Not sure this is the right site for this one but anyway someone might know. Moved back to Ireland last year from UK and still paying monthly for my 02 monthly. Wanting to get a SIM only pay as you go deal. I hardly use the number but want to keep it for a bit longer. I know some of the UK SIM only deals are monthly and the cheapest one you have to top up £10 every 4 months or they disconnect you. Also after Brexit not sure if I receive a call will I get charged roaming now?
