Loss of connection with profile switch

Hello,
i use two profiles on a RUTX11. The input is triggered with ignition in a car and switches the profile. So i have one profile running during parking and one during driving the car. The only difference between the profiles is the activation of gps https data sending during driving.
But: always when switching, the mobile network is reset and has to be rebuild. In homenetwork no problem because always the same network is used, but abroad during roaming the router searches new connections…
Is there a solution to keep connections during switching?
Greetings
