We set minimum data and validity, and hide daily-capped plans to compare a total trip allowance. You can adjust the filters afterwards.

These are minimum filters, not an exact package size. Daily allowances stay daily; check each plan’s limits and activation terms.

These plans cover South Korea. Coverage in Busan, including indoors, depends on the provider’s network. We have not independently tested city-level signal quality.
