I will be traveling to US (Boston) for a week on business trip in mid-July and then a week holiday in London to visit family.
What would be best way to carry or get/exchange USD and Pound?
Most transactions in US I will be doing through my AMEX corporate card but need some cash say 500USD or so just in case.
Whereas in UK, I won't be using my AMEX corporate card, so what are best options if I need to carry/take about 500 Pounds?
Also, if I need to get some US and UK mobile sim, what are my options? Can I buy them in Australia itself before travel? If so, which ones?
Thanks a lot for your help in advance.
For only a week in each country, I would use ATMs and use global roaming on my existing provider.
