HK Airport. Currency exchange & $15 Sim Card- June 2023

Short vacation to HK & China.  Data Sim was good for both HK & China. I found the HK currency exchange rate to be better than other places but RMB was not so, I waited until I arrived in China.  Next time I will compare rates with my local bank in the US.  FYI, there is pros and cons but I find Shenzhen to be more modern & economical than HK.
