To this, Dunleavy replied that MAS was calling the mobile phones of the crew members as well, which were ringing, and that he had given the numbers to Chinese investigators.

Again the tone is not from the cell phone but from the controller.

On what do you base your knowledge.

Because there are reports that the cell phone WILL NOT ring unless a cell phone tower can pick up a connection.

Btw, taking the battery out is not enough of a test.

WOuldn’t you also have to take out the Sim card

It is not the ring that is odd. You are right that the controller determines whether the phone rings. What is odd is that the call is answered and hung-up. If the phone is disabled (i.e. in the water), the phone should roll-over to voicemail.
