Menu to disable autodisconnect LTE network

Hopefully netgear will impliment menu in apps or web to disable or set LTE standby time. Right now, if network is dile for certain period, our modem will disconnect LTE network. Very frustrated for user who will use this modem as main internet. 

If i leave my modem at home, if my son not used it at certain period, it will disconnect network.. and cannot be turn on by using button. It must be turn on in apps only. When network is disconnect, hpone also refused to connect thru modem's wifi, and android phone will fall back to it's data or 4G.. and it make netgear apps inaccesible. 

The user need to turn off phone data and connect only to modem's wifi, and use netear app to connect again to 4g network. Too many step, and very disturbing.

Imagine, how can i ask my 5 yr old son to do the things. Hopefully there is menu to disable autodisconnect network.. and simple menu or using external button to reconnect lte network
