Did you think about skype? If you are have a computer or go to an internet cafe you can talk to the parents for very little money. You can get a subscription, and get something like 10,000 minutes a month. Or you can pay as you go your choice. If your parents download skype to their computer the call is free if you call their computer. You can call your home number or a cell phone again the options are endless. If I am in a country for a week or more I get a local sim card. If you use an international sim no one will want to call you as they have to pay for the call as well as you. You will meet friends, and you will want to be able to contact them. Look at skype as they have a lot of ways to stay in touch. Just something to think about.
