ZenSim does not provide an unlimited data eSIM for South Korea. Although two plans are named โUnlimited STANDARD,โ they actually grant only 2GB of highโspeed data per day and are capped at 20 days (10 days or 30 days).
If a larger data allowance is needed, you can select one of ZenSimโs fixedโdata options. For example, a 20GB plan is available for 10 days atโฏ$29โฏUSD or 30 days atโฏ$30โฏUSD, while 10GB and 5GB plans are also offered for 10โday or 30โday validity. Fixed data plans can be a more costโeffective choice unless you are an extremely heavy data user.
