I was recently given a 2nd hand 8520 which is way nicer than my pearl, problem was that is was originally for Vodafone and we work with Orange. I got the phone unlocked for orange and the email side is excellent from our orange server at work but I cannot make or receive phone calls or SMS but the home screen is showing the orange network with full bars but any time I try and make a call the "call Failed" appears. Can anyone please help????

Bad SIM card maybe?
May have to call the carrier and see if you can get a replacement SIM

Might be problem with your phone software, one of my friend got same problem with her Vodafone and you can eliminate this problem after refreshing your phone software .
