Why can't Samsung mobile phone card 2 make a phone call and send a text message?

If Card 2 cannot be used normally, please check whether the mobile phone does not read the mobile phone card normally.

If the dual-card mobile phone cannot recognize the SIM card on card 1 or card 2, we suggest that you:

1. Application-Settings-(Connect) -SIM Card Manager-Select a card that is not displayed-Activate (Start), then turn off and restart the phone.

2. If it is invalid, put the SIM card into another card slot to rule out whether it is a SIM card.

3. Try to replace another SIM card.

4. Back up data (contacts, text messages, pictures, etc.). ) and restore the factory settings.

(Settings-Reset/Privacy/Personal-Restore Factory Settings).
