Lookup + HLR provide extensive information about numbers. Upon request, we send an SRI request to receive information from the HRL network regarding any currently active number in the world.

HLR provides the following information:

• Network/MCCMNC: Identify a number’s country of origin as well as the mobile network to which it is registered.

• Location IMSI: Discover any given number’s current geolocation.

• MSC: Determine whether a subscriber is roaming, in which country they are roaming, and on which network they are currently registered.
