older I phone (Shooters Hill SE18)

iPhone 6s/7/8 working please.
Hi someone was giving me one but couldn’t remember their Apple ID so I removed the ad but now back to square one.
The iphone is for disabled teen daughter who is doing GCSE’s and owing to her conditions she is allowed to use iPhone at school for calendars, rota, timers, internet etc. I just can’t afford at mo to replace her old one which was stolen in Bexleyheath last month. I wasn’t insured.
I can collect ASAP. Thank you so much for reading my request.
