Low-cost registered Hong Kong SIM card ClubSIM (supports VoWiFi)

This article introduces the low-cost Hong Kong SIM card ClubSIM and its alternative products.

Concept Explanation#

  • Hong Kong SIM cards are divided into stored value cards and contract cards.
  • Stored value cards: No contract, for example, a 28 HKD monthly call package. If you don't purchase it the next month, there will be no deduction or service provided. If it is still within the validity period after a few months, you can continue to purchase and use it.
  • Contract cards: Package contract, fixed monthly fee.
  • Real-name authentication: Hong Kong SIM cards need to be authenticated in Hong Kong and can be operated on mobile phones. Common identification documents are supported, such as Hong Kong ID card, Hong Kong and Macau Pass, passport, etc. Sufficient authentication time needs to be reserved. Because of the poor IT system, the authentication process may take a long time (difficult to recognize the documents). Tip: The text should not have reflections.
  • VoWiFi: Simply put, it is making calls and sending/receiving messages through WiFi without connecting to the local operator's base station.

ClubSIM Features#

Features: Stored value card, low cost for maintaining the number, can roam and make calls, supports VoWiFi (WiFi calling).

By using VoWiFi roaming, you can use local Hong Kong rates (28 HKD/month) to make calls. Without using VoWiFi, you can receive messages at a cost of 6 HKD/year.

When not using VoWiFi roaming, the only function available is receiving messages.

ClubSIM VoWiFi Roaming#

Warning: ClubSIM official does not support using VoWiFi outside of Hong Kong.

Officially not supported. Um, cough, cough.

To make ClubSIM roam outside of Hong Kong through VoWiFi, meet the following requirements:

  1. Disable the Wi-Fi Calling GPS permission in the phone's system settings, disable Wi-Fi calling location (prohibit obtaining location information).
  2. Enable airplane mode (prohibit roaming by connecting to local base stations).
  3. Connect to a WiFi that can access the international internet and has an IP address in Hong Kong (connect to a WiFi hotspot shared by a Hong Kong SIM card's data or other Hong Kong proxies that support UDP, especially ports 500/4500).

That's it.

Remember to clear DNS or restart the device.

It is recommended to directly connect to a WiFi that can access the international internet using the method of configuring the router. (Using only the applications on the phone for proxy may not work.)

Make sure to use the original Hong Kong IP proxy for the following domains:


Apple devices require additional proxy:


If you don't know how to configure, please use a global proxy.

You need to purchase the 28 HKD local call package.

Since the call package is only for local use, it is not possible to make or receive calls to/from phone numbers outside of Hong Kong.

Some users have reported that after successfully making a call using Wi-Fi calling, switching the network environment to pure mainland Wi-Fi will restore China Unicom roaming, but you can still make and receive calls.

Users have reported that even if they have purchased a local SMS package, sending messages is temporarily not supported.
