Me and my family will be going to Orlando in August but my sister will want to phone her boyfriend as he isn't coming and as international calling on pay monthly and pay as you go to the UK from US is rather expensive with O2 being the cheapest at £1.02 per minute.
I was told to look up the Net10 prepaid phones at Walmart which are $25 which includes 750 minutes but unsure if you can use these to call the UK?
Another thing I was told to look up is a phone card? The villa we're staying in has free calls within US but not international (there are a few which do that but sadly this villa isn't one of them). What exactly is a phone card? Where can you get them and how to use them?
Any help with be highly appreciated,
