Destination note / KR
Choosing a South Korea eSIM
Start with your trip length and whether you need to share data or receive calls and SMS. The “right” plan depends on those requirements, not on an unlimited label alone.
Provider pages checked 7 October 2026. Prices are listed in USD and may change by market, tax and checkout.
Three plan details to compare
- Validity: compare the full number of travel days, including arrival and departure.
- Hotspot allowance: confirm whether tethering works on the exact product and how much shared data is included.
- Voice and SMS: if you need a Korean number, verify that exact plan includes one. Data service alone does not establish local voice or SMS support.
Current 7-day examples
| Provider | Listed plan | Published price | What to verify |
|---|---|---|---|
| Ubigi | Unlimited · 7 days | US$25 | Plan-specific speed and fair-use terms |
| Airalo | Unlimited · 7 days | US$29 | Plan-specific speed and fair-use terms |
| Holafly | Unlimited data plan | Check provider checkout | Holafly states 1 GB/day can be shared by hotspot |
These provider listings share a 7-day validity and the advertised “unlimited” label for Airalo and Ubigi. That does not establish equal speeds, fair-use thresholds, network conditions or hotspot access. Read the exact plan’s terms before checkout.
Before buying
- Check the exact phone model in the provider’s compatibility list.
- Confirm the phone is unlocked for another carrier.
- Install while connected to reliable Wi-Fi, then follow the provider’s activation instructions.
- Keep access to your home number if it receives bank or account verification codes; check your home carrier’s roaming prices.
