Question about Nokia 6600
Sounds like a deactivated sim card or a barred handset. Ie, reported lost or stolen
If you place an active O2 sim into a blacklisted handset your phone will not show any signal strength
at all! If the handset is a Nokia then a
"SIM card registration failed" message
will also be displayed.
