What about roaming and my mobile phone use during my travel?
The EU has decided that, as of 15 June 2017, there will be no roaming charges anymore for EU residents travelling periodically within the EU. You will be able to use your mobile phone with the SIM card from your country of residence when you travel to other EU countries, with the same prices and allowances for calls, texts and data usage that you have at home. Over the last decade, EU rules have already significantly reduced the cost of using mobile phones and smart devices abroad by capping prices. Between 2007 and 2016, roaming prices decreased by more than 90%.
