Seoul for 10 days. Great speeds, data kept working in the subway. Naver Maps and translator ran non-stop.
Busan and Jeju. Coast was great, island interior a bit weaker. Covered the whole trip though.
QR arrived a minute after payment. Installed at home over Wi-Fi, data switched on automatically at the arrival airport.
Smooth checkout, QR in about two minutes. Not a single dropout during the trip.
Third purchase here. Pay, scan, go — still works every time.
Couldn't find the QR setting on my Samsung at first. Support replied quickly and walked me through it.
