Should I get an eSIM, physical SIM or pocket Wi-Fi?

Short answer

Start with what your unlocked phone supports. Compare an eSIM or physical SIM for your phone, or pocket Wi-Fi for shared data; check calls and texts separately.

A 010 number alone does not guarantee app or identity verification.

Practical next steps

  1. Check your exact phone model, eSIM support and carrier lock before purchase. Ask separately about data, local calls, incoming texts and hotspot sharing.
  2. For pocket Wi-Fi, confirm battery use, device collection and return. For any SIM, check activation and support; a Korean number does not guarantee identity verification.

What to do
  1. Check your phone’s eSIM and physical-SIM compatibility and whether it is unlocked.
  2. Decide which devices need data and whether you need local calls or texts.
  3. Check the exact seller’s activation, hotspot, collection or return, support and refund terms.

If that doesn't work

  • If your phone is locked to your home carrier or has no eSIM, pocket Wi-Fi is the option that does not depend on your phone.
Check before relying on this
  • Data-only plans may not include outgoing calls or texts. Confirm the exact plan and any app-verification requirements before buying.
  • Products sold at airports, abroad, online or by resellers may use a Korean carrier's network without being sold by that carrier. Check the actual seller and plan.
  • Pocket Wi-Fi may need charging, pickup and return. eSIM compatibility and hotspot use depend on the device and plan.
