Frequently asked questions
Are Roamix tools really free to use?

Every tool in this suite, including the Data Calculator, Roaming Savings Calculator, Trip eSIM Planner, and Compatibility Checker, is available to anyone with no login or payment needed. We built these tools to help travelers make confident eSIM decisions before they buy.
Can I use these tools before creating an account?

Can I use the Roamix tools to plan a multi-country trip?
Yes. The Trip eSIM Planner specifically handles multi-country and regional travel scenarios, helping you decide between country-specific plans and regional eSIM options. The Roaming Savings Calculator also supports multi-day trips across multiple countries so you can estimate total savings for your entire itinerary.
How accurate is the data calculator?
The Travel Data Calculator uses real-world average data consumption rates for each activity type, including maps, messaging, video calls, and streaming. It adds a 20% safety buffer to account for background app usage and real-world variability. The result is a conservative but realistic estimate designed to ensure you do not run out of data mid-trip.
What does the Roamix eSIM Compatibility Checker do?
The Compatibility Checker reads your device's browser and hardware signals to identify your phone model and estimate whether it supports eSIM. It also walks you through manual steps to verify eSIM support and carrier-unlock status in your phone's settings, which are the two requirements to use any Roamix eSIM plan.
What does the Roamix Trip eSIM Planner do?
The Trip eSIM Planner takes your trip details, including number of countries, length of stay, and usage level, and produces a recommended eSIM strategy. It advises whether to use a country plan, a regional multi-country plan, or separate eSIMs. It also recommends a data amount range based on your travel profile.
Can I use the savings calculator for business travel expense tracking?
Yes. The Roaming Savings Calculator is particularly useful for frequent business travelers and travel managers who want to estimate monthly or quarterly roaming spend and evaluate potential savings from switching to Roamix eSIM plans. You can calculate per-trip estimates and project annual savings for expense reporting or budget planning.
