Does a factory unlocked iPhone need a sim card when setting it up?

I know alot of iPhones require a sim card for you to go to the next step of setting it up. If it's factory unlocked would I need a sim card…

All iPhones need a SIM when setting them up.

  • Why Iphone 4S won't read T-mobile Sim card even though factory unlocked? I have an iphone 4S and it reads Att sim card no problem, i had the phone factory unlocked and it even said Congratulations your iPhone is unlocked after i restored it in iTunes, but all it says is no service i tried two different T-Mobile sim cards. I even checked my imei number online and it said the phone was factory unlocked. Is there anything i can try, i've never ran across something like this.

  • My factory unlocked iphone 4s doesn't recognize my sim card? I purchased a used 32GB factory unlocked iPhone 4S on ebay and it will not activate with my t-mobile sim card no matter what I try either on the phone or in itunes. I'm pretty sure the phone is unlocked because I looked up the IMEI number online and it said the phone was unlocked. I did trim the sim card myself so it could fit in the iphone but it still works in my old phone still so I know i didn't damage the sim card. Any help on how to resolve this would be appreciated!
  • Locked iPhone and need sim card to use because I restarted it but i don't have the specific sim I need. Please i'm desperate? Ok so my aunt got me an iPhone from Canada but its sim locked and it says I need to insert a sim card for it to work. The problem is i don't have a sim from that specific company that locked it and the only thing I can do is emergency calls and all that. I can't even use it as an iTouch or something.
