Mobile Broadband Error 720
Users might receive a mobile broadband error 720 which says “A connection to the remote computer could not be established. Change the network settings.” This error occurs if the TCP/IP protocol stack is corrupt.

Changes to the network components might corrupt the TCP/IP stack which results in connectivity issues. The computer will not be able to send any communication requests if the TCP/IP is corrupt. Users can try to reset the TCP/IP stack or install the Microsoft fix to resolve the issue. However, if the issue is still not resolved then users have to reinstall the operating system.
