IIRC they were also called cell phones in the UK back when analogue
cellular systems were new, complete with diagrams of hexagonal cells
covering the countryside. Mention of cell or cellular has fallen out
of use in the UK to be replaced by "mobile". But language keeps
moving on and for younger people (say, teens and twenties) mobiles
may just be referred to as "phones" now, as landline phones are
something only their parents will have.

Young people who think hand-held communication devices are for texting
and have no idea that it's possible to make a voice call?
