If a phone is connected to another device through WiFi direct, will that connection prevent the phone from using cellular data?
Edit:
An iPhone is connected to a dash cam using WiFi Direct (the dash cam shows as a WiFi network when turned on and the iPhone connects with the dash cam by joining the network and putting in the password).
I've read somewhere that iOS can't connect to both WiFi and cellular data at the same time. I just wanted to know if using WiFi directs prevents an iOS device from utilizing cellular data.
