Phone southern Irish number

[2Rcarlin]

I live in Northern Ireland. Past few weeks my phone will not let me ring any number in Southern Ireland

Thanks @MI5 

@2Rcarlin - calling an Irish +353 number from Northern Ireland will carry a cost, and as you posted in Pay Monthly, I can only ask - have you used MyO2 unintentionally to bar, or prevent by Cap, calls to international numbers (or has O2 had cause to reduce your service for any reason)? Guide: O2 BARs or Guide: Spend Caps & Charge to Mobile on O2 

Are you close enough to a border to roam onto an Irish network and call the number for free?

@2Rcarlin To add to the advice from @pgn, when you can eventually call the number in Southern Ireland, if you and the number you're calling both have WhatsApp you can call using a WiFi connection for free.
