Watchouts

High monthly living costs especially in Seoul — budget at least $1,900/month for comfortable living.
Most ISP customer support is Korean-only — setup can require a local contact or translator.
Short-term fiber contracts are uncommon — most leases include pre-installed internet but switching providers mid-lease is difficult.

Contract flexibility: Most apartments come with existing fiber. Standalone contracts typically 1-year minimum.
Outage pattern: Extremely rare. Infrastructure is among the most resilient globally with redundant backbone connections.
