How do you check your messages while on a phone call?

To check your messages while on a phone call, you can use the "hold" feature to put the call on hold and access your messages, or you can use a second device to check your messages simultaneously. If your phone supports it, you can also use a split-screen feature or multitasking mode to view messages without ending the call. Just be mindful that some networks may not allow this, and the person on the other line might not be able to hear you while you're accessing your messages.
