Stay connected anywhere with one device – perfect for groups and heavy data users!
If you’ve already looked into SIM cards or eSIMs for Korea, you might be wondering: “Do I really need Pocket Wi-Fi instead?”
The answer is – it depends on your travel style.
Pocket Wi-Fi is one of the best internet solutions for:
- Families or groups who need to share internet
- Travelers with multiple devices (phones, laptops, tablets)
- Those who want unlimited data without SIM setup
Compared to SIM and eSIM, Pocket Wi-Fi doesn’t require a phone swap or setup, works across multiple devices, and usually offers faster or more flexible daily data limits – especially helpful if you’re uploading content, navigating maps all day, or streaming videos on the go.
In this post, we’ll explain exactly what Pocket Wi-Fi is, when it makes more sense than SIM or eSIM, and how to rent it stress-free in Korea. Let’s get started.
What is Pocket Wi-Fi?
Pocket Wi-Fi (also called portable Wi-Fi or mobile router) is a small device you can carry around that gives you wireless internet anywhere in Korea.
You simply:
- Turn it on
- Connect your phone, table, or laptop
- Use it like any other Wi-Fi network
No SIM card, no number, no installation.
Just fast internet you can carry in your pocket.
Why Choose Pocket WI-Fi Over a SIM or eSIM?
Best for:
- Groups or families traveling together
- Multiple devices (laptop, tablet, multiple phones)
- People who don’t want to swap SIM cards
- People who don’t have eSIM compatible devices – Pocket WiFi works with any Wi-Fi enabled device
- High data usage (video, uploads, maps)
- More stable or faster connections
Downsides:
- You need to carry it around
- Needs to be charged regularly
- No Korean phone number supported (no SMS or calls)
- If you’re only using 1-2 devices, SIM or eSIM with hotspot might be easier
- You must return it before leaving Korea
🔍 While SIM and eSIM can support hotspot sharing, they’re usually best for solo or light users. If you’re traveling in a group, need more bandwidth, or don’t want to worry about setup, Pocket Wi-Fi is still the most flexible.
