Kixie Users can send MMS from the My SMS (Direct Phone Number) or Team SMS (Group Phone Number) SMS fields in PowerCall.

Choosing an SMS Field to Send From

When using PowerCall to send an MMS, you can send from your Direct Phone Number or a Team Phone Number:

  • My SMS (Direct Phone Number): This is your personal sending option. When you choose this, the recipient will see the message coming from your unique direct number.

  • Team SMS (Group Phone Number): Opt for this when you're communicating as a team. MMS sent from this field will appear to the recipient as coming from the collective group number.

Supported File Types for MMS

PowerCall supports the following file formats for MMS:

  • PDF
  • JPEG
  • PNG
  • GIF

Attachment Requirements

Keep the following limits in mind when attaching files to your MMS:

  • Attach up to 10 individual files in a single MMS.
  • Ensure the total combined size of the attached file(s) does not exceed 4.6MB.
  • Ensure that the individual size of any one attached file does not exceed 0.675MB if sending to AT&T or Verizon, 1.4 MB if sending to Sprint, or 1.5 MB if sending to T-Mobile.

Attaching Files to Your MMS

There are two methods to add your files:

  • Drag and Drop: Simply drag your desired file(s) and drop them into the PowerCall interface.

Once you've attached the files, you'll notice thumbnail previews in the message field. This provides you a quick overview of your attachments, and these previews will also be displayed in the ongoing SMS thread.
