Frequently Asked Questions about South Korea eSIM

When does my South Korea plan validity start?

Validity begins when your eSIM connects to a supported local carrier network (SK Telecom, KT) in South Korea for the first time. Purchasing or scanning at home will not start the countdown.

Can I make phone calls or receive bank SMS in South Korea?

AeroSIM provides high-speed data. You can keep your primary physical SIM active to receive incoming 2FA verification SMS texts while using AeroSIM for data. VoIP apps (WhatsApp, Telegram, FaceTime, Signal) work flawlessly.
