Symptoms

You may notice of the following:

​
When sending MMS

  • “Add photos” button within Messages is greyed out
  • Images fail to upload or send
  • Only text delivers, without attached images
  • Sending works on one number but not another
  • Sending works in one direction but not another

​
When receiving MMS

  • You receive the text but not the image
  • MMS appears as “missing media”
  • Images show as broken files
  • MMS never arrives
  • MMS arrives only when sent from certain numbers

​
How MMS Works in CloudTalk

MMS is more restricted than SMS. To send or receive MMS, all of the following must be true:

​
MMS requirements

  • Both the sender and recipient numbers must support MMS
  • The number must be a US or Canadian number (MMS currently works only in these countries)
  • MMS must be enabled for your CloudTalk account (available by request)
  • The number must support media messaging
  • Your account must have active credit (trials or accounts with no credit cannot send MMS or SMS)

​
MMS size limits

  • Up to 10 images per message
  • Total MMS size up to 5 MB
  • Supported file types: .jpg, .jpeg, .png, .gif
If any of these conditions aren’t met, the MMS option will be unavailable or the message will fail.

​
Root Causes

​
⚠️ Your number does not support MMS

MMS is currently supported only for US and Canadian numbers, and only when enabled for your account. MMS will not work if:
  • The number is outside the US or Canada
  • MMS is not activated for your organisation
  • The number type does not support media messaging
When MMS is not supported:
  • The MMS icon is greyed out
  • A warning flag appears above the message composer
  • Switching to another (unsupported) number disables MMS immediately

​
⚠️ Your account has no credit

If a trial or paid account runs out of credit:
  • MMS is blocked
  • SMS is also blocked
  • A warning flag appears in the app
Top up credit to restore MMS functionality.

​
⚠️ MMS exceeds size or media limits

MMS will fail if:
  • More than 10 images are attached
  • Total media size exceeds 5 MB
  • File types are unsupported (.webp, videos, PDFs, etc.)
Try reducing the number or size of images before resending.

​
⚠️ Destination number does not support MMS

Even if your CloudTalk number supports MMS, the recipient number may not. Examples:
  • Landline numbers
  • VoIP numbers without MMS
  • Mobile carriers that support SMS but not MMS
  • Numbers outside US/Canada
If MMS works with some recipients but not others, this is the likely cause.

​
⚠️ Media formatting or device limitations

Some carriers compress, convert, or block media. Issues may include:
  • Images arriving pixelated
  • GIFs not animating
  • Certain file types not displaying
  • Multiple images being grouped or separated
This depends on the destination carrier and cannot always be controlled.

​
⚠️ App or device caching

Occasionally images fail to preview or load because of:
  • Slow mobile data
  • Unstable Wi-Fi
  • App caching issues
Refreshing the conversation or reopening the app often fixes it.

​
Step-by-Step Troubleshooting

​
  1. Confirm that MMS is supported for the number

In CloudTalk Phone (Desktop or Mobile):
  • Open the conversation
  • Look for the image icon
  • If the icon is greyed out, MMS is not supported for the selected number
Try switching to another US or CA number that supports MMS. If you don’t have one, contact Support to request MMS activation.

​
  1. Check your account credit

If your account is on a trial or has run out of credit:
  • MMS and SMS will be blocked
  • A warning flag will appear
Add credit or upgrade to restore messaging.

​
  1. Test sending MMS to multiple numbers

Test with:
  • Your own mobile
  • A different US or Canadian number
  • A colleague’s number
If MMS works only in some cases, the issue is likely with the recipient’s carrier capabilities.

​
  1. Reduce the size or number of images

If the MMS fails to send:
  • Remove large images
  • Reduce the number of attachments
  • Compress the files
  • Keep total size below 5 MB
Try sending one image first, then add more.

​
  1. Check file type compatibility

Make sure all attachments are:
  • .jpg / .jpeg
  • .png
  • .gif
Other formats will not send.

​
  1. Refresh the app or messaging thread

If the MMS appears missing or broken:
  • Close and reopen CloudTalk Phone
  • Switch between numbers
  • Refresh or reopen the conversation
  • On mobile, toggle Wi-Fi / data
This helps reload cached media previews.

​
  1. Switch to SMS temporarily

If MMS fails repeatedly, try sending a standard SMS to confirm messaging is working normally.
