The only way to get free minutes for your TracFone is by using promotional codes sent to you. Other than this, I'm afraid you can't get free minutes. Companies don't just give things out for free, they have to make a profit somehow.
A Mobile Virtual Network Operator (MVNO) (or mobile other licensed operator (MOLO) in the United Kingdom) is a wireless communications services provider that does not own the wireless network infrastructure over which the MVNO provides services to its customers. An MVNO enters into a business agreement with a mobile network operator to obtain bulk access to network services at wholesale rates, then sets retail prices independently. An MVNO may use its own customer service and billing support systems, marketing and sales personnel or it may employ the services of a Mobile Virtual Network Enabler (MVNE).
Countries such as the United Kingdom, Scandinavian countries, and Spain are leading this business model in Europe.
