I am trying to unlock my mobile phone (3V 5099Y) - I was with Tesco Mobile and have now gone to giffgaff.
I received a 16 digit unlock code from Tesco (had to provide Phone IMEI) but doesn't seem to work.
I was then told by Tesco mobile customer service REP that I must not insert any o2 sim such as Tesco mobile, giffgaff or o2 when adding the unlock code, so I have now inserted an EE sim card. Once again, it does not work.
Just a little concerned as I only have 5 attempts left from 10. Contacted Alcatel and awaiting response but I believe the issue is with Tesco mobile to help resolve.
Any assistance would be greatly appreciated.
