Please tell me how I can talk to someone from my Apple phone to my Apple tablet on FaceTime

Hi JuneAshcraft,

Welcome to the Apple (user-to-user) Community.

Now I'm no expert in this area, yet your question surely deserves a response.

So here's my thoughts on the situation:

Seems you would need to create an Apple ID account for your sister.

Apple Support Article: Help your family member create an Apple ID,

(You might want to set up Family Sharing ?)

Make sure that each family member has a unique Apple ID - Apple Support

List your sister in "Contacts" on both iPhone and iPad.

Ensure you are also listed in "Contacts" on the iPad

Then help sign her in to FaceTime on the iPad with her own Apple ID.

With wi-fi:

You would be able to FaceTime her using the eMail address in her Apple ID account.

(If you wanted to use cellular, she would need a phone number to use in FaceTime.)

For accuracy:

Please choose the correct iPad OS version at the top in the article(s) below

Set up FaceTime on iPad – Apple Support

Make and receive FaceTime calls on iPad – Apple Support

If you wish:

Use SharePlay to watch, listen, and play together in FaceTime on iPad – Apple Support

What to do:

If you can't make or receive a FaceTime call on your iPhone or iPad - Apple Support

Possibly others with more expertise may join this discussion, once under-way.

(Sorry I am not fully confident ... ie: am unable to test this out properly.)

Failing that:

You may be able to set up something like the above, and test it out at home,

before you try it with your sister.

Please feel free to reply here, if you wish, or have questions.

All the best :-)
