Wi-Fi options for free FaceTime call from USA to Australia

Hi llcp12,

welcome to the Apple (user-to-user) Community!

Re: Wi-Fi options for free FaceTime call from USA to Australia

I know what you mean, yet you will still use some of your wi-fi data when making FaceTime calls using wi-fi.

Am no expert in this area, yet your request deserves some response.

Please see if the encouraging answer given by a "Community Specialist" in this discussion thread helps:

Re: I am uncomfortable because I am afraid of a large bill.

ie: I trust you will be calling from an Apple device to an Apple device, so all have access to FaceTime using wi-fi. (Else for Apple to Android or Windows, it could be best to send an internet link for them to use for FaceTime.)

If you wish: For peace of mind:

"You can turn cellular data and roaming on or off, set which apps and services use cellular data, see cellular data usage, and set other cellular data options".

See: View or change cellular data settings on iPhone - Apple Support

NB: You can turn off (or back on later) Wi-fi Assist, which, when on, uses cellular data if / when a wi-fi signal is inadequate: See: About Wi-Fi Assist - Apple Support

Re: "I have two options…”use Wi-Fi while roaming” or use Wi-Fi only on this phone”.

I do not know which one to turn on".

Sorry I don't know, as I haven't used those settings myself, and do not know your wi-fi set-up.

This third-party (non-Apple) Article suggests wi-fi while roaming assists when moving away from your modem / router and connecting to other nearby wi-fi access points. (ie: says: "You need to have multiple access points throughout the building" )–

All the best :-) 🇦🇺
