常见问题
Is the 200–400MB figure guaranteed?+
No, it is not a guaranteed figure. It is a broad range for a standard-definition call under reasonably good conditions. The real figure depends on the app, how many people are on the line, and the signal at that moment.
Which call app uses the least data?+
We do not have a confirmed comparison across every app on the market, since each one updates its own software over time. For a precise figure, check the help pages of the specific app you use.
If meetings are large group calls, how much data should I set aside?+
Group calls with several video feeds tend to sit toward the higher end of the range in the short answer. We do not add a further precise figure, since it depends on participant count and app. Estimate toward the higher end and add a margin.
Where is the data-saving mode inside call apps?+
The location varies by app and by the version installed — there is no single place that applies to every app. Check that app's own settings menu ahead of your trip.
Does turning off data roaming mid-call save data?+
No — turning off data roaming cuts the whole connection immediately, dropping the call entirely rather than simply using less data. If remaining data is a concern, switch to audio only instead.
If data runs out mid-trip because of daily meetings, what should I do?+
Check the remaining allowance and consider a top-up or upgrading the plan to cover the meetings left on the trip. If you are unsure which option suits, contact the team via LINE at https://lin.ee/skDPoNx (@esimonline) or email at esimonline.asia@gmail.com.
