I have attempted to unlock my mrs's Nokia which is locked on O2 quite a few times. The 1st was through the free O2 service after 12 months old, but came back as failed. Then I have tried a few times through the O2 15 service. The last time failed as the credit on the phone fell below 15 needed. Unfortunately the pay and go go go deal only has 500mb data therefore takes a 1 a day for extra data. Because it can take 30 days to unlock, I think another option may be cheaper!

looking on eBay I see a seller listing this service: [Only registered and activated users can see links. ]

Do you think this will work and is safe giving over the phones IMEI code?
