They will be additional billing numbers, which report a maximum economic benefit from the first moment, with all the features available to the user.

Different numbers are available with different pricing levels.


The numbers 905 propose a unique form of payment to fully enjoy the service they have assigned.


There are also promotional numbers 902, designed to offer the same leisure or contact service, within the limits of occupation, schedule, number of daily calls, etc.

Experience has taught us that the quality of a voice product can be measured by several factors, but the most important is customer service. In this sense, Grupo Call Net has specialized in the training of agents controlling the entire process, from selection to continuous monitoring of productivity through training. Starting from this premise we have achieved a quality of service that sets us apart from our competitors and from which we have made our true differential value.
