How to set up a mobile phone card that can only use the internet, but can't answer calls and text messages?

Download and install the incoming call firewall on the mobile phone, and set to reject all incoming calls and information, which can be realized.

Incoming call firewall generally means that "unwanted" calls can't come in to avoid being disturbed (so-called blacklist). At the same time, the phone's call firewall function can also set "unwanted" calls (so-called white list). These two functions really bring benefits to consumers. Open the firewall function of incoming calls, phone books, short messages and call records to create a completely private personal space.
