Let's start from the beginning, i.e. roaming. In EU member states, we can roam without additional charges. However, "all that glitters is not gold", so let us remember that not always in a dependent territory or island of a given country we can use the Internet on the same terms as in the EU. Denmark is a member of the Union, but Greenland and the Faroe Islands (dependencies of Denmark) are no longer members of the Union. In addition, we must remember to turn off the Internet when we pass through a country that does not belong to the EU or to purchase an additional Internet subscription. For example, when you are driving a car to Greece, you must remember to turn off the Internet when passing through Serbia, otherwise the operator will charge you additional fees.
What about area codes, what exactly are they for? We are already coming with an explanation, area codes are distinguishing features of countries, thanks to which telephone calls are directed to the right place on earth. The international organization ITU assigns countries special numbers (country codes), which we must enter before the proper number when calling a person staying abroad. For example, to call Poland from abroad (which has the code 48), you need to enter 0048 or +48 on your phone. We already have the area code, we enter it and we still can't get through? Let's discuss this situation on the example of Italy (interestingly, in Italy there may be different lengths of telephone numbers), to call Italy on a landline, we have to dial + 39 06, and when calling a mobile phone, we skip 0. Until 2001, the first "0" was part of every mobile number, but prefixes for mobile numbers were shortened. Being interested in the topic, we conducted a test for you by calling landline and mobile phones in different countries. In all the countries we called (e.g. Croatia, Greece, France, Turkey) we do not have to add "0".
And now what we've all been waiting for, i.e. a mini download of area codes in the regions where we charter yachts.
