HLR requests and Ping SMS-Quick verification tools
to clear the database of your phone numbers
If your database has not been checked for more than a month, we recommend updating it using HLR requests or ping-SMS.
1 Check and update
contact database

Some subscribers may
be out of the access zone
or change the number.
The system determines
inactive numbers
and independently
removes them from the database.

2 Recognize the operator
or subscriber status

By accessing the database of GSM, TDMA and CDMA networks, you can specify the status of the subscriber in the network
and identify the mobile operator. This is important if the client
specified only the number or changed the provider.

3 Send it
active clients

Mobile operators write off money
for sending, not for delivering SMS. Cheaper to check
database, how to pay for mailing to all contacts,
some of which are not active.

Calculate the benefit of HLR queries

Problem Many subscribers change their mobile operator without losing their number. Knowing a person's phone number, you can't be sure which mobile network subscriber they are actually on.
Imagine that you have to manually check hundreds or thousands of numbers from the mailing list database. This is a long and painstaking work, which is better handled by technology. Only an HLR query can solve this problem in automatic mode.
Solution HLR Requests (Home Location Register) —
this is a centralized database that collects information about subscribers of mobile networks of GSM operators.
HLR requests are needed to clean the database, so that without notifying the client, you can find out whether his phone number is being served or not.
Most often, such requests are needed when more than a month has passed since the last mailing.
On average, one ad message contains
150-200 characters are 3 SMS. Sending such
Messages cost approximately 10,20 ₽.

Sending to all numbers without verification If you send messages with a length of 160 characters (3 SMS) to 100 000 numbers from the database, then the service will cost 1 020 000 ₽.


Economy If you first check the database and delete the inactive numbers, then the remaining 67 000 clients will receive advertising messages. Such a mailing list will cost in
683 400 ₽ instead of 1 020 000 ₽. The total cost of mailing with pre—verification is 783 400 ₽.
Checking saves 236 600 ₽.

What is the benefit of Ping-SMS

Problem It is important to send messages only to active numbers before mass mailing about the beginning of the promotion, the receipt of goods or the update of the cost of the service. This way, customers will receive up-to-date information, and you will not overpay for sending SMS messages to inactive numbers.
To get 100% accuracy of information about active numbers in real time, you can only use Ping-SMS.
Solution Ping-SMS are hidden binary SMS messages that are sent to the client's phone number. Such SMS messages are not displayed in the phone, but they transmit information about the number's activity. The service helps you quickly and accurately check:
- a small database, when the accuracy of the check is especially important;
- a database that has not been updated for a long time to remove inactive numbers and save on future mailings.
