Hi guys,
Bought a new SIM card for my girlfriend yesterday with a new number, however when you put the SIM card in, it asks for a security number (when it doesn't ask anything with the old SIM).
What could be the problem? Its a pay as you go Orange SIM. The phone is not on contract and shouldn't be locked.
We tried: 0000, 00000, 1234, 12345, and anything I found on internet but no luck (as well as her own codes). The mobile is a Nokia 5310.
Any suggestions?
Thanks!
