The Department has engaged with industry specifically on the issue of mobile roaming between Ireland and the UK, and in particular on the island of Ireland, in the context of Brexit. The three main mobile operators in Ireland, Vodafone, Three and Eir, which represent over 88% of mobile subscriptions in Ireland, have indicated to the Department that there will be no changes to the current roaming arrangements for their customers as a consequence of Brexit. The Department continues to engage with industry on this issue on an ongoing basis. This is fully consistent with the Government's Updated Brexit Contingency Action Plan, published on 9 July. All operators must make customers aware of any roaming charges they could incur, if and when, they use mobile devices outside of the EU.
ComReg (http://www.comreg.ie ), the independent telecoms regulator, will continue to ensure that all providers meet relevant obligations in areas such as roaming alerts. ComReg also has information for customers in relation to roaming on their website:( https://www.comreg.ie/consumer-information/roaming ), including tips on how to avoid inadvertent roaming.
