Introduction: The Magic of the Hong Kong Haha Card

Hello everyone, I’m Ping Tou Ge. Recently, a fan shared an intriguing discovery — the Hong Kong Haha Card, traditionally a physical SIM card without eSIM support, can surprisingly be converted into an eSIM! This revelation caught my attention because it turns a simple, no-frills card into a versatile mobile solution, especially for travelers or people who need a reliable number without hefty costs. Many might overlook this, but the Haha Card is genuinely a "super card" with impressive features: it costs only 10 HKD annually for a number, no registration required, no fixed monthly fees, and it supports calls, data packages, and internet usage. Unlike other local SIMs, this card combines multiple functions into one, making it a standout choice.

Why the Haha Card Is a "Super Card"

Before diving into the conversion process, let’s understand what makes this card a “super card.” Here are some key advantages:

Low Cost: Only 10 HKD per year to keep the number active.
No Real-name Verification: No complicated registration, easy to obtain.
No Fixed Monthly Fees: Flexibility to use as needed.
Calls and Internet: Supports calls, buying data packages, and internet access.
Flexible Internet Solutions: Suitable for both local and international use.
Ease of Top-up: Inexpensive recharge options via the 3HK official website using WeChat, Alipay, or bank cards.

This combination of affordability, flexibility, and multi-functionality makes the Haha Card highly attractive, especially as a backup or travel SIM.

Essential Requirements Before Conversion

Now, how do you convert this physical Haha Card into an eSIM? Here are some necessary conditions:

Device Compatibility: Only overseas version iPhones support the eSIM conversion feature, specifically those running iOS 16 or above.
Supported Devices: Domestic iPhones and Android phones don't support this conversion. For Android, only certain overseas models with eSIM capability might work, but I haven't tested all.
Connectivity: Your phone must be connected to Wi-Fi to initiate the process. Wi-Fi connection, with or without a VPN, is acceptable.
Preparation: Make sure your phone’s iOS is up-to-date to leverage eSIM features.

Note: After conversion, the physical SIM card becomes useless, and you won’t be able to manage the plan or recharge via traditional apps. But, as explained later, there’s a workaround for recharging.

Step-by-Step: Converting Haha Card to eSIM

Here’s how to turn your Haha Card into an eSIM:

Open Settings: Head to your iPhone's Settings.
Access Cellular: Tap on Cellular or Mobile Data.
Select Haha Card: Find your Haha Card in the list.
Start Conversion: Scroll down and tap Convert to eSIM.
Confirmation Pop-ups: You will receive two prompts; confirm you're ready.
Proceed with Conversion: Click Convert to eSIM again.
Authenticate: Use the side button (power button) to confirm.
Waiting Period: The process takes approximately 2 minutes, during which your device will download the eSIM profile.
Acceptance of Terms: You’ll see terms and conditions; agree to continue.
Cost Deduction: The system deducts 28 HKD for the conversion fee.
Completion: Once finished, your physical SIM can be removed, and the eSIM is active.

Tip: Keep your device connected to Wi-Fi throughout this process to ensure a smooth transition.

Post-Conversion: What Changes?

After successful conversion:

Your physical SIM becomes inactive; simply remove it.
The software management of the plan is disabled; you cannot buy or recharge data via the app anymore.
You can still receive verification codes, such as WeChat or WhatsApp, and the number remains active.
Recharging: To top-up or extend the number, I recommend visiting the official 3HK website, which supports WeChat, Alipay, and UnionPay. A recharge of 10 HKD can extend the number for 365 days.

Note: This conversion is mainly suitable for those seeking a reliable, low-cost number for long-term use. It’s less ideal if you need to regularly buy data packs or manage your balance on the app.

Practical Tips and Limitations

While this method unlocks many benefits, be aware of some limitations:

Software-Only Limitations: After conversion, the app-based functions for buying data and managing the plan seem disabled. But for receiving SMS verification and basic connectivity, it works fine.
Recharge Flexibility: Since the app is unavailable, using the official 3HK website is the best way to recharge.
Device Restrictions: This process is exclusive to overseas iPhones running iOS 16+; domestic iPhones or Android devices don't support this feature.
Potential for Future Updates: Apple may expand eSIM support, or third-party apps may provide solutions, so stay tuned for updates.

The Fun Part: Why This Matters

This process transforms a relatively simple, cost-effective SIM card into a flexible, eSIM-enabled, multi-functional number. It saves physical space in your device and simplifies management. Imagine traveling with just your iPhone, no physical SIM slot needed, yet maintaining a reliable HK number that supports calls, data, and online verification — all at a minimal cost.

Plus, the fact that you don’t need to bother with complicated registration, nor pay hefty monthly fees, makes this an excellent choice for long-term users or travelers looking for an economical solution. This revelation about the Haha Card’s potential is a game-changer.

Final Thoughts: The Future of the Haha Card

If you’re an overseas traveler or someone who needs a secondary number in Hong Kong, this trick is definitely worth trying. It showcases how sometimes, hidden features or workarounds can unlock a new level of usability for seemingly straightforward products.

And here’s a little tip: While this conversion process is currently limited to iOS 16+ devices, keep an eye on software updates and community discussions — the landscape of mobile plans and SIM technology is always evolving. Maybe soon, Android users will enjoy similar capabilities, or the companies behind these cards will officially support eSIM.

So, next time you think about dialing into a reliable, low-cost Hong Kong number, consider turning your Haha Card into an eSIM — it’s a simple process that packs a big punch.
