RUTX50 - SIM switch every 2 hours and loss off connectivity

I found a similar issue in the forum " RUTX50 continous lose of wan ip"
I implemented the solution for to that issue, and now the both routers have been running connected for more than 2 hours.

Adding the line option dhcp ‘0’ to the config interface ‘mob1s1a1’:

  1. Log in to your router via CLI (more details here: Command Line Interfaces)
  2. Run the command vi /etc/config/network
  3. Locate config interface ‘mob1s1a1’ and press “i” to enter edit mode
  4. Add the line option dhcp ‘0’ under the mobile configuration section
  5. Press “Esc”, then type :wq and hit Enter to save and close the file

Seems there has been some changes what comes to the dhcp for the mobile interface. And I would say that those changes have been implemented in either the device or the modem FW as the only changes done prior to first observing the issue was a FW upgrade. Before that the routers had been running without any issues for several months.
