Caution is required in this comparison since local tariff areas are much smaller in Portugal (radius of 5 km) than in the UK (radius of more than 30 km). Many short distance calls are thus charged as regional calls in Portugal. For this reason 'local calls' in Portugal only represent 7 % of the revenues of Portugal Telecom.
As regards the cost structure of voice telephony, a distinction must be made between the initial connection, the monthly rental, local calls, regional calls and long distance calls.
The BT charging system has three types of call: local, regional, and national. Local calls are generally cheaper than regional ones, which in turn are cheaper (or sometimes the same price as) national ones. Of course, the cost of a call also varies according to the time of day and the day of the week. ... While local calls are defined in terms of charge group boundaries, regional and national calls are not. Instead, each charge group is given a location known as its charging point. If two charge groups are not local to each other, it is necessary to determine the distance between their charging points. If this is under 56.4km, calls between them are regional; otherwise they are national.
