Signals travel both ways.
You can't allow signals to come in, (incoming call), and expect to block
signals from getting out (transmissions).

If you leave the phone on, it will occasionally transmit out, to ask the
tower if there are any messages, and to let the nearest tower know where
it is, so incoming calls can find it.
This is not consistent with a desire to shield the phone.

If you shield the phone, you can not expect incoming calls to work. It
would at best allow you to say you are carrying the phone according to
company policy, and yet keep it from working, (or affecting you.)
Best to turn the phone off, then it won't transmit or receive.
