If you check this box we'll add your result to the Shared Cache.
This means that if any of our clients that own the same numbers as you and send it to us for a HLR Lookup, and they wish to check the Shared Cache, then we'll give them your result instead of doing a real time lookup.
As a reward we'll give you a quarter of a HLR credit back on your balance.
This not only helps reduce the costs even further for our clients but helps grow our user base. The more numbers checked through our system, the more credits we give back. It's only fair.
