Mobile phone for elderly

[Joocjoo]

Any advice on easy to use mobile phones for elderly? I believe the big button phones advertised do have internet but not sure they support WhatsApp which is needed as my mother is paying extortionate price for anytime calls and international calls on her package with talk talk landline.. she doesn't have broadband so thinking of reducing her package with tt and introducing her to some type of easy to use mobile.. so much out there. Would be grateful for any advice 🙏

We got a doro for my mum , big buttons, loud, easy to use, at the time though it was just a phone, no internet options though I believe they now do-a smartphone version.

There is a phone called Chatsie which I found really good for my dad - https://www.chatsie.com/

@Joocjoo I also set up Spotify on his chatsie phone and now he listens to old music from hia past!
