Sim card for london and ireland
Hi, I need a SIM card to browse the internet and make a few calls while on holiday for 9 days - may 17-26. What's the best deal I can get and where do I buy it from? Folks on past TA articles seem to say we should avoid buying at the airport??
Also will be landing at 5.50 am at Heathrow so not sure if things are open even?
