This method is used to retrieve various information of a specific MSISDN
 (operator, country…) as well as the list of all products configured for
 your specific account and the destination operator of the MSISDN.
 Returns relevant information on a MSISDN (operator, country…) as well as the
 list of products configured for your account and the destination operator
 linked to that MSISDN. Allows to check if a MSISDN is subjected to a promotion

 destination_msisdn
 Destination MSISDN (usually recipient phone number). This is the destination phone number that will
 be credited with the amount transferred. Format is similar to “msisdn” and restricted to international phone number only.
 delivered_amount_info
 Setting this to “1” will return the fields local_info_amount_list,local_info_currency and local_info_value_list in the API response.
 Blank or “no” if you do not want this returned.
 return_service_fee
 Setting this to “1” will return the field service_fee_list in the API response. Blank or “0” if you do not want it returned.
 operatorid
 Operator ID of the receiving operator that must be used when treating the request. If
 set, the platform will be forced to use this operator ID and will not identify the operator of
 the destination MSISDN based on the numbering plan. It is very useful in case of countries with number
 portability if you are able to know the destination operator.
 return_promo
 Setting this to “1” will return the current  promotion related to the transaction’s operator.
