The Nokia X6 is now available for as little as £20 per month with an additional £50 automatic cashback on a two year contract from T-Mobile.
Orange and Three UK are the other two carriers offering the phone for the same price albeit with different packages.
T-Mobile sells the Nokia X6 with 300 minutes, 300 texts and unlimited internet on a two year contract with a total cost of ownership of £430.
Settle for a 18-month contract for the same monthly outlay and you get 100 minutes, 100 texts plus internet for £340 instead on T-Mobile.
Orange's offer is the least attractive of the X6 offers available at £20 with 100 minutes, unlimited texts and only 250MB (£460 total cost of ownership on two years).
As for Three UK, its internet talker package provides with up to 300 minutes, up to 300 texts, 500MB, 5000 intra-network minutes, Skype calls and free Windows Live.
The X6 itself is a pretty good looking mid-range handset, one which comes with 16GB internal storage - unheard at this price - a 3.2-inch capacitive touchscreen, GPS, Wi-Fi, a five-megapixel camera with dual LED flash and geotagging.
It cost £449 when it launched at the beginning of the year, prompting ITReviews to say that "Despite the plentiful feature set, we can't help feeling that the X6 is expensive for what you get."
