🛂 eSIM vs Carrier Roaming vs Local SIM — Which is best?

AspecteSIMCarrier roamingLocal physical SIM
7-day price$5–12 (best value)$50–110 (expensive)$5–15 (cheap)
Keep KR number✓ Dual SIM✓ Native✗ KR off
Instant on arrival✓ Pre-install✓ Auto△ Need shop
Multi-country✓ Regional plans✓ Auto switch✗ Re-buy each
HotspotMostly ✓ (Holafly partial ✗)✓✓

💡 Bottom line: For 3–30 day trips with a dual-SIM phone where you want to keep your KR number, eSIM wins. Watch for sub-$50/month carrier roaming promos that may also be competitive.
