What information can a HLR status report give me?
Performing a HLR (Home Location Register) check will give you valuable information on your database subscribers. A HLR status report will let you know if numbers in your database are accurately formatted (i.e. if there are any numbers missing), if they are active, what network the user is subscribed to and if the number is roaming in another country. This information can prove invaluable when trying to keep campaign costs down – there is no point in sending messages to invalid numbers.
