With the widespread use of smart phones, people have become increasingly inseparable from the mobile phone network. However, mobile phone traffic charges are not cheap, and limited traffic often makes mobile Internet access stretched. At this time, people are most expecting wifi. People always habitually connect to WiFi no matter where they go, but the problem is coming again. WiFi Internet access also requires a password, so I often encounter the embarrassing situation that there is no password for WiFi and can't get online. The following small series teaches you to use the Wifi connection app for Free " Wireless & rdquo; for free on WiFi. Some news said that "Crystal Wireless" is using China Mobile's WiFi management vulnerability to provide users with free wireless Internet access. Moreover, it is said that in the later version, users can easily connect to the WiFi network of China Telecom and China Unicom. We all know that many Wifi hotspots are difficult to be discovered by users, and the login process is cumbersome. Therefore, the current WLAN user experience is generally poor, which provides a living space for such applications. At present, in the major mainstream Android market, you can download this free application. To use the wireless wireless, you must first turn on the mobile phone Wifi and use the wireless wireless. Users can skip the “verification interface for WLAN user login” set by the carrier, and use the operator's WiFi hotspot directly without entering the user name or password, and all fees are waived. Of course, Chang Wireless will prefer public Wifi, but if you have an internal Wifi in your location (such as an office), I recommend using internal Wifi. After all, public Wifi is not as fast. Changdou: Encourage users to download software and wirelessly set their own currency unit ——& quoquo;Changdou”. With Changdou, you can break through the single time limit and avoid advertising. If the user downloads the software according to the prompt of the wireless, then you can get Changdou. To get the smooth beans to motivate users to download the recommended software, this may be the profitable point of the wireless. LBS function: Viewing nearby hotspots can not only allow users to connect to the operator's WiFi hotspot conveniently and quickly, but also quickly view the user's own location and find all hotspot information within tens of meters to two kilometers. . Chang Wireless currently supports: China Mobile CMCC (excluding Shandong, Guangdong, and Jiangxi) and China Mobile CMCC-EDU's Wifi network in several universities in Shanghai. It is said that in later versions, it will also support Wifi in commercial venues such as “One Tea One Sit &”, “Starbucks”. Some people have analyzed that Chang Wireless should have a large number of WLAN electronic card accounts built in for free. The company has purchased a large number of WLAN electronic cards. The purpose may be to attract users to download software, expand the influence of software, and charge fees through software built-in advertising. But for the user, it does break the Wifi account password limit, which is a very useful feature. So interested users can install one on their Android phone.
