This is a crucial point for travelers: an EastESIM plan purchased specifically for Hong Kong is valid only within Hong Kong's borders. Your data connection will cease or incur expensive roaming charges the moment you cross into Shenzhen, Mainland China, or any other region. Since many visitors to Hong Kong often take day trips to Shenzhen, we highly recommend considering one of EastESIM's multi-country Asia plans or purchasing a separate China eSIM if you plan to visit both. This ensures continuous, affordable connectivity without surprises.
