Number Context / HLR Lookup

HLR Lookup is a service to check the validity of a mobile number and identify the networks that each number is subscribed to. Most importantly, it helps to check if the phone is still active in terms of numbers validity, barred, original network name, ported number to other mobile network and etc.
