Nubian z7 Unicom card can't send a message.

Hello, please confirm the tariff and package status of the mobile phone card with the communication company, try to restart the mobile phone, and then change the setting of mobile phone-more-default SMS application to Nubian address book, and send SMS in Niu Dun-application management-mobile phone permissions, and set it to all permissions. If any third-party security software is downloaded and installed, please set the SMS sending permission of the software to full permission to try.

Thank you for your concern and support for Nubian products. I wish you a happy life. Thank you.
