Getting Started

Statistics will appear once your file is uploaded:

Loaded - how many numbers in the file that has been uploaded

Processed - how many numbers have been HLR'd

Saved - how many have been processed and saved into the new spreadsheet containing the results


The file is complete when the Saved total equals the Loaded.




4) Browse to Results

Browse the folder from where you uploaded the raw file and you will see a file with the same name with "-results" appended. 







5) View Results 

Open the file with "-results" appended to view the HLR data. 






How many can I load?

We have tested over 500,000 without any issues, however, as this can take some time to process (500,000 divided by 1000 per minute = 8.33 hours) for this kind of volume you might like to consider splitting the file and running on two separate PC's using the same account credentials. 


What data do you return?

- Live number - (yes / no)
- Current network - (network name)
- Original network - (network name)
- Roaming - (country roaming on name) 
- Mobile Service Center (MSC) - (number) 
- International Mobile Subscriber Identity (IMSI) - (number)
- Mobile Country Code & Mobile Network Code (MCC/MNC) - (number)


Can you return the location of the phone?

The current country where the phone is located is returned. If a user is roaming you will be able to see their home country and the country where their phone is roaming.

If you require a more precise location the Cell ID (CID) or Location Area Code (LAC) can be used to geo-locate users within a country. This can be possible on certain routes, however due to data protection, has restrictions. Please contact txtNation for a list of countries where CID and LAC is supported. 


How much does it cost? 

Please contact your txtNation account manager for pricing. 


How do you get the results?

txtNation works with many network operators throughout the world and has interconnect agreements that makes performing HLR lookups possible. 


What do the results mean?

This depends on the route, please contact your account manager or log a ticket via for the meaning codes relating to the route you are using. 


Can you whitelabel the desktop app?
