Lumia 925 Vod-DE (with UK ee sim) freezes if 3g and over whenb browsing

[richtayrich]

Hi All,
I'm very confused as have just entered the WP world on maybe the wrong way..

I bought a Lumia 925 off a chap in Germany which states vod-de in the 'about' area.

I have put a new EE sim in the phone and it call out, sends receives texts perfectly. The only issue I have is with the data browsing.

I can surf the net via wifi all day long...if however, i dont use Wifi and use the sim (which has 50mb odf data roaming with it) all works fine on 2g, but as soon as I try 3G or 4g the phone instantly locks up and needs resetting..

Is this phone locked to Vodaphone even though I can call / receive calls, send and receive txtx, mms etc?

or is the phone duff...!

Thanks in advance
