A day pass is a flat fee for a day of data, and the question is whether the trip uses enough data to beat the metered rate.
Turn a pass price, trip days, daily data, and a per-megabyte rate into both totals and the cheaper plan.
Travelers buying a roaming pass or a metered data add-on before a trip.
Use the source document or official route that applies to your situation. This guide does not contact another person or verify external information.
Use the daily price of the pass for your destination.
Count the days abroad you need data, not the days of the trip.
Use a week of your normal phone data divided by seven.
Use the per-megabyte rate from your carrier for the same destination.
The App prices both plans with the same data and shows the gap.
Seven days of a $10 pass costs $70. Half a gigabyte a day at 2 cents a megabyte is $71.68, so the pass saves $1.68.
Use your own source and details. The example is not a record about a real person or organization.
Two trips. Both are examples.
Both cases are examples, not records about a real person. The bars show the same numbers the free App computes.
