Question 1

Are Roamix tools really free to use?

Accepted Answer

Yes, completely free and no account required. Every calculator and checker in this suite — the Data Calculator, Roaming Savings Calculator, Trip eSIM Planner, and Compatibility Checker — is available to anyone, no login or payment required. We built them to help travelers make confident decisions before they buy.

Question 2

Can I use these tools before creating an account?

Accepted Answer

Yes. All calculations and checks are available instantly without signing up. If you want to save your results or quickly access your purchased eSIM plans, you can create a free Roamix account at any time.

Question 3

Do these tools work for multi-country trips?

Accepted Answer

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 lets you input multi-day trips across multiple countries to estimate savings.

Question 4

How accurate is the data calculator?

Accepted Answer

The Travel Data Calculator uses real-world average data consumption rates for each activity type (maps, messaging, video calls, streaming, etc.) and adds a 20% safety buffer to account for background app usage and real-world variability. It's designed to give you a conservative but realistic estimate so you don't run out of data mid-trip.

Question 5

What does the Compatibility Checker actually check?

Accepted Answer

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 — the two requirements to use any Roamix plan.

Question 6

What is the Trip eSIM Planner for?

Accepted Answer

The Trip eSIM Planner takes your trip details — number of countries, length of stay, usage level, and connectivity needs — and produces a recommended eSIM strategy: whether to use a single-country plan, a regional multi-country plan, or multiple separate eSIMs. It also recommends a data amount range based on your usage profile.

Question 7

Can I use the savings calculator for business travel expense tracking?

Accepted Answer

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 how much switching to Roamix eSIM plans would save. You can calculate per-trip estimates and project annual savings.
