How to have my contacts back? (iPhone)?

My sister and I share the same Apple ID, earlier today, she was messing with her iCloud and unfortunatly all of my contacts were gone and were replaced by half of her's. Is there anything I can do to get them back? It is really urgent.

If you called any of them recently check far back in call history other then that no other way to get the contacts back.

I would get yourself a google account and then all you have to do whenever you get a new device is put your Gmail account on the phone and all your contacts will automatically come onto whatever device you are using.
I know this can't get your contacts back but at least when/if you do manage to get them back in the future this will never happen again as all your contacts will be sync will your Gmail account.

  • Whatsapp contacts - if they're onnm contacts am I on theirs? I have the phone number of an old friend stored on my iPhone and they also show on my whatsapp contact list… Does this mean that they still have my phone number stored in their phone and also have whatsapp installed on their phone? The chat thing says they haven't been seen since 28th sept? If they didn't have my number on their phone would they still show as one of my contacts on whatsapp?

  • My contacts keep changing into my parent's contacts? I'm using my Dad's old iPhone 4, so it has all of his data. I cleared out everything that was his but I hate the part where each time my parent's add a new contact to their phone, everything syncs over to my contacts, so I'm scrolling down my list and see a new person I don't know but my parents do. Is there a way to change this?
  • Lost all my contacts, messages, and pictures on my iPhone, can I get it back? I got a new iPhone for Christmas and haven't synced it at all with the iTunes on my computer until now. When I synced it, it asked if I wanted to restore the information from my iPod, or start it as a new iPhone. I thought the restore option would just carry over all my songs, but now I've lost all my contacts, messages, and pictures I had on my iPhone and it looks exactly like my iPod does. Is there any way to fix this?
