Is there a way to identify a phone's original network by its IMEI?
My son bought a second hand phone off eBay over Christmas (a K750i) which was supposedly unlocked to all networks and took advantage of Orange's free Pay-As-You-Go SIM offer. Orange, after a delay, a couple of days ago finally sent through all the necessary SIM updates to set the phone up for GPRS including MMS, Picture Messaging, Orange World & internet, etc. and so my son was then able to do all his mobile internet stuff all was going fine until he turned on his phone this morning when the phone displayed the message 'Inactive SIM'.
I spoke to Orange on behalf of my son and was told that the IMEI was not barred, as far as they were concerned the SIM was still active and all would have worked fine for calls until my son accessed GPRS which caused the phone to recheck which network the SIM was registered to.:?: As they they identified, by the IMEI, that the phone was not originally a Orange phone, they summised that it had not been 'properly unlocked from the old network' and it was now refusing to accept that SIM. As the phone is not originally an Orange phone they say they can't help and we need to speak to the original network operator but as the phone had had a hard reset done and had all it's network branding removed we can't find any info in the phone about what network it was originally on.
Can anyone tell me how to find out who the original network operator was?
