/**
* Contains the list of carrier restrictions.
* Allowed list: it indicates the list of carriers that are allowed.
* Excluded list: it indicates the list of carriers that are excluded.
* Default carrier restriction: it indicates the default behavior and the priority between the two
* lists:
* - not allowed: the device only allows usage of carriers that are present in the allowed list
* and not present in the excluded list. This implies that if a carrier is not present in either
* list, it is not allowed.
* - allowed: the device allows all carriers, except those present in the excluded list and not
* present in the allowed list. This implies that if a carrier is not present in either list,
* it is allowed.
* MultiSim policy: it indicates the behavior in case of devices with two or more SIM cards.
* - MULTISIM_POLICY_NONE: the same configuration is applied to all SIM slots independently. This
* is the default value if none is set.
* - MULTISIM_POLICY_ONE_VALID_SIM_MUST_BE_PRESENT: it indicates that any SIM card can be used
* as far as one SIM card matching the configuration is present in the device.
*
* Both lists support the character '?' as wild character. For example, an entry indicating
* MCC=310 and MNC=??? will match all networks with MCC=310.
*
* Example 1: Allowed list contains MCC and MNC of operator A. Excluded list contains operator B,
* which has same MCC and MNC, but also GID1 value. The priority allowed list is set
* to true. Only SIM cards of operator A are allowed, but not those of B or any other
* operator.
* Example 2: Allowed list contains MCC and MNC of operator A. Excluded list contains an entry
* with same MCC, and '???' as MNC. The priority allowed list is set to false.
* SIM cards of operator A and all SIM cards with a different MCC value are allowed.
* SIM cards of operators with same MCC value and different MNC are not allowed.
