Understanding “Unlimited”: Is It Really Unlimited?
Most unlimited data eSIM Vietnam plans provide a very high “fair usage” threshold (such as 2GB–5GB/day at full speed), after which speeds may be throttled to ensure fair use across the network. For 99% of travelers, this is as close to unlimited as you’ll need—even for video calls, Google Maps, YouTube, Netflix, and social media. You won’t notice any slowdowns unless you download massive files or stream HD videos for hours every day.
