What is a data event?

[Teets1974]

There are phone calls going to unfamiliar numbers in my usage and it says it's a data event.

If the "data event" consumed 0.000KB of data in Self-Serve then it's an MMS attachment. They're "unlimited" (free) at Public Mobile, even though they're sent across a data connection.

There are other types of "data events" - different SMS and EMS protocols which can be augmented across data - I've intercepted some with a custom messaging app - but I never saw them reported in my Self-Serve usage.

MMS texts use data at no charge.If you attach an image or group text it will be an MMS text message. Normal SMS texts don't use data.

Does it mention MMS over to the right?
