The plan activates automatically when you connect to a network or after 60 days.

Nomad uses 4G speed on the HKT (CSL) and Peoples (China Mobile HK) networks. It activates automatically upon network connection or after 60 days, with add-ons available for further customization. While the plan's duration is quite long, providing connectivity across 30 days, it allocates a finite amount of data, averaging to a limited daily data allowance that may not meet the needs of heavy data users.

Additionally, the cost may appear higher relative to plans offering more data, and the 4G speeds, subject to location variability, could result in slower speeds in certain areas. This variability means users might experience reduced speeds depending on their specific location within Hong Kong. Coverage might not include certain overseas territories, so it's a good idea to check with Nomad's customer support for specific coverage details before purchasing. The expected speed is 4G, but this can vary by location and time.

By providing the option to download and install digital data packs, Airalo offers connectivity across over 200 countries and regions, making it a convenient choice for global travelers.

Despite its popularity and wide coverage, Airalo's pricing for Hong Kong eSIM plans is comparatively higher than some competitors. Most its plans in Hong Kong might be expensive for budget-conscious travelers. Additionally, the data allowances provided by Airalo is not sufficient. This may not meet the needs of heavy internet users or those requiring extensive data during their stay in Hong Kong.
