HLR Look Up

Let your numbers be checked! Excellent way to validate and verify mobile numbers. HLR Lookup helps to enhance the accuracy and the effectiveness of mobile activities

Why should you check if a phone number is active?

Every database contains bad data, in the form of invalid numbers, duplicate contacts, and landline numbers.

The situation is aggravated by portability issues so that you can’t tell for sure by looking at the number which carrier it refers to.

Sorting through an endless database of thousands or even millions of mobile phone numbers seems to be a hard task. Luckily, we provide the HLR lookup service for making your contact database squeaky clean.

How the HLR Lookup works?

HLR database contains information about all cell phone subscribers who have access to the GSM network and gets updated each time a mobile operator activates a new number. These numbers are kept in the database as long as they are being used by subscribers.

The number that is no longer used gets automatically deleted from the database. Such numbers checks are performed in a non-invasive way so that the subscribers won’t see anything on their phones.

Squeeze the most out of your SMS marketing campaigns with HLR Lookup. This is a perfect solution for ensuring your contact list is valid and clean.
