There is no "global store" at Incheon, and to be honest, they're not that helpful, and it's still quite expensive. It's 19800 won for 2GB for 1 month, and includes unlimited olleh wifi (SIM authentication), but you still have to pay 8800 won for the SIM and a 10000-won top-up. Because of the one-time investment, it's a decent rate if you are there for several months and are trying to keep the per-month rate down, but not if you just use it once. Even then, it's a hassle to get. Took me an hour a few months ago (Hongdae location, weekday afternoon).

KT/olleh offers SIM rentals now, and NeoKOSIM and Link Korea both offer similar plans that are all 5/10/30 days (unfortunately nothing for 14-15 days). (NeoKOSIM also has the option of letting you keep the SIM if you get a data-only one, so you can take it all the way through to the plane on your way out of the country.) These guys have pick-up and drop-off points at every airport, and the staff know English much better than any of the "global stores", know what they're doing (it's not "just a SIM" - they have to add your IMEI), and work much more quickly.

Just pay for 30 days (71500 won from any of the 3) and avoid the hassle. I just glanced at all 3 sites, and NeoKOSIM has a 15% off deal for the 10- and 30-day data SIMs.

One additional tip: if your devices are not nano-SIM, assume that they give you a nano-SIM and bring your own adapter. Basically all LTE SIMs are nano nowadays, and nano is today's standard anyways. Adapters can be found for pennies, or as punch-outs from other "3-in-1" SIMs.
