Re: Easy to use 3G Mobile Phone
It might be a bit old-fashioned, being a "flip" phone but we bought MIL a Doro - 3G, and they include a basic camera:

https://www.doro.co.uk/doro-6530.html
If you want you can compare the two on that web site, although there really isn't much difference.
GPS; flash for camera; torch & a few minor bits.
The 6520 can be had for under £50 sim-free (Amazon) but the 6530 is a bit more at just under £100
BUT comes with a very handy charging cradle too (£21 to buy separately) , which the cheaper one does not. They can both also take a memory card, useful for photo's & they're cheap nowadays.
MIL has had hers for about two years now after swapping from a similar but non-3G Doro when she changed networks.
It's no all-singing all-dancing fancy phone but she likes it and hers has been reliable.
HTH
