Phone needed with NO numbers

[SEM-TDM]

ND has broken his Alz products phone and the model he is used to is no longer in production.
He needs a phone with programmable buttons and NO numbers because he can remember some old numbers and will call them up to a hundred times a day. It also needs to be quite sturdy because he can get very frustrated with technology.
Does anyone have any suggestions? Thanks

Assume mobile
You want a phone with FD(N) (fixed dialling(number)) ability.
eg

EDIT
All emergency numbers will still be available.

Thanks nitram
We were hoping for a landline phone. He owned a mobile phone very briefly, kept confusing it with his TV remote control, and it disappeared without trace after about a fortnight.

Don't think you will find one because facility relies on SIM.
There are mobile phones that look like landline ones, you may find one with FDN
