Upgrading and transferring

[Gemma222]

I am a sky mobile customer and my phone contract finished last year. I would like to upgrade my iPhone and keep the same phone number. I’ve read that all I have to do is swap my SIM card. However, I would also like to transfer all my data and information from my old phone to my new phone, and I’ve read all I have to do is put the two phones next to each other. I am wondering in what order I do these in.

Do I just put my old SIM in the new phone first and then during set up, if both phones are next to each other, it'll prompt me to transfer the info from my old phone to the new one?

Thanks!

I don't think it matters but personally I put the  sim in the phone first as it will then download the network settings the phone needs from Sky.

Personally, I transfer the data (using the setup wizard initiated on the new phone) first and then move the SIM once that's completed.
