Do I need an international phone plan?

No. Buy a local SIM card at Seoul airport for $15-30 (7-10 days unlimited data) or use an eSIM from Airalo ($12-15). Much cheaper than roaming. Takes 10 minutes at any convenience store. Your home carrier will charge $5-10 per day for roaming.

Will my phone charger work in South Korea?

Only if it's 220V compatible—check your adapter's label. Most modern USB chargers are, but the outlet shape is different. You need an adapter or multi-outlet converter. Don't try to force it.

Do I need to bring a laptop?

No. Literally everyone travels in South Korea without one. Your phone does everything. If you absolutely need a computer, Namsan has internet cafes ($1-2 per hour) available instantly.

Is WiFi reliable enough to skip mobile data?

Yes for hotels and cafes, but no for navigation and museums. Buy mobile data. WiFi coverage is excellent but not guaranteed everywhere you'll be walking.

Can I use Google Maps in South Korea?

Yes, Google Maps works fine. But also download Naver Map because some Korean businesses only show up there. Both work perfectly once you have data or download offline maps.

Should I buy electronics in South Korea to bring home?

Only if you need them for your trip. Electronics bought in Korea are region-locked for warranties and likely use 220V. If you want something, use it during the trip and leave it, or bring home only unlocked items.

How to Pack Tech Gear for a Family Trip to South Korea

Bring a universal power adapter for Korean outlets, a portable charger for long sightseeing days, and your phone—South Korea's tech infrastructure is excellent and you won't need much else. Leave bulky electronics behind; Korean hotels and cafes have reliable WiFi and USB charging everywhere.

Get the right power adapter. Buy a Type C/F universal adapter before you leave. Korean outlets are 220V, 60Hz and use two round pins (Type C) or two round pins with a grounding pin (Type F). A single multi-adapter that handles both types costs $15-25 and works for every family member's charger. Don't rely on finding one in Korea—prices are triple.
Invest in a shared portable charger. Get a 20,000-30,000 mAh power bank that can charge multiple devices simultaneously. You'll use it daily on subways, at temples, and during shopping trips. Something with two USB-A ports and one USB-C costs $30-50. One per family works better than individual ones you'll forget.
Download offline maps and translation apps before departure. Install Google Maps, Papago (Naver's translation app), and Naver Map on every family member's phone. South Korea has excellent mobile data, but offline maps prevent panic if you lose signal. Download the South Korea maps for Google Maps too.
Set up mobile data options. Choose between a local SIM card ($15-30 for 7-10 days unlimited data), an eSIM from Airalo ($12-15), or an international roaming plan from your home carrier. Local SIM is cheapest but requires going to a convenience store at the airport. eSIM is easiest if your phones support it. Roaming is most expensive but requires zero setup.
Bring charging cables and a small hub. Pack one USB-C cable and one Lightning cable per person, plus one extra of each. Bring a small USB hub with two USB-A and one USB-C port ($15-20) so kids can charge devices in the hotel room simultaneously. Korean hotels have limited outlets near beds.
Skip most other tech. Leave behind: DSLR cameras (your phone cameras are excellent), laptop (internet cafes exist if you need one), portable WiFi router (data is cheap), and extra batteries (charging spots are everywhere). Your phone is your camera, map, translator, and ticket holder.
Get your family on a messaging app. Before you leave, make sure everyone in your family has WhatsApp, Telegram, or Line installed. It works over WiFi and mobile data and prevents you from paying for international texts. Set a family chat group now.
