Identify failure before retry
Message Failed means the service-centre delivery failed; No Service Centre identifies a missing stored centre number. Record which appears and ask the provider for the correct account-specific setting. Neither state justifies copying a number from another model or repeatedly selecting Resend.
What the result means: Preserve message text before deletion or SIM changes. Do not repeatedly resend, send test traffic, copy an old service-centre number or reset the phone. Ask the provider to check a real failed message using its time and displayed state; protect private message content.
Check outgoing storage without erasing
A full SIM prevents storing another outgoing message and makes the message indicator flash. First distinguish this from a radio failure. Read the stored text and preserve needed records; only the owner should delete selected unneeded messages to free space. Saving remains separate from sending.
What the result means: On the9505A, Stored to Outgoing saves a message on the SIM; Message Sent means acceptance by the message service centre, not proof that the recipient has read it. Diagnose the exact state before resending.
When to stop and get help
