What information will it ask for the preorder? This is my first time preordering a phone

I'm going to preorder the iPhone x, the carrier I'm going to select on the Apple Store app will be T-Mobile, I just want to know if it will ask me my wireless number, or my social security number, I know Verizon, Sprint, and AT&T ask information.

You could do a trial run of sorts using an iPhone 8/8 Plus, etc now. Its the same info being asked. Of course don't confirm any order while doing it.

  • My ask.fm won't let me ask anonymous? I have an iPhone 4, and I didn't update to iOS7. When the ask.fm app had an update recently, it didn't allow people to ask anonymous. So people could delete it then just not update it when they redownloaded it. Well I have deleted it like 3 times and I haven't updated it either. Why can't I ask anonymous questions still? And how can I?
  • Is tbere any major différence between thé iPhone 6 and the 6s? Whooppeee is Xmas again and my daughter wants new 2nd hand) iPhone… 2 years ago almost bought her 5 before i réaliséd that it was 5s she wanted ( cos thé 5 sucks?) And I don't want to screw up this year…
  • If I ask my cousin in Australia if she has a iPhone, should I ask for her Email address? My cousin Britteny lives in Australia and she has a 19 hour different time zone from us Californians. We text each other through my dads Facebook Messenger. If I ask her for her Email address and if she has a iPhone, do you think it will be a good idea to actually talk to each other? She is a 15 year old girl, and I'm a 14 year old guy.
  • I'm thinking about preordering the iPhone X? This is going to be my first time preordering an iPhone, I've been checking videos on how to pre order fast. But what I don't get is, what does it mean Store pick unavailable? Does that mean that they're out of stock?
