Why can't Samsung mobile phone dual card send out A card information?

If the dual-card mobile phone card 1 (or card 2) can't send short messages, and the SIM card is loose or damaged, I suggest you:

1. Try shutting down and restarting.

2. Try to re-enter the SMS center number: Information-Menu button-Settings-(SMS) Information center number (Note: please contact the local network operator for the information center number, and the telecom card has no information center number).

3. Try to replace another SIM card. If you can send it, just go to the operator and change the SIM card.
