I have a old Nokia 3410 which I have bought a prepay sim for it to be used
by the Mother-in-law.
I used the phone until I upgraded last year (O2 through Carphone warehouse)
and I bought the Simcard today from an O2 outlet.
The 3410 keeps asking me if for a security code.
I can find no trace of this on the box or manual, except for '12345' which
does not work.
the sim pack says to use '0000' or '5555' but these are no use.
Does the 3410 need unblocking, or have I to contact O2 or CPW to get help?
TIA
