Suitable for: Those who only need a Hong Kong number to send and receive verification codes. This is suitable for people who frequently register or log in to overseas platforms, cross-border e-commerce accounts, and Hong Kong local services (such as AlipayHK, Octopus cards, Hong Kong bank apps, etc.), and who only need to receive SMS verification codes without requiring data usage. For users who prioritize low-cost number retention, these plans typically have very low monthly or annual fees, making them a cost-effective option for those who want to maintain a Hong Kong mobile number but have a limited budget and don't want to waste money on expensive fixed-month data plans.
