02 3g - how !

Hi
I'm on 02 Pay as You Go TEXT & WEB - using this sim card in my Nokia N95 8GB I get full 3G.

Using the same card in my Desire I get GPRS..

I've web chatted with O2 and they advised the phone my not work on PAYG 3G..

Yet other have it working. Any Ideas ?

The default settings work for GRPS, but I get no data through put .. Nothing at all.

Any Ideas ?

Thanks

 

yep.. it connected but no data !
I called o2 earlier. since then I can't get gprs or 3g nothing !
