In towns and cities, IDD service is provided by all hotels and post offices. Phone cards are available in post offices, hotels or in the streets. Even more conveniently, most newsstands in major cities also carry phone cards. Telephone booths in the streets are mostly for local calls.
Tourist hotels provide postal services. If you want to send important items such as antiques and cultural relics that are under customs control, you will have to ask for the help of the local branch of the international post office, instead of the small post office in a hotel.
