Few tips to help you out.
1. Book only out-calls to North American 5 star hotels -
2. Don't do in-call ; language could be a huge barrier in Vietnam, and chances of scams are also high so suggesting outcalls to 5 star hotel.
3. Booking options in Vietnam
- Vietnam has a listing website for independent escorts which is used by agencies as well. This listing website is only available in vietnam. Just google it using Vitenam VPN and you will find it. again since language is a huge barrier - this wasn't useful. You will need a Google translator to use. it.
- Euro listing website has few listing as well, and that worked like charm for me - most of the girls knew little bit english and they only charged like USD 100 or so / visit.
- Agencies that support english will charge a very high price (350 something) and usually their service is not good.
I was in Hanoi Feb 2023 - The international SIM that they sell you in the airport does not work well. There were issues around data, or calling any phone number, and then calling numbers from the listing website wasn't useful as well due to language barrier - other side was hardly able to understand me, and then I got duped by one agency - he definitely over charged me for VitenamEuro list worked like charm - met 4-5 very young girls and they all loved their profession, so it was fun. I will try Ho Minh City Feb 2024 and post detailed review again, Ho Minh is more commercial than Hanoi - so it should be little easier there.
