I was in Thailand in 2017th - mobile internet with 4g was almost everywhere, including small islands. It was a huge contrast to Germany where you need to get 15 minutes drive from most of cities to get only Edge at best, or no mobile coverage at all

For mobile coverage and speed, I've found Japan (I've been from Ishigaki to Shiretoko in the past few years) to be pretty world class (assuming your device supports the proper bands - for anyone visiting, refer to https://www.frequencycheck.com/countries/japan ). For wired connections, almost every new building in Tokyo has fiber, and 10Gbps support is pretty common (NTT, Sony, Softbank and others all offer it) while I don't believe it's widely available at all in Vietnam.

Anyway, everyone will have their own experience, and I haven't been in Vietnam since before the pandemic, but last time I was there (4 cities and a few out of town trips), while I had OK connectivity, I wasn't blown away by it vs Japan or other places. I'd take Japanese traffic safety and street sanitation over Vietnam every day of the year though.

My colleague in Tokyo has 10Gb internet in his apartment.

The future is already here – it's just not very evenly distributed

not true, im vietnamese and the internet in the us is faster in many regions

Interesting. Where in Japan and where in Vietnam?

And when in Vietnam was it via Vintel [EDIT: Viettel - doh I need my noon coffee]?

Japan: Tokyo Vietnam: Ho Chi Minh city

Vintel, yes. I also noticed free wifi at restaurant and cafes were much faster in Vietnam as well.

> Ho Chi Minh city

D1 and D3?

And yea Vintel [EDIT: Viettel - doh I need my noon coffee] makes sense - they're the military monopoly on telecom in Vietnam.

Vintel was always slow for me, but they were also trying to MITM and my setup was always evading that.

Who was your mobile operator in Japan?

it's Viettel not Vintel
