03 · FAQs

South Korea eSIM FAQs

Q.Will my phone work in South Korea?

If your phone is unlocked and eSIM-capable (iPhone XS+ or Android 2020+), yes — no store visit needed.

Q.How much data do I need for South Korea?

For a 1-week trip using maps, translate, ride-share and social, 3–5 GB is usually plenty. Video streamers should pick 10 GB+.

Q.Can I keep my home number active?

Yes — eSIMs run alongside your home SIM. Turn off cellular data on the home line to avoid roaming charges.

Nervous about installing it?

For $3, we'll walk you through it tap-by-tap using your exact phone model — iPhone, Samsung, or Pixel — and won't let go until you're online.
