(Telecompaper) The total cost of a mobile plan showed a general decline in most countries in Western Europe in Q1 2016, while including often more data and services such as roaming, according to the latest Telecompaper research. In a survey of advertised prices in 16 countries, the Telecompaper EU Benchmark report shows postpaid prices trended lower in most countries compared to six months previously, both for plans including a high-end handset and for SIM-only plans.
