How do I add Game Center friends?

UPDATE: since the release of iOS 10 this response no longer applies. Hopefully Firemonkey will find another way besides Facebook for iPhone/iPad users to add friends.

Here is how to add friends to Game Center (GC):

Open your GC and tap on friends.

At the top left area you will see a + sign. Tap on that. (See first screenshot below)

A message window will open (see second screenshot below). Type the person's GC ID in the To: section. Then type a message to let that person know why you are sending them a friend request. Something like "need sims Freeplay neighbors" or "Play sims Freeplay" would be appropriate.

You will not get any confirmation that they received the message unless they accept your request.

I also added a screenshot of the request I sent you.

Thanks,

Now, however, now that I have a new friend in GC, how do I get that friend to be a neighbor in the Sims game platform? When I go to the party boat, it only has Facebook as the medium to add friends.

@sebush1912

You needt to log into GC through sims Freeplay just like you did for Facebook.

Mine doesn't have the Game Center listed under Facebook anymore. Is there a way I can put it back?

All of my neighbors are from Game Center, so now I have none. ):

Are you still using an apple product? iPhone/iPad? Then you may need to reboot your device and/or restart the game app.

Sorry but where I can find the Game Center and where I can find my ID? I have logged with Facebook and Google.

Thanks

Game Center is only on Apple products. Since you're logging into google I'll hazard a guess that your device is not an apple product.

Thanks for the explanation @martha4858!
Now I have undestood why I can't know this "Game Center". So, with Android, the only way to add a friends is with Facebook?

@AngelSara357

I am not sure. You said you logged in to google through the game? If so you should be able to add friends that way. If I find anymore info I'll post it.

These login options do not show up for the windows phone version! We have no way of adding friends!
