What is the difference between SMS and MMS Messaging?

SMS stands for Short Message Service and is the most widely used type of text messaging. With a SMS, you can send a message of up to 160 characters to another device. Longer messages are normally split up into multiple messages.

MMS stands for Multimedia Messaging Service. With a MMS, you can send a message including pictures, video or audio content to another device.

Helix Telecom supports both SMS and MMS on the Helix text message website at https://text.phone123.me.
