Absolutely you can! At arrivals, you’ll be surrounded by a ton of services, and most of all, you’ll see little areas to activate phone cards. As you can well imagine, like everything else in airports, prices are higher than normal, but if you have no problems spending a few more RMB you can leave the airport with your brand new phone card and be ready to look for the best services and tourist itineraries China can offer. Obviously, prices will vary depending on which company you choose, your desired rate, and how long you’ll be staying in China.
