Colombia has the largest market of virtual GSM operators in Latin America. Their market share is only 10%, but, nevertheless, they transfer a lot of voice traffic. At the moment, there are 2 MVNOs operating in the country - Virgin Mobile and Movil Exito; their SIM cards are quite suitable for making money on termination.
The British company Virgin Mobile is the leader in the MVNO market in Colombia with a 5% share; more than 2 million users are connected to its network. To provide its services, the virtual operator uses the capabilities of the Movistar network. The price of a SIM card is about $ 2.9, but a default loan for the same amount is immediately available to the subscriber. This is very beneficial for voice termination, because, in fact, your expenses for buying new starting plans are fully compensated.
Movil Exito is a Colombian MVNO based on the Tigo network. The SIM cards of this virtual operator are cheaper than those of its competitor Virgin Mobile. The price is $1.45, but the card comes without an initial loan. To buy a starting plan, you will have to show your ID for SIM card registration, so you should find a permanent supplier of a large number of new cards registered with third parties.
Virgin Mobile has advantageous unlimited packages, within which one minute of a call costs up to $0.006. Movil Exito has higher call rates, its package offers do not provide unlimited voice communication, but only bonus minutes. For GoIP 32 or other GSM equipment operation, we recommend using Virgin Mobile cards.
