Ubuntu Touch with OTA updates

[bingo600]

I am wondering if there is a way to disable crust, to have the calls working.
Or, at least, restart the modem without having to reboot the phone.

Some says that if you open the browser , it will enable the modem.
I guess you prob have to disable wifi and use GSM Data , in order to wake the modem by using Data

Edit:
I had (have) outgoing calls fail if i use the country prefix : +45 xx xx xx xx
I can call if i drop the prefix and just use : xx xx xx xx
