I will be in Iraq in a military base is. I have a phone that is "open", which means that one of the services, maps, etc. will probably also have internet access in the database can take over. For those who have passed, and in particular, what is the cheapest way to make and receive? If there's anything technical, please explain how I am not a technician. I know I can buy phone cards 15-25 cents per minute, but I wonder whether a better choice. (For example, I can not), I had that I know, overseas and have your phone number in the United States and the tariffs for calls from the U.S. - have not thought it .... .. Some people tell me that links via Bluetooth or something so I caNo use if there is a wireless connection (always) with my phone. I have no idea how to work it - perhaps again, I need explanations of things that I am not familiar with how things work. I guess everyone aware of the information - please note that if you do not apply something in another country, not in Iraq, so I especially appreciate those who have made experience, there is low. Thank you very much!
