Hong Kong is, together with Singapore, one of the more popular transit airports.
Because of it, many travelers do not even leave the sterile area of Hong Kong International Airport (HKG), while others stay for a few days.

But I believe you will miss out when you stay in Hong Kong for a short time – there is so much to do!
Such as collecting all the Hong Kong SIM cards – there are about 27 different brands out there 🤯.
But honestly, only seven are worth your time (unless you are a domestic helper from Indonesia, the Philippines, or Thailand – then there are many more options for you).

During my two-week stay in Hong Kong in early 2023, I tried out China Mobile Hong Kong (MySIM 5G), CSL Mobile, 3 (DIY) Hong Kong eSIM & SmarTone Hong Kong (on 5G NR).
