Q&A
Q
No number is dialled when you recall a phonebook entry.
A
Check that the numbers have been saved correctly, by using the
phonebook Search feature. Resave them, if necessary.
Q
You cannot be contacted.
A
Is your phone switched on (
seconds)? Are you accessing the right cellular network? Have
you set an incoming call barring option?
Q
I cannot find the lock, PIN, or PUK code, or password?
A
The default lock code is '0000'. If you forget or lose the lock
code, contact your phone dealer. If you forget or lose a PIN or
PUK code, or if you have not received such a code, contact your
network service provider.
