You can usually find prepaid SIM card options at airport shops, convenience stores, travel counters, or mobile service points. However, buying a SIM card at the airport is not always the fastest or most convenient option.
Many travelers now prefer to buy a Hong Kong eSIM before arrival so they can connect when they land — without queues, paperwork, or changing physical SIM cards.
