https://community.o2.co.uk/t5/Apple/iPhone-6S/m-p/912655#M139579 Hi, just reserved a new iPhone 6s from Apple. I'm due an upgrade with O2 so have just upgraded SIM only. Will the new iPhone work ok with current SIM? I currently have a 5S.

I've always done the upgrade through O2 and never bought from Apple, so was unsure how it all worked.
