Make sure you always have internet access in China with a portable WiFi router that will work anywhere in the country. Keep up to 5 of your mobile devices online at once by connecting to China Mobile’s 4G network. You can enjoy 4G LTE speeds for up to 500MB per day, and then unlimited 2G speeds afterwards, more than enough for messaging, maps, and general internet surfing. You can pick up your portable WiFi egg right after landing at Xi'an Xianyang International Airport (XIY). Simply show your voucher at the counter, complete the registration process by taking a picture with your passport and WiFi device, and pay the security deposit. After that, you’ll be able to connect to the internet anywhere you travel within Mainland China. When you are ready to go home, simply return the device at the airport before checking in for your flight. Make sure you don’t return the device late or you will forfeit your deposit!
