How do I install an Roamix eSIM?

QR code delivered instantly after checkout. Buy before you fly while you still have home connectivity, but do not activate until you land — validity usually starts on first connection to a local network, not at purchase. Your phone must be carrier-unlocked and eSIM-capable.

Can I top up an Roamix South Korea plan?

Roamix offers South Korea plans up to 365 days, so for longer stays it is usually cheaper to buy the longer plan up front than to top up a short one. Top-up availability varies by plan — check the plan detail before you buy if you expect to extend.

The short answer

Roamix has the lowest entry price for South Korea of any provider we track.

Best value on cost per gigabyte is 50 GB / 30 Days at $38.90 ($0.78 per GB).

Is Roamix a good choice for South Korea?

Roamix's catalogue is unusually deep — tens of thousands of plan permutations — and it leans heavily on unlimited day-passes with a daily high-speed allowance that throttles rather than cutting off. That structure suits travellers who want predictable daily cost and don't want to estimate total data up front. Most Roamix inventory is 5G where the local network supports it, which is not true of every competitor at this price point.

Where it wins

✓Unlimited day-passes with throttle-not-cutoff fair use
✓5G on most routes where the local carrier supports it
✓Very granular duration options, from 1 to 365 days

What to watch

!Daily high-speed cap applies before throttling
!Newer brand with a shorter public track record
