Hi Mary, The phone picks up the settings itself. The only thing you may need to change, as I did on my 5S, is if you go into Settings, Mobile Data, then select Access Point Names and select Giffgaff, the user name was set by my Sim to Vertigo. Just change this to giffgaff all lower case, leave the password blank and it does work better.

I am happy to buy goodybags but wondered how difficult it is to change the setting on the iPhone once the sim has been activated, as I see some people seem to be having problems connecting.
