France, Switzerland, Israel, Finland and Norway are the latest additions to its ‘Feel at Home’ service, which allows customers to roam as part of their normal allowance for no extra cost.

These five new destinations join the US, Indonesia, Sri Lanka, Macau, Australia, Italy, Austria, Hong Kong, Sweden, Denmark and Republic of Ireland, where the service has been available since 2013.

Dave Dyson, chief executive of Three, said: “Roaming charges are a rip-off and Three is tackling the issue head-on. 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.”

‘Feel at Home’ activates automatically when Three customers touch down in one of the 16 approved destinations, though pay-as-you-go customers will require an add on.

Tethering is not included in the Feel at Home service and calls and texts to non-UK numbers will continue to be charged at standard roaming rates.
