Q
Why can’t my correspondent reach me?
A
Is you phone switched on ( pressed for more than three seconds)?
Are you accessing the right cellular network? Or, you may have set an
incoming call barring option.
Q
I cannot find the lock, PIN, or PUK code. What is my 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
