This is my first post, so if I have made a mistake please excuse me. I recently purchased a Nokia 7250i on Virgin and tried to unlock it using the remote unlocking calculators.
The problem is that the different calculators gave me different codes, none of them worked. I triple checked the IMEI number to make sure that there was no mistake.
This is the first time that it has happened to me, where the different calculators have given me different codes, since in the past they have all given me the same code.

I have used up my 5 tries and now need help in trying to get it unlocked. Can you please suggest a different method, I have heard that you cannot unlock using a simple data cable, is this true?

Please help.
