I've a card phone 2.0 which looks like it's sim locked to UK orange. I've relocated to Ireland and when I try any non-orange sim I get a sim rejected message. As there's no orange service here in Ireland it means I can no longer use the card.

I'm surprised because there are no indications on the card that it is locked (also It's a couple of years since the card was purchased so I cannot remember the original purchase details)

Any suggestions?
