This is my first iPhone ever and I have had a smartphone since I was 23, I am now 25. The phones size is comparable to the iphone 5, the screen is smaller than my last phone but the lightening fast speed and slim size make up for it. I upgraded from a Samsung Galaxy Core Prime that I had purchased a little over a year ago and its like going from a Kia to a Cadillac. I purchased a 9$ hard rubber case immediatley with the phone and it has a nice feel to it in my hands. I have bigger hands. Be CAREFUL to remember your pin when setting it up, I would recommend setting up a 4 digit pin code. I learned this the hard way and had to factory reset the phone after getting locked out of it a few times. Also if you are going from an android to this phone do not worry about your old sim card! This phone will come with a new one and when you get the initial setup done you will call the voicemail and a representative with My Family Mobile will connect your line!!! Also, I would recommend downloading the "Move to IOS" app, it will help you a lot with setting up your new iPhone if you are a previous android owner.
