Frequent questions

What is HLR Lookup?

HLR or Home Location Register is a centralized data system, which contains complete information about the subscribers of all GSM operators. HLR Lookup is widely used by SMS aggregators and mobile operators to check portability of mobile numbers (MNP) in order to improve the routing of SMS traffic.

What is the HLR database?

The HLR register contains information about all GSM network subscribers. It updates automatically every time the mobile operator activates new numbers. Those numbers are stored in the database until they are no longer used. When the system recognizes that phone numbers are no longer available, it removes them from the database. Phone number validation with the HLR database application is completely anonymous. Subscribers, whose numbers are verified by HLR Lookup, will not know about it.

What kind of results can I get?

When you check the status of MNP, you can see the results in just a few seconds. The speed of obtaining information depends on the amount of your traffic launched. It takes up to 10 minutes to check nearly 10 000 numbers and receive the result in CSV format. Working with such a format makes it easier to work with mobile MNP status data for you.

How does HLR work?

In fact, HLR is a single base of operators, where they enter all the information about the connected subscribers, supplementing them with important information. As soon as a new user connects, this is reflected in the database, and on the contrary, when the number is disconnected from service, this information also falls into the information summary.

How to connect HLR of Telegram bot to the system?

To use the HLR Telegram bot service, you need a Live API key. It is generated in the WTC platform. Request help from a technical support manager or a personal manager if you do not know the key.
Go to Telegram and find @WTC_HLR_bot in chats. To start using the bot will prompt you to enter the key.
The Live API key links your Telegram account to the WTC platform. In our system, you can connect several accounts of messenger users to one key.
