Common questions we often get asked are within the common overlap and synergy between HLR Lookup and Bulk SMS, including how to make Bulk SMS messaging more successful.

The Home Location Register (HLR) is the database of mobile subscribers for the mobile network in question.  It also keeps track of the user’s location on the mobile network, (or another mobile network if ‘roaming’ - Virtual Location Register) so incoming calls and messages can be routed through the correct tower.

With high number portability rates worldwide, it has become difficult to deliver precise SMS to these mobile numbers, because SMS messages are sent on the first network and it fails delivery. This has lead to the use of HLR Lookup for Bulk SMS, something that at txtNation we are very informative about.

 

HLR Lookup allows you to identify numbers ported to another network (MNP) and any invalid numbers.
Where number portability is high in some markets across the world, HLR increases in value even further.

 

Virtual Location Register
The Virtual Location Register is a database which contains information about all the mobile subscribers which are currently located in the proximity of the MSC. A new record in the VLR is served when a new mobile subscriber is detected in the MSC’s serving area. txtNation have recently added the VLR component to our HLR API options (see below).

HLR Lookup is available for all operators globally via the txtNation gateway. Our HLR platform delivers results rapidly and accurately through HTTP and XML API. As time has gone, there is more mobile portability customers than ever before and as a direct result HLR Lookup has now become a fundamental tool for Bulk SMS messaging.
