Dumb question. Which symbol is which?

[Norwood]

So, I have my device set to switch to my work and home Wi-Fi networks automatically.

When they connect, which icon at the top am I looking at for signal strength? Is it this symbol or this one?

Because both of them are moving.

The vertically stacked arcs is your wifi strength while the horizontal bars is your cell signal strength (for those odd moments when you actually want to use your phone as a phone or for sending an SMS over the actual cellular network).

This thing makes calls?

Thanks.
