Is there any suspicion or resemblance between the international telecommunications company mentioned in the question and the companies "Business Kom" and "Gold Quest" in terms of their mode of operation or their Shariah ruling?

It is clear that the telecommunications company will sell you prepaid communication cards or that you will subscribe to their service with an upfront payment. You are permitted to sell this service to others, and there is no sin in it, because it falls under the category of selling usufructs (benefits). However, dealing with companies like Business (Biznas) and others that operate on a network marketing or pyramid scheme basis is a forbidden transaction.
