Which network is best in Hong Kong?

In Opensignal's 2023 report csl shared the top coverage score with China Mobile HK, while SmarTone tied with 3 for highest time connected. Figures are a few years old, but all networks are dense in urban areas.

Is an eSIM better than roaming in Hong Kong?

For data, usually. Two weeks on Verizon TravelPass is $168.00 a line (Verizon, checked 5 Nov 2026); NUM’s two-week pick was $4.79 on 4 Nov 2026. Keep your home line for calls.

Will it work on my phone?

Dial *#06# on the phone you’re taking. If you see an EID number, it takes an eSIM. Every iPhone from the XR and XS on does, and the SE from 2020, as do Google Pixel 3 and later and Samsung Galaxy S20 and later. The phone must be carrier-unlocked. Not sure? Text PHONE and your model and we’ll check.

Does it come with a phone number?

No. It’s a data-only eSIM. WhatsApp, LINE, iMessage and FaceTime all work over it, and your home number can stay on for calls and codes.
