LTE Simcard for Korea - Highspeed Surf and make Phone-Calls

Charges for top ups are exorbitant, 65 Euro for a month, local rates when in country are much cheaper

I didn’t use it

Bought the "Premium Plus" option (100GB fair use) directly on Simcard Korea's homepage, but you can just as well buy on Amazon. It just works. Been super handy to have a Korean phone number while in Korea and also to be able to register it for quarantine. I just specified which date I wanted it activated on the homepage and everything worked when I landed in Seoul. In addition, the data has been flawless and fast. Most importantly though, every time I had a question or inquiry and contacted customer support, they have been quick at answering me, so I felt in totally safe hands. Only hiccup I experienced was when I wanted to extend my package and used the iOS app. It crashed while paying so I used the homepage instead, but apparently both payments went through. No problem though, just sent customer service an e-mail and they quickly cancelled one of the payments and returned the paid amount. As also stated in the listing be aware that phone calls to Korean numbers are free but to make international calls you need to add call credits. Price per minute is fair, so no worries.
