I got this Travelon Bag for the last couple of times we traveled internationally - Travelon Anti-Theft Classic Mini Shoulder Bag (One Size, Midnight w/Teal Lining) - I got it from Amazon but apparently it's not available anymore. i liked it bc its non-slashable and the zippers can "clip" onto the bag and you can't just open it. (If that makes sense lol.) I also have smaller crossbody I would use and keep in front of me or hold.
As far as a hairdryer I just used whatever was provided by the hotel, but had a converter for my last iron (totally necessary since my hair can get weird kinks).
We did the $10/day intl phone plans, we use the phones way too much to not have them available - a blessing and a curse lol.
