About 90 percent of Chinese travelers consider Wi-Fi indispensable when traveling abroad They often use phone apps to create travel routes and book hotels, which requires large data flows that can be expensive without Wi-Fi

　　But free Wi-Fi is not always available, even in regions with advanced telecnrnmunications，such as the United States and Europe. Portable Wi-Fi costs 15 -50 yuan a day，depending on the country. Ifs cheaper in South Korea,Japan and Thailand. The Wi-Fi services increase rapidly thanks to reasonable pricing and smooth surfing

A travel website Ctrip leases Wi-Fi transmitters that offer unlimited data for about 20 yuan a day on average in more than 100 countries. It plans to make mobile Wi-Fi an important part of its business model. Another travel website Tumiu also launched a Wi-Fi phone service in 2017. More than 100, 000 people used the service in 2017.

　　More than 100 million Chinese went abroad last year, and the 10 percent who used Wi-Fi services spent an average of 150 youn, and it’s expected to grow largely. But the business may become out of date in five to eight years, for more locations am offering free Wi-Fi. 1n the meantime, it is reported that more for-profit models should be introduced and offer more services for outbound travelers in the future
