Start with your real data demand. Most roaming mistakes come from underestimating how much navigation, messaging, uploads, and travel streaming actually add up to.

Enter trip length and data assumptions to compare carrier roaming, eSIM, local SIM, and hotspot options.
Tap an example to prefill the calculator with sample values.
Two-week city trip
Moderate daily data use with a typical carrier pass
A common case where eSIM and local SIM pricing often look cheap enough to justify a little setup friction.
Result: Local SIM and eSIM both beat the carrier pass once the trip gets long enough.
Short low-data trip
Convenience can win on a quick trip
Useful for short business travel where setup time matters and total data demand stays low enough that the daily pass is not outrageous.
Result: The convenience premium is smaller on shorter trips, so the carrier pass can stay competitive.
Heavy remote-work travel
Higher usage pushes the comparison hard toward alternative options
This scenario shows why bigger work-and-stream trips often need a dedicated plan instead of relying on the carrier default.
Result: The carrier option gets expensive quickly once the trip is both long and data-heavy.
