How can foreigners at the airport make a call to Chengdu Hotel for their free pick up?

Hi, as I konw, you can easily find the car phone in the airport, but you need buy a card in convenient shop there to make it work well.
Or you can use the phone of the supermarket in the terminal to call your hotel. Also the information desk may provide you with a telephone.
One more suggestion, you can reserve the free pick up bus of your hotel in advance in the internet and tell them your specific landing time so that they can give you the right and timely service.
