Do you have any recommendations regarding mobile phones? Did you keep your home-country plan or use a local provider?
Use a pay-as-you-go plan until you determine how much you actually will use it. Cell phone calls are only charged to the person making the call. If you receive the call you are not charged. But if you make a call from your home phone to a cell phone, your home phone is charged. - Dec 2008
