AT+QMBNCFG="AutoSel" enabled does not restore default profile on SIM exchange


I have modified the PDP contexts (AT+CGDCONT) manually. AT+QMBNCFG=“AutoSel” is enabled, so I would expect that when I exchange the SIM cards and reboot the modem, the manually added or modified PDP contexts would be restored by the SIM or provider defaults.
Is there some write-protection flag which needs to be cleared?

I found a workaround:
When I disable AutoSel and manually select any MBN profile, it will replace the PDP contexts. When I enable AutoSel again, the provider defaults are restored.

Is there a better way?
