Hong Kong eSIM Plans

No, the firewall does not apply here. Unlike Mainland China, the internet in Hong Kong remains open and uncensored. You can freely access Google, Facebook, Instagram, WhatsApp, YouTube, and all other Western apps without needing a VPN. Our eSIM provides you with unrestricted access just like you are used to at home. 

Yes. Hong Kong is a major global business hub. Our eSIM supports Personal Hotspot (Tethering), allowing you to share your secure data connection with your laptop or tablet. It’s perfect for working remotely from a coffee shop in Causeway Bay or during a convention at the HKCEC. 

 This specific plan is valid only within Hong Kong. Even though Macau and Shenzhen are just a short ferry or train ride away, they have different telecom networks (and China has firewalls). If you plan to visit the Greater Bay Area (HK, Macau, China), we highly recommend our Asia Regional or Global eSIM plans to stay connected seamlessly across all borders. 

Yes. Hong Kong moves fast, and so does our internet. You will get high-speed 4G/LTE (and often 5G) data. This is essential for reloading your Octopus Card on your phone, using the MTR Mobile app for train schedules, or navigating the busy streets of Mong Kok with Google Maps. 

 The validity period starts only when you activate the eSIM by connecting to the network in Hong Kong. You can install the eSIM at home before your flight, and the days will only start counting down the moment you land at Hong Kong International Airport (HKIA) and your phone picks up the local signal. 

No. This is a data-only eSIM. It does not come with a local phone number for calls or SMS. However, you can use WhatsApp, FaceTime, Skype, or Zoom to make voice and video calls over the data connection. This allows you to stay in touch without paying for international voice roaming. 

Yes, for convenience. Buying at the airport or 7-Eleven requires queuing, currency exchange, and completing the mandatory ID registration process. With Cellesim, you buy online, receive the QR code instantly via email, and land in Hong Kong already connected—allowing you to order an Uber or check the Airport Express schedule immediately. 

No. While buying a local physical SIM card in Hong Kong now requires strict mandatory ID/Passport registration due to government regulations, Cellesim travel eSIMs are typically exempt from this hassle as they are roaming-based data plans. You can buy online and connect instantly without uploading your passport or personal details. 

 Hong Kong is a dense urban jungle, so signal penetration is key. Our eSIM connects to the city’s premium networks, typically CSL, SmarTone, or China Mobile HK. These providers offer excellent 4G/5G coverage, ensuring connectivity whether you are in a high-rise in Central, hiking Victoria Peak, or visiting Disneyland.
