The Nokia 8.1 has arrived in the UK and it can be yours for 380. Currently, only the 4/64GB model is available, with Blue/Silver and Steel/Copper color options.
You can find it at Clove UK. Note that this phone is a successor to the Nokia 7 plus, which made its debut in March last year at 350 (it has since dropped to 288).
We checked, but there are no other (legitimate) stores offering the Nokia 8.1 at the moment. If you find something we missed, leave a link in the comments. No carrier deals yet, either.
