First, note that the HE910 is a HSPA modem and does not support 4G.

You can try to activate cellular data with these steps:

1. Deactivate SIM PIN with another device
2. Execute these commands:

nmcli c add type gsm ifname ttyACM3 con-name gsmconn apn <your_operator_apn>
nmcli r wwan on

As you see you need to use nmcli instead of mmcli because we are
controlling the modem from NetworkManager so it can take control of the
connection and configure routes.

HTH,
Alfonso
