Step 3: Consider other mobile options
Still, a local SIM does not solve the problem of communicating with the folks at home. For this reason, many travellers buy a cheap calling card to make calls home while they're abroad. While this can help cut costs considerably, calling cards are not always easy or convenient to use. Usually they require entering lengthy access codes and numbers before you can make your call, and tend to run out just when you need them most. A better option may be to purchase a SIM card at home that allows you to text abroad and make cheap international calls, such as those available from companies like Lebara.
