My e6 package. The text message tells us that there are still 10 hours of no use W 1F 1. What is w 1f 1?

Wi-Fi is a short-distance wireless transmission technology, a wireless network protocol, which can support radio signals of Internet access within hundreds of feet, and it provides users with wireless broadband Internet access. The location where the Wi-Fi network is accessed is called a hotspot, and users can enjoy high-speed Internet access service at the lowest 1M and the highest 54M in the hotspot coverage area.
