If you have a company or you are self-employed and live for example in Madrid you can set up a virtual number in for example Mexico D.F. (numbers 55 ..) contracting a FixedVirtual number and that your customers in Mexico think you have implantation in your country. All the calls that are made in that Mexican virtual landline are automatically derived to the landline you have in Madrid or to a Spanish mobile number that you indicate. Callers pay as a local call.
