Jetpac

Jetpac offers straightforward, prepaid data packages for Korea travelers, with rates starting at $1.00 per gigabyte for 4-day passes. The company partners directly with SK Telecom and KT, Korea's largest carriers, so you get reliable 4G LTE and 5G coverage across Seoul and regional cities without hunting for local SIM cards. Activation happens instantly through their app once you land.

This works best for short trips where you know roughly how much data you'll burn. Since pricing is transparent and fixed by plan size rather than daily rates, budget travelers appreciate knowing the exact cost upfront. The 4-day window is tighter than some competitors' 7-day minimums, making it ideal for weekend getaways to Korea.
