HLR Lookup… HL What?!?
HLR Lookup (Home Location Register) is a powerful tool that allows you to check the validity and location of mobile numbers…in short, think cost saving!
HLR stands for Home Location Register. It is a service of mobile number (MSISDN) validation and information.
- Clean up a database of mobile numbers from invalid/deactivated numbers
- Know who is currently roaming
- Know which numbers have been ported to another operator
- Reduce costs by having updated information on the recipient numbers
- Optimise messaging initiative (e.g. more effective SMS campaign)
- Increase revenues
Nowadays, mobile subscribers regularly change mobile network operator, either keeping their original number thanks to Mobile Number Portability (MNP) or choosing to change mobile number in order to get latest phone model or in response to special offers by network operator.
As a direct consequence, it is becoming increasingly difficult to ensure the successful or effective delivery of text messages and control the cost of the SMS sent.
clickSUMO introduces the HLR Lookup service, which allows you to check the validity of a list of mobile numbers with extended details about those numbers (e.g. operator identification and roaming information). By running a HLR lookup you lower costs by choosing the correct route for SMS delivery as well as optimize your SMS initiative by avoiding sending SMs to inactive numbers and reduce unnecessary associated costs.
Use case scenario
Let’s take a simple example:
Imagine that you want to send an SMS campaign to 1 million people from your database.
If we take a price of 3ct per SMS, for example, the cost of your campaign would be 30,000 Euros.
BUT, and there is a “BUT”, what you didn’t know was that 200,000 of these people in your database have changed mobile number or their SIM is no longer active. SO you just wasted 6,000 euros (or 20% of the cost of your campaign) sending an SMS that would never reach its target.
With HLR Lookup, we first run a check on your database of numbers. In our example, your campaign would have been more effective as would have sent your SMS to only 800,000 valid mobile numbers, and spent 24,000 Euros instead of 30,000.
You run a check on your list, and then we return to you only the valid numbers so you can run an efficient SMS campaign. It’s that simple!
But there is more… by running a check on your mobile numbers before sending them SMS, you can determine who is currently roaming, so you can take an informed decision on whether to keep them (or exclude them) from your SMS campaign based on costs of SMS delivery in that route where the subscriber is currently roaming. You can also filter out all recipients that are currently roaming abroad when running an SMS campaign that is time or location sensitive.
How does it work?
Leveraging on our global network of owned-and-operated SMSCs, with multiple geographically diverse connections into the SS7 mobile signalling network, and our full access to operator Home Location Registers (HLRs), we are able to offer the HLR Lookup service to give you the most detailed information available in the market.
Access is via a high-performance asynchronous API, based on industry-standard SMPP v3.4 or HTTP.
For Mobile Operators
HLR Lookup Advanced is tailored to meet the demanding requirements of Tier1 and Tier2 mobile network operators. Our service provides high-speed access to complete MSISDN information, including HLR, home network details (e.g. MCC/MNC, country prefix and ported status) , and visited network information (e.g. where the subscriber is roaming).
For Service providers
Effective Least Cost Routing (LCR) is key to maintaining already tight margins. Our HLR Lookup service allows service providers to check number validity and determine the correct mobile operator for a given phone number before a call attempt is made or SMS submitted.
With a cost as low as half a cent, HLR is a cost-effective way to control your SMS spending efficiently.
