Why has it be connected to Wi-Fi?
Should be working under the mobile data mode instead of can only be used with Wi-Fi connection.
Auto connect always not work and must need Wifi
After the app launch so many years. The auto connect function still always not work due to the app will hang or quit itself after inactivity for a while.
Moreover, when you travel and buy the day pass, you want necessarily connect to WiFi anymore, meaning that cannot use this app for voice call if have data roaming which is no use at all. Suggest King King should not limited to WiFi but 4G as well when in roaming status.
Worst experience so far
For calling app, the experience from KingKing is the worst so far. Every time when I make a phone call, if the screen gets dark due to auto energy save, the phone call disconnected at once. So when I want to make a phone call overseas, I need to set the screen to “on forever” mode and watch very carefully that nothing covers the light sensor to prevent the screen gets dark. Having done so, have of my phone call got disconnect regardless.
