NOTE: Check out ISPreview’s recent ‘ Check out ISPreview’s recent ‘ Summary of Mobile Travel eSIMs ‘ for a closer look at what options are available and the various caveats involved. True local breakout, where traffic exits in the country being visited, is said to remain “uncommon” (unless you buy a local eSIM of course). However, the complex network routing of travel eSIMs turns the above expectation on its head, instead showing a much greater performance difference. The download speed distributions on travel eSIMs reveal caps and throttled plans, with one major brand clustering near 6Mbps and a free tier near 0.2Mbps. Instead, if you want the best performance, then we’d say it’s often better to buy a local eSIM for your country of destination (assuming they’re available).
