Will my iPhone 5SE still work when 3 G is gone?
Question marked as
I'm not too sure which iPhone you're referring to, but iPhone 5, iPhone 5s and iPhone SE (1st Generation) support 4G. So, yes, you will be able to use your phone as normal when 3G is phased out, though we don't know when that will happen.
