No problem, you may change your tariff at the end of every month. The first tariff change is always free. Thus, as a starting cambio member you don’t have to worry about changing your tariff if you notice another tariff may be more advantageous. Any next tariff change within 12 months (1 year) incurs an administrative cost of 15 euro.
You may request a tariff change via MyCambio or by contacting the client services.
