East & Southeast Asia eSIM Guides

Urban coverage here is the best on the site and the borders are what need attention. Mainland China sits behind a firewall, and a Hong Kong or Macau plan routes around it because the traffic breaks out elsewhere, which is the single most useful fact in this region. Across Southeast Asia the multi-country plans are usually better value than three single-country ones, though the plan names rarely tell you which countries are actually included.
