Network Query identifies which network a particular mobile phone number (MSISDN) belongs to, as well as providing an existence check for every MSISDN queried. Network Query is an essential service in areas where Mobile Number Portability is in place.
Network Query identifies the network a mobile phone number belongs to, whilst identifying invalid and ported numbers, a service which is especially useful in markets where Mobile Number Portability is in use. By knowing the correct network information in advance, customers can avoid the incorrect routing of SMS due to MNP technical issues. This reduces the costs and effort associated with incorrect routing and thus enhances quality and speed.
The service performs an HLR (Home Location Register) request for each query within the GSM network, providing information such as:
