HLR Lookup

HLR stands for Home Location Register and as a database of mobile phone numbers offers detailed information for every number worldwide. Validate your number inventory for invalid numbers or check their existence in advance, e.g. when entering a mobile phone number. Depending on the network, you will receive additional information on the current roaming network, whether a number is active and much more.

In your sms77 Webapp login, you can validate contact lists as a whole without having to select each individual number.
