Hello. I just bought a Nokia E51 from a friend who’s dad’s company got a few free off a service provider (02).
He told 02 he didn’t want them and did they want them returned, and they said no. So I bought one off him, but I have no experience in tinkering with phones whatsoever. Every time I switch on the phone, it says that ‘sim card registration failed’. I assume this is 02 having disconnected the SIM. Which is fine. What I want to know is, do I just buy a new 3G sim card? What if I want to switch provider? Do I need to get it unlocked then? Are there any specific considerations to take with that, considering it is a 3G phone?
I’m so confused. Any help would be greatly appreciated.
