No sane people use iPhones where I live. It was a thing of glamorous girls and people not doing actual work for some time, but now even them I don't see with iPhones.
For me personally - as it's something I need, but not something I want to invest into, nor something I like, the Android phone I use for these things (another SIM) was almost as cheap as the dumbphone I use for calls. Comparable to groceries for a week.
I don't think there are iPhones one can buy for that price, ha-ha.
