Basically, you’d purchase reseller packages from the Reseller Credits page. Once your order’s been processed, you’ll get a reseller panel (and login) loaded with the credits you’ve purchased.
You’ll use those credits to sell service to others. Each credit = 1 month. If you purchase 25 credits, you can sell 25 months of service across all your subscribers.
To add a subscriber, you’d simply go into your panel and add a MAG device or Kodi line (they’re simple forms).
For Kodi, you’ll have to give the subscriber a username and password. MAGs just use MAC addresses.
You cannot give your own trials, nor can you create your own resellers.
