Guest User2026-02-01
The SIM card is amazing! The internet signal is uninterrupted. As soon as I switched networks from Thailand, I had a signal in Korea immediately, even before landing. I highly recommend it! (From someone who's read many reviews). Plus, the T-Money card made the price very affordable.★

These eSIM cards are a great idea. No need to bother with buying physical ones anymore. Have you tried buying and registering a SIM card in the Philippines? Our friends tried, and it took a terribly long time. Overall, if your phone supports eSIM, I highly recommend buying it here. It's less hassle and cheaper.
