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

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.
How the roaming comparison works
The model starts with total trip data demand from daily usage times trip length. It then compares four purchase paths: daily carrier roaming, eSIM package plus top-ups, local SIM plus top-ups, and a pocket Wi-Fi rental.
Pocket Wi-Fi is treated as a flat rental with setup friction, while eSIM and local SIM costs depend on whether the trip exceeds the included data allowance.
Roaming cost FAQ
Use it to narrow the cheapest lane before checking destination-specific plan details.
Why compare all four options?
Because the cheapest answer changes with trip length and data demand. Carrier passes can be fine on short trips, while longer or heavier-use travel often favors eSIM, local SIM, or hotspot setups.
Why compare included GB on eSIM and local SIM plans?
The calculator needs a way to estimate when the base package runs out. Once you know the trip's total expected usage, it can model how much top-up data would still be required.
Is the top-up pricing exact for every destination?
No. Treat the top-up field as your destination-specific estimate. Different countries and providers price extra data very differently, so this is intentionally editable.
