eSIMatrix does not provide any unlimitedโdata eSIM plans for East Asia. Instead, the provider offers fixedโdata options that cover the same region. For example, eSIMatrix sells 20GB plans ranging from 5 days to 30 days, with prices from $33.50 to $41.00 USD, and a 10GB plan for 5 days that costs $20.00 USD. The presence of these fixed data plans means that travelers who need significant data allowances can choose from a range of options and may find the overall cost more favorable than a broad unlimited plan, especially if they are not extremely heavy data users.
