Customers of mobile phone operator Three will soon be able to use their phone in six more countries without incurring additional roaming charges.

Three said today that UK customers visiting France, Switzerland, Israel, Finland and Norway will be able to use the internet, text and call home as through they were in the UK, from 1 July.  

The move means that Three customers can roam at no extra cost in a total of 16 countries, after the US, Indonesia, Sri Lanka and Macau, Australia, Italy, Austria, Hong Kong, Sweden, Denmark and Republic of Ireland, were added to Three's Feel at Home service last year.

Feel at Home is part of Three’s effort to eliminate roaming charges completely.

“Roaming charges are a rip-off and Three is tackling the issue head-on," said Three CEO Dave Dyson. "We haven’t just reduced charges; we’ve now scrapped them in 16 destinations, making it fairer, easier and more enjoyable to use your phone abroad."

“The addition of five more countries, including France, to Feel At Home is another big step and one that marks our determination to eliminate roaming rates full-stop.

“I want customers to stay connected when they’re overseas without the fear of a nasty bill when they return.”

The Feel at Home service is activated automatically when a Three customer lands in one of the participating countries. The user’s phone will join the local network but they won’t be charged extra.

The service is available to customers on pay monthly, Pay-As-You-Go, SIM-only and mobile broadband.

Rivals O2, EE and Vodafone are yet to offer free data roaming to their customers.

The European Union is aiming to eliminate roaming charges entirely across member states, with the European Parliament recently approving the Telecoms Single Market Regulation, which could result in roaming fees being abolished by December 2015.
