At least in Europe.
"Each time a European citizen crossed an EU border, be it for holidays, work, studies or just for a day, they had to worry about using their mobile phones and a high phone bill from the roaming charges when they came home", Juncker said.
You'll instead be charged the same amount as you were when you're at home.
"Roaming charges will now be a thing of the past". If you are in the United Kingdom citizen on a United Kingdom network and trying to call an European Union country, you will have to pay extra for that. But you shouldn't assume that's the case and it's worth checking with your network before you visit Turkey.
As of today, the 15th of June 2017, these roaming charges are outlawed by the EU. This means mobile roaming on your device will be free, well, nearly because you could up paying huge sums if you don't mind some of the exceptions in this ruling.

No. If you from overseas and are in France and need to call the hotel, book a restaurant or call a tour guide, that will be treated as an worldwide call - even though you're in the same country as them at the time.
Instances of so-called "bill shock", when mobile users return home to nasty bills for using their phone overseas, have spiralled in recent years, especially since the widespread uptake of smartphones and corresponding consumption of mobile data.
So, if you have a monthly allowance of unlimited calls and texts, you can phone home for free.
Most providers have informed their customers about the new rules and which countries are included in their roaming bundle, but check before travelling to understand what your package allows you to do. Some Three deals will let you roam with no extra charges in places like Singapore, Sri Lanka and the US, for example.
However, if a person has unlimited mobile data or very cheap mobile data at home, his operator may apply a safeguard [a so-called fair use] limit on data used while roaming, the European Union executive has warned. The size of this fee depends upon the relationship between the networks, and how much flow there is between them.
Roaming charges across Europe have more-or-less been completely scrapped, starting from today.
It's not clear how the ruling will be affected when the United Kingdom leaves the European Union as part of a Brexit deal, however.
Lastly, you should keep in mind that a "very small number of operators in the EU" have been granted permission to "continue applying a small roaming surcharge after 15 June, in order to avoid negative effects on very low domestic prices".
