Connection 3g mc8705

I have a problem ,, when i activate mu M2M sim an start up PFsense It will connect , now when i deactivate the sim there is no connection anymore ,,, but when i again activate it ,, it wont come back online until i restarted the PFsense system  ,, anyone knows if i can solve this problem ?

This because we have cliens in several countries and do not want to leave the sim activated due to expensive data , we want just when its needed to activate the sim ,, but know we have to ask the client first to reboot the sysytem
