If "for most is unlimited" you mean "most don't use up all their data", then yes. If you mean "most have unlimited data plans", then see links above.

EDIT: apologies for the statista link, it wasn't paywalling me when I first looked: it shows about 12% have unlimited data.

I just asked around (~100 people) and nobody I know has unlimited mobile data here in the UK. As you can get 120gb/month for £20 and unlimited for £40 on a 12 month sim only contract, I think not many people using more than 120GB/month so no good reason to pay double for it.

As anecdata, I cut my package back to 5GB at the start of the first lockdown as my mobil data usage went to nearly 0 since wifi at home and did not run out of data during the last year. I assume anybody who was able to do that done the same.

>UK Mobile Data for most is unlimited

I very much doubt this is the case given the number of tariffs with data caps
