How much data does FaceTime use?

Well for me, I used facetime for an hour and 2 minutes, and it only used 42MB of data. So it depends on your usage, I also think it based on your cellular signal, so 4G would use a lot more data than 3G because its outputting more quality when video calling.

my iphone SE says it used 1GB for a 35 minute call. That is more than my wifi can provide. Does 1GB refer to bits or bytes? 1000 Mb = 125 MB so I am thinking this is the correct figure but its unclear from what ios says.

If you are using FaceTime Video calling over Wifi, it doesn't use any data.

Cheers,

Hello,

If you go to settings -> cellular -> and look at FaceTime you can view how much data FaceTime has use so far!

It refers to bytes. 1 giga byte.

Does your wifi have a download limit?

Facetime should work correctly with internet connections as low as 5Mbps. Megabits per second.
