Speaking at KBW2026








Local knowledge
The venue sits east of the river. Budget an hour from Gangnam in evening traffic, twenty minutes at dawn.
Luma is where the real schedule lives. Check it hourly; the good ones cap at eighty people.
Card works nearly everywhere. Keep ₩30,000 in cash for the pojangmacha tents afterwards.
KBW usually lands next to Chuseok, when half the country is travelling. Book beds and trains early.
Check
Dial *#06#
If an EID appears, your phone takes an eSIM.
No EID? Don't buy this. Buy a physical SIM at the airport instead.

Questions

About two minutes. We email a QR code; scan it before you fly.
Unlimited data at high speed on LG U+, 4G and 5G. We print the network instead of hiding it.
One-for-one replacement, and any unused plan is refunded.
It depends on the plan, and checkout shows it before you pay.
