I am on the 3 network. I have tried 4 different SIM cards and the phone will not fire up with any of them, reporting "SIM Card not valid".
I sent the phone back on an RMA, and the replacement has exactly the same problem. I also see that I am not the only one to have had this problem.
Is this a general issue with the E61, or is the phone sold by expansys locked to another network? How can I tell? As far as I can tell, the only reason for this message is that the phone is locked. If it locked, could someone tell me how to get it unlocked?
I am tearning my hair out trying to get this working and I have now been without my mobile for weeks!
