new phone AND new sim

[zippy1]

I have a new phone and as it takes a nano sim the sim card from my old phone doesn't fit, and so I also have a new sim.

What nobody seems to be able to tell me (not even O2) is whether I put the new sim into the new phone BEFORE I turn it on for the first time and go through the new phone setup process and THEN do a sim swap, or is there some other way to do it ?

the new sim should be in the new handset and the sim swap initiated with the old handset and sim as it should send a code to the old sim / phone to prove ownership

thanks for the reply but that doesn't answer the question of whether I insert the new sim and switch on the new phone and go through its setup BEFORE I try to do the sim swap ?

It makes no differance as soon as the swap goes through your number will be associated with the new sim.

In the past I have started setup of new phone and then started the sim swap on old handset with no issue

@zippy1 I don't know what new phone you have, but if it's an Android phone you don't need a sim in the phone to set it up. All you need is a WiFi connection and your Gmail details. You need the sim inserted to set up the network APN, but the phone setup itself is a different issue. I'm not an Apple person, so I don't know if the same holds true for iPhones.

Any phone can be set up with or without a sim in it.
Just dismiss the no sim inserted warnings and carry on.

thanks for the replies - all done now - as suggested it really doesn't matter which way you do it - I inserted the new sim, then ran setup (Windows phone) then followed the O2 online process for swapping sims - despite the 'may be 24 hours' warnings the swap was done within a couple of minutes.

Now I just have to get used to some of Microsofts weird ways after many years of Android..
