Overall Ratings & Reviews South Korea 4G Pocket WiFi Rental (Airport Pickup) with Lotte Duty Free Discount Voucher

When arriving at the LGU+ counter in Incheon, the officer looked confused when shown this booking voucher. It took quite a long time to get this device. I didn't get the Lotte Duty Free voucher. The officer there didn't explain anything about this voucher either, and I forgot to ask because I was already being rushed by the group waiting to leave. In terms of signal, it was really good, the signal was still good up to the top of the mountain. It's just that the battery runs out quickly, so I have to connect to a power bank frequently.
