When placing the call he hears the following error message: "The number you have dialed is not in service." He tried to call our customer service number by dialing 905 272 5665, what is he doing wrong?Lu's view of the sky is obstructed.Lu is not registered to the network.The SIM card needs to be inserted.Lu cannot dial Canadian numbers with an American satellite phone.Lu should be dialing +1 905 272 5665.10.
