FAQ and support: Questions? Call us at 514-578-6982 between 10:00AM and 10:00PM Pacific Time. We are located in Canada. We would love to assist you.

Q: How does it work?
A: Simply plug the device in line with your existing network. Place the antenna as high as possible, preferably near a window with no obstructions for the best performance.

Q: Why choose Radacat?
A: We are the only distributor that is able to ship immediately after you place an order. The current average network earning is 0.15HNT per day. By shipping your hotspot faster than all other hotspot distributors, we ensure that you can start earning right away! The wait time for receiving a Bobcat or Nebra hotspot is generally around 4 months, which means you are missing at least 18HNT! And 18HNT is around 720USD!!

Q: Why should you mine HNT?
A: Since August 2021, the price of HNT has doubled. So far the highest price on record was approximately 56USD per HNT, while HNT was only around 15USD in August 2021! HNT is the cryptocurrency that will be used by major IoT projects. This means that its price will continue to elevate, but HNT supply will decrease over time. It is getting more and more difficult to mine HNT because there is a limited supply of it. Don't miss the chance to earn your HNT. You should not wait for 4 months for a pre-order because you may miss a major part of this crypto mining opportunity. You got to act fast!
