Buy eSIM 3HK, China HK Macau 15 GB 30 days

An eSIM (embedded SIM) is a digital SIM card that allows you to activate a mobile data plan without needing a physical SIM card. It's embedded directly into your device and works by scanning a QR code.

Coverage depends on the selected plan. Browse destinations on this page and review the included countries and network details on the product page before purchase.

The data plan becomes active immediately after the eSIM is activated on your device. Make sure to install it just before or upon arrival in your destination country.

To install the eSIM, simply scan the provided QR code using your phone’s settings. This downloads the eSIM profile but does not activate the plan until you enable it, allowing flexibility for travelers.

Most smartphones from 2019 onwards support eSIM, including:

Apple iPhone XR, XS, and all later models
Samsung Galaxy Fold series and newer
Huawei P40 and up
Google Pixel 4 and newer
Please check your phone’s specifications for eSIM support.

Yes, most modern phones support dual SIM functionality, meaning you can use a physical SIM for calls and SMS, while using eSIM for mobile data.

An eSIM can be more convenient because installation details are delivered digitally and no store visit is required. Device compatibility, activation rules, and network availability depend on the selected device and plan.

Yes, many modern smartphones allow storing multiple eSIM profiles, but you can only use one at a time. This is ideal for frequent travelers or those managing business and personal lines.

Most eSIM5G plans are prepaid and not refillable. Once the data or validity expires, you’ll need to purchase a new plan. Always check the specific details before purchasing.

If you accidentally deleted your eSIM or didn’t receive the email, contact our support team immediately. We’ll resend the QR code or help you reactivate the plan if your device allows.

Many eSIM5G plans support hotspot or tethering, but availability depends on the selected plan, device, and local network. Check the product description before purchase.

eSIM5G offers both data-only plans and plans that include mobile data with a local phone number. The included features are shown on each product page. Your existing physical-SIM number remains unchanged unless you choose to use the eSIM for calls or messages where supported.

All our tourist eSIMs are designed for mobile phones, where they work reliably. In the case of portable Wi-Fi routers, we cannot guarantee stable performance, as many of these devices lack important features such as manual network selection.
