CPR calls with SureSMS
With a CPR lookup, you can easily and quickly see if a mobile number is in use and which operator it uses. You can do a CPR lookup directly from your browser if you have an account with SureSMS. The price is only 2 øre per CPR lookup.
HLR stands for "Home Location Register" and is the core of the GSM network. HLR is the central database for all customers who are authorized to use the GSM network.
Real-time information is often important when sending SMS messages, and with a CPR lookup, you'll know - in real-time - if the phone number you're looking for exists. This can save you from sending and paying for messages that don't actually arrive.
Global CPR service
We provide an international SMS service for professional businesses, developers and users. Therefore, our CPR service is of course also a global tool. The price for your CPR lookups is the same regardless of which country the operator is based in.
TIP - How our customers use CPR prompts:
-
A customer uses CPR lookups to validate the users who sign up for his newsletter before sending.
-
Another customer needs to send a lot of messages to the same number, but before... he checks whether the number actually exists. If not - it costs him much more than 2 cents!
-
A third customer uses it to target marketing. He knows that CBB's customers are generally younger than TDC's, so he can better target his audience by only sending to some operators' mobile numbers.
