550 is out now I think. There's a 540 as well.

Honestly you would be better off with a Lumia 550 from Carphone warehouse for the same price.

It has a smaller, but higher resolution / quality touch screen. Better processor and Windows 10. The only thing that isn't quite as good is the front facing camera.

Also, the 535 has some touch-screen issues that cause it to mis-behave or detect ghost touches.

As much as I love Windows Phones (I have a Lumia 950XL) I'd advise spending an extra £30 for the new 550, it's going to outperform this in everyway and the 535 is notorious for having a very unresponsive screen.

Get a 635 cheaper than this most of the time. Mega cold for a 3G only phone. Can even get the 550 for close to this price.

Don't have a problem with mine, great for budget phone

showing sim free for 99 quid?

It was £49.99+£10 top up this morning on PAYG (all CPW phones are unlocked regardless). It had been that price for a couple of weeks. Unfortunately the price has been increased, but still cheaper than the SIM Free option (unlocked either way).

This is a great phone, and I much prefer it over the 550 purely for the screen size and cameras. The touchscreen problems were rectified a year ago.

There area quite a few bugs in the 550 due to Windows 10, which will be sorted out soon. The 535 is likely to get Windows 10 very soon, and hopefully it'll be stable.
