I suspect the OP probably had no idea it was going to cost that much at the time.

An example from my travels, I'm Canadian and when I travel to the UK I can buy a travel package from my mobile phone provider that extends my home plan to cover when I'm in the UK. All great. I parked on the street in Richmond where I had to phone in to register to pay for parking. It was an 020 number, so I thought no problem. Of course it's voice to text and it failed to understand me, and on the second and third times dropped the call, so I gave up. When I get home and get the phone bill I get charges for $60 for calls to Cairo - for the parking calls, as Egypt isn't on my phone plan. How would I have known I wasn't actually calling a local London number?
