So-called "direct" mobile numbers - hot topic not only for a relatively narrow range of consumers. Many quite frankly puzzled, "Why do we need the direct number?", But from time to time forced them to call. Recent changes in legislation on communications and the introduction of the principle of CPP (Pays caller) led to a review relating to the direct numbers: some users from the expensive convenience fails, the other - on the contrary, actively buying up contracts has risen in price. His role was played by the introduction of all operators of federal "doubles", scheduled for this year's withdrawal from the commercial exploitation of rooms per unit and is constantly circulating rumors of an impending total abolition of direct mobile numbers as such. It turns out, has already taken place and future changes in this market can also be used as an additional tool in competing operators.
