All eSIM regular data plans for countries and regions are unthrottled which means you as a user will always get the best experience and quality of data available based on the network coverage.
Day plans bundles provide 1GB daily unthrottled 5G (where available) per 24 hours and thereafter unlimited data at 512kbs. The 24 hour period is calculated from the point the bundle is first used. Each 24 hour period remaining 1GB of unthrottled data will reset.
