Seamless Korea: Your Guide to Avoiding Midnight SIM Card Surprises

On my most recent sojourn to Seoul, I encountered a rather unsettling moment when my mobile data unexpectedly ceased, just as I was guiding my way back through unfamiliar streets late one evening. My seemingly reliable SIM card, I discovered, had an unexpected curfew on data top-ups after 10 PM, leaving me momentarily adrift without my digital companion. This surprising hiccup taught me an invaluable lesson in ensuring seamless connectivity abroad. I've since gathered the essential insights to ensure your own adventures remain perfectly connected, day and night.
