Does wireshark work if my cell phone has wifi turned off?
My husband is using wireshark to monitor my messages I send on my iPhone. If I turn off wifi can he still see what I'm doing and how big the packets are?

Okay I do have a SIM card... how can he use wireshark over cellular... and how can I stop it? If I'm not connected to the wifi network he shouldn't be able to capture anything... otherwise anyone could capture anything from anyone
This is why we use strong encryption... Hopefully your WiFi is protected with some variant of WPA2. If you are REALLY paranoid, you then use a VPN tunnel on top of WPA2, and run something like https or some other TLS encrypted traffic inside the tunnel.
This is a bit dated, but discusses your cellular question:
