sound
High delivery rates—SMS reaches all users, even those with MMS disabled
Better user experience—users watch the video when and where it’s convenient
Instead of hoping your MMS delivers correctly, you control the customer journey by directing them to a reliable video experience.
Final Thoughts
MMS with sound might seem innovative, but it creates too many issues:
Incompatible devices and playback failures
Poor user experience due to manual sound activation
Severe compression and quality loss
High failure rates across carriers and networks
Instead, use SMS with link previews to deliver high-quality, engaging content without the risks of MMS failures.
