eSIM in Hong Kong- the best way to stay connected

Let’s take a look at your options for an eSIM in Hong Kong 

Hong Kong is best known as a shopper’s paradise, offering a rich gastronomic landscape built on cultural fusion, with remnants of British colonialism and Chinese culture. It attracts chefs and restaurateurs from all over the world, and boasts the most restaurants per capita in Asia, comprising authentic Chinese and global cuisines, rustic local noodle joints, fine dining, hipster microbreweries and healthy vegan cafés. You can even sample the world’s cheapest Michelin-star meal at the original branch of the legendary dim sum emporium Tim Ho Wan.


With a landscape as diverse as its population, there’s never a shortage of things to do in Hong Kong. The crowded skyscrapers and apartment blocks that Hong Kong is famous for only take up one-third of the territory. The other two-thirds are made up of lush, mountainous national parks and forests. In order to experience the greener, more tranquil side of the city, you should head out onto one of the city’s hiking trails – particularly, Dragon’s Back and Lion Rock Country Park.

Not only does the city have a lot to offer to tourists, but all major local carriers support the use of an eSIM in Hong Kong as well!
