On a call from an associate, turns out she was calling me on the 240 area code number, which comes over the Internet. When she called me on my cell phone my tablet never made a peep.

Yeah it is kind of neat. I usually answer my calls on the Apple MacBook Pro while working so I don’t have to fumble the phone around. I’d feel weird talking to the iPad mini so I didn’t allow the feature on it.

Both iOS and Android support WiFi calls (routing calls over WiFi instead of cellular).

I have MagicApp, the android app that allows me to !make and receive calls on my Android tablet on ,240-345-6675 just as if it was a real telephon. This tablet has two sim card slots, meaning it can handle cell phone calls. It does not have any sim cards installed.

The weird thing is, every time my 703 area code cell phone rings, it also rings on !y tablet, but it's not the cell phone app that is picking up, its MagicApp! The only thing I can figure is maybe TracFone Is cheating, and is using WiFi to deliver the call. But that doesn't make much sense either; each device on Wi-Fi has its own IP address. I'll have to try an experiment where I have someone else with a cell phone come into my room and call it, and see if I connect to them.
