what is the area code for mobile numbers in Qingdao, Shandong

My husband's Adelaide, South Australia number has +61 in front of it, followed by the 10 digits of the mobile phone number. He's given me a phone number for his new Chinese phone that starts with 1500 followed by 7 digits. Do I need any other numbers in front of that? I'm trying to set up WeChat with his new phone number. Thanks for any help you can give.
