As of 15 May 2019, European law (Regulation (EU) 2018/1971 introduced price caps on the cost to Irish consumers for making calls or sending SMS text messages from Ireland to a fixed or mobile number in another EU Member State as below.
Irish consumers are charged a maximum amount of:
• 19 cents (+VAT) per minute for calls made (including any connection charge) and
• 6 cents (+VAT) for each SMS sent from Ireland to an EU Member State
Now that the UK has left the EU, and the transition period after Brexit has come to an end, Irish consumers are not entitled under EU law to the same pricing for calling and sending SMS text messages to the UK. Notwithstanding this, ComReg understands that in many cases there will be no immediate changes, however it is advisable to contact your provider to check (confirm) the up-to-date prices that may apply when making calls or sending SMS text messages from Ireland to the UK.
