There's no reference to the 4 daily location-requests in the FAQ, or for this matter, anywhere I could find in the WaveSecure website. I had a real situation where I forgot my phone in a taxi and was surprised to find out I need to wait a day before further tracking its current location after 4 requests. Luckily I managed to get hold of the taxi driver and got the phone back. As I pay for the service I would expect a non-limited locating option, or at east a clear indication in the web site that I can only reques 4 location tracks a day, and not only get the note once I can't use the feature anymore!
This is bad service.
