Right, you have to make sure it's set for end-to-end encryption, which isn't obvious and can be undermined by features like "chat backups" etc.
Signal is better for secure communications.
That said, I wouldn't have any qualms about giving mine over the phone (assuming I knew who I was giving it to). Unless you have a reason to suspect you (or the person you're talking to) are being specifically targeted, it's almost inconceivable someone is listening in on your phone calls.
