is it safe to do this or should you power down?
I think deep in your heart you know the answer. Better safe than sorry, power down.
It is safe to leave the phone on when removing or inserting a SIM card.
100% safe. I've been doing this since the very first iPhone.
I do it all the time when testing various apps between phones.
Not a big deal.
