Just bought my first iPhone is there anything I should know?

I've just come from android and will be moving to iOS for the first time tomorrow. Do I need to sign up to anything?

Is gonna be a pretty weird change but ios is pretty easy and simple. The only thing you should worry about is having an itunes account so you could download apps.

Signup with Apple when activating the phone.

If you don't have a credit card you should know that there's a alternative way of making an apple id without one and by going to the apple store and try downloading a free app and then from there create the apple id
