Voizee enables businesses to communicate effectively through SMS and MMS campaigns, helping organizations reach their audience with text-based and multimedia messages. Below, we’ll break down the differences between SMS and MMS, when to use each, and how to send campaigns from Voizee.


What is the Difference Between SMS and MMS?

Both SMS (Short Message Service) and MMS (Multimedia Messaging Service) are widely used for mobile communication, but they serve different purposes:

  • SMS: A text-only messaging service limited to 160 characters per message. It is ideal for quick updates, reminders, and transactional messages.
  • MMS: Supports longer messages (up to 1,600 characters) and allows images, GIFs, videos, and audio files. This format is best suited for marketing campaigns, event promotions, and engaging multimedia communication.

Credit Usage for SMS vs. MMS

Message Type Character Limit Media Support Credit Cost
SMS 160 characters ❌ No 1 Credit
MMS 1,600 characters βœ… Yes (Images, Videos, GIFs, Audio) 2 Credits

πŸ’‘ Tip: For longer messages, sending an MMS is often more economical than multiple SMS messagesβ€”even if no image is included.


When to Use SMS vs. MMS?

βœ” Use SMS for:

  • Quick reminders, confirmations, and alerts
  • Simple text-based announcements
  • Messages that do not require multimedia elements

πŸ“’ Use MMS for:

  • Promotional campaigns (sales, offers, discounts)
  • Visually engaging messages with images or GIFs
  • Event invitations with media attachments
  • Text messages exceeding 160 characters (to save credits)

Best Practices for MMS Image Formatting

  • πŸ“ Aspect Ratio: 9:16 (Portrait mode)
  • πŸ“Έ Resolution: 640px wide Γ— 1,138px tall
  • πŸ“‚ File Size: Under 500KB to prevent delivery issues
  • πŸ“„ Format: JPEG for maximum compatibility

βœ… Why Proper Image Formatting Matters?
