Work through these checks
Separate SIM and phone-security messages
Pages39–40 distinguish Insert Card, Check Card, Blocked and !Blocked. Blocked concerns PIN; !Blocked concerns PIN2 features. Bad Card See Supplier needs the provider. Record punctuation and the exact message; these are not interchangeable weak-signal warnings.
What the result means: Preserve stored contacts and managed security settings. Do not guess PIN, PIN2, PUK or unlock codes, clear memory or reset. Ask the provider to confirm account permissions for the present location.
Check the outgoing-call stage
Pages41–43 call for a rotated, fully extended antenna held vertically with clear sky, and international-format numbers. Busy Try Later differs from Restricted Area. Save the message, location and time for the provider; do not assume repeated redial will fix a permission restriction.
What the result means: Match the exact display message, antenna position and call direction before changing restrictions or replacing equipment.
Compare incoming and outgoing symptoms
Page163 separates incoming checks for Call Forwarding, Call Barring and a disabled Ringer from outgoing restrictions and the fixed-dial list. Record the existing states without changing them. A silent ring does not prove network failure, and a permitted stored number does not prove every number is allowed.
What the result means: Preserve stored contacts and managed security settings. Do not guess PIN, PIN2, PUK or unlock codes, clear memory or reset. Ask the provider to confirm account permissions for the present location.
When to stop and get help
Preserve stored contacts and managed security settings. Do not guess PIN, PIN2, PUK or unlock codes, clear memory or reset. Ask the provider to confirm account permissions for the present location.
What to tell support
Save model, exact message, antenna state, call direction, time and restriction state privately for support.
