Phoning home from another country can be expensive. All hotels will add a service charge to the cost of any phone calls you make from your room.
We suggest that you contact your phone carrier to find out what international plan options are available to you. Also, there are mobile messaging APPS such as WhatsApp that will enable you to exchange messages without having to pay for SMS.
The locals or hotel staff are always happy to assist as well if you have problems dialing!
