With no daily caps or restrictions, it serves as the premier solution for business professionals and long-term travelers who require a significant, flexible data pool for the duration of their visit.
IMPORTANT: Be cautious of providers advertising "Unlimited Data" without clearly disclosing their limits. Vague wording about slowdowns "beyond their control" that "normalize the next day" usually points to a hidden daily cap — always check directly or review their website for details. Our eSIM includes a clear 3GB daily high-speed data limit. Once reached, speeds reduce to 128kbps for the rest of the day. Your high-speed data refreshes every 24 hours from activation, giving you a fresh 3GB each day for the duration of your prepaid plan.
Ensure your device supports eSIM before buying.

Used this around Korea and never missed a beat. Worked great. Easy installation and when we landed at airport just turned it on. We did install on the day before but this ESim was for more days than we were staying so it was simple to turn on when we landed. Simple and easy to use. Would highly recommend SimCorner.
Deborah D.
Great coverage all throughout South Korea. Encountered an initial hiccup (my own error) with the set up when I first arrived but once I contacted the support team via email they responded immediately & had me up & connected within a few minutes. Would recommend & use again on future travels
