How to Use the Pocket WiFi vs eSIM Calculator
Getting internet abroad usually comes down to two options: pocket WiFi or an eSIM. A pocket WiFi is a single device shared by the whole group, so the per-person cost drops as more people split the rental fee. An eSIM installs individually on each person's phone, so the total cost scales directly with the number of travelers. This calculator takes your group size, trip length, and the rate for each option to show you the real cost per person.
A pocket WiFi can connect multiple phones and laptops at once, and for groups of four or more it's usually cheaper than eSIMs across the board. The tradeoff is that if the device is lost or its battery dies, the whole group loses internet at once, and everyone has to stay near whoever is carrying it.
An eSIM gives everyone independent internet access, which suits trips where the group splits up often, but the total cost climbs steadily with each added traveler. Solo travelers, pairs, or groups planning to go separate ways often do better with eSIMs, while groups of four or more traveling together usually save more with a shared pocket WiFi.
Frequently Asked Questions
Generally yes. A single pocket WiFi unit's rental fee gets split across the whole group, so the per-person cost drops as your group grows. An eSIM, on the other hand, requires a separate data plan per person, so the total cost scales directly with group size.
eSIM tends to win if you're traveling solo or your group plans to split up often. A pocket WiFi ties everyone to whoever is carrying the device, while an eSIM gives each person independent internet access on their own phone.
