There are some legitimate "multilevel" telecom companies out there, don't get me wrong. It is possible to run an ethical and legitimate multilevel marketing company.
The key to look for is an organization that pays you based on revenues you produce, not the amount of sales kits you sell, or agents that you sign-up. Also, make sure that the sale of telecommunications services is the main focus of the organization. If the focus is on signing-up other agents and getting them to do the same, you are not dealing with a legitimate telecommunications vendor.
