Can I unlock my iphone 5s using someone elses nano sim ?

[Anonymous]

Finally got the text from O2 telling me I can finish unlocking my iphone 5s by putting in a non-O2 sim card and connecting to iTunes. I don't have any nano sim cards but I know someone with an iphone 6. Can I put their sim card into my iphone and finish the unlock process ?  Or will that delete all their data or match up their account data with my old phone ?   If I can't use someone else's sim card, do I have to buy a new nano sim?

All very confusing. Would appreciate some help from anyone who has done something similar.

To be honest you are much better just getting another network SIM from a supermarket for 99p our get free ones online for any of the networks.

Any non o2 sim will be fine (do not use giffgaff, tesco as they are o2) and nothing will sync from the sim card as long as you are signed into iTunes with your own Apple ID.

Ok thanks, I'm going to buy a cheap PAYG nano sim (EE).

So that should finish unlocking my iphone. Now what happens when I want to use my iphone with another SIM card (I'm giving my phone to someone else). When they put their SIM into my iphone, will it work (can they just set it up as new?) or do I have to go thru the same process again with iTunes and my laptop ?

They just put their own son I the phone and set it up as new unless they already have an iPhone in which case they just set it up from a previous back up. All done via iTunes.

They could also restore it from an iCloud back up if they have one but your old phone and their old phone would need to be on the same firmware version.
Make sure you also reset yours before handing it over.

Just popped the PAYG SIM into my iPhone and connected to iTunes on my laptop.

After a few seconds I got the message "congratulations your iphone has been unlocked"

Is that it ?   I was expecting it to sync and restore settings etc.

No, that's it.
No need to do anything else.
