Hi, I'm Hieu. I love to travel and I love technology, and I'm happiest where the two meet. I enjoy digging into how things actually work on the road, from setting up an eSIM before a flight to keeping mobile data simple and affordable abroad, then sharing what I find so your next trip is a little easier.
I've worked in SEO for six years, focusing on content written for real readers: clear answers to the questions people actually ask, not pages written for search engines. On the BitJoy blog I write about eSIMs, mobile data and staying connected while travelling. I'm based in Ho Chi Minh City.
