£399 for 64GB, £439 for 128GB.

Today is the European launch day for the OnePlus 3T, the mid-cycle refresh of OnePlus's popular affordable flagship. The phone is available from the manufacturer's UK store with 5-day shipping times for both the 64GB model (at £399) and the 128GB variant (at £439) in the new "gunmetal" color. The elusive rose gold OnePlus 3T is still marked as "coming soon."

In addition, O2 UK is also stocking the OnePlus 3T on a range of price plans starting at £31 per month. Right now O2's only selling the phone on contract, with no PAYG price listed.

The OnePlus 3T builds on its predecessor with a faster Snapdragon 821 processor, a bigger 3,400mAh battery, a 16-megapixel front camera and tuned-up software. AC's Andrew Martonik recently reviewed the phone, and was impressed by the value it offers even at a slightly higher price point.

Even with the modest price bump, the OnePlus 3T is an amazing value. It has great hardware, slick and responsive software, amazing battery life, strong rear camera and every internal spec you could want. Even its few weaknesses, like slightly low screen brightness, lack of waterproofing and questionable software update frequency, are minimal bad marks on what is otherwise an exceptional phone.
