ℹ
About KR 3GB for 30 days
What is KR 3GB for 30 days?
KR 3GB for 30 days is a prepaid eSIM data package designed specifically for use within the Republic of Korea. Once activated, the eSIM delivers up to 3 GB of 4G LTE or 5G-compatible broadband, lasting exactly thirty calendar days from the moment of first use. The plan is sold by eSIMania.com, a specialist provider of international eSIM solutions, and is priced at $32.70. Because the eSIM is digitally provisioned, there is no physical SIM card to insert; travelers simply scan a QR code on their device and the profile is installed automatically. The activation process completes in under five minutes on most smartphones, and the profile can be removed or re-installed without affecting the device’s warranty. The service works on iPhone, iPad, Android phones and tablets that support eSIM, and it automatically selects the strongest local LTE or 5G tower, ensuring smooth video calls and fast downloads throughout Seoul, Busan, and regional areas.
Key features

- Instant activation — QR-code provisioning enables use within minutes of purchase.
- Device compatibility — Works with iPhone, iPad, Android smartphones and tablets that support eSIM.

Who is KR 3GB for 30 days for?
The plan targets short-term visitors such as tourists, business travelers, and digital nomads who need dependable internet for navigation, translation apps, video calls, and streaming while moving around Korean cities. It also serves students on exchange programs who prefer a fixed-term data budget rather than a contract. Because the data allowance is capped at 3 GB, it encourages efficient usage—social media browsing, map updates, and occasional HD video streaming fit comfortably within the limit. Users who rely on cloud-based productivity suites will find the speed sufficient for document editing and email, while heavy gamers may need to monitor consumption to avoid throttling after the cap is reached.
How does KR 3GB for 30 days compare?
Compared with typical pay-as-you-go SIM cards sold in Korean convenience stores, the eSIM offers faster setup and eliminates the need to handle a physical card. Its price is competitive against bulk data bundles that require a longer commitment, and the 30-day validity aligns with most travel itineraries. While larger data packs provide more capacity, the 3 GB allowance balances cost and usage for moderate internet consumption. For users who already own an unlocked device, the eSIM avoids the hassle of swapping cards when returning home. In contrast, roaming packages from home carriers often charge higher per-megabyte rates and may suffer from latency, making the KR eSIM a cleaner, more predictable option for short stays.

Frequently Asked Questions
What devices are compatible with the KR 3GB eSIM?
▾
The KR 3GB eSIM works on any smartphone, tablet or wearable that supports eSIM technology and runs iOS 14 or later, iPadOS 14+, or Android 9+ with eSIM capability. This includes recent iPhone models (XS and newer), Google Pixel devices, and many Samsung Galaxy phones. Devices must be unlocked and have an active internet connection for the QR-code provisioning.
Does the data reset after 30 days?
▾
No, the 3 GB data allowance is valid for exactly 30 calendar days from the first activation. After the period expires, any remaining data is forfeited and the profile becomes inactive. To continue using mobile internet, you must purchase a new eSIM plan or extend the current one if the provider offers an add-on.
How do I activate the eSIM after purchase?
▾
After buying the plan, you’ll receive an email with a QR-code link. Open the link on your eSIM-compatible device, tap the QR-code, and follow the on-screen prompts to download the profile. Activation typically completes within minutes, after which you can select the KR network in your device’s settings and start using data.
Is there any roaming when I travel outside South Korea?
▾
The KR eSIM is restricted to South Korean mobile networks; it does not provide roaming coverage beyond the country’s borders. If you cross into neighboring regions such as Japan or China, the profile will lose connectivity and you will need to purchase a separate eSIM or SIM card for those destinations.
Can I extend the data plan if I need more than 3 GB?
▾
The standard KR 3GB plan does not include an automatic extension option. To obtain additional data, you must buy a new eSIM package or check whether the provider offers a supplemental top-up for the same country. Extensions are processed as separate purchases and will start a new 30-day validity period.
