The staff responded to chats quickly, but some didn't check the information before responding, resulting in inaccurate details. The internet signal was excellent and uninterrupted. Highly recommended!

Excellent as always!!! I always buy LGU when I come to Seoul because it's stable and reliable~ I even recommended it to my friends, hehe! I picked it up at the counter at Gate A of Terminal 1, and the lady at the counter spoke a little bit of Chinese! And after removing the SIM card, the pink card is the Tmoney bus card, so you don't need to buy a separate bus card!

It's very fast, powerful, and stable. Easy and hassle-free installation. Say goodbye to constantly removing and inserting your travel SIM card. The price is also reasonable.
