U.K. residents travelling to Norway or Iceland will soon have their mobile roaming fees capped, representing part of a recent trade agreement between the countries.

The U.K. signed a free trade agreement last July with Norway, Iceland, and Liechtenstein, a triumvirate of markets notable for the fact that they are not members of the European Union (EU), but the adjacent European Economic Area (EEA), which essentially extends the EU single market to a handful of additional countries in the European Free Trade Association (EFTA).
