Greetings all. I will be travelling in Mexico for about 5 weeks. During this time I will need to stay in contact with my children whilst they are holidaying in Argentina and upon their return to Australia. I will also need to stay in touch with my daughter as she will be travelling alone from Argentina via Bogota to Mexico City as we plan to meet up and travel together. So... how am I best to go about this? My Spanish is minimal. A computer with Skype or a smart phone. I have no idea really but need to sort it. Cheers and thanks.
