Your Trip, Not a Month
We Ask How Many Days You Are Travelling and Count Exactly That Many. Other Calculators Work in Whole Months, So a Five-Day Trip Comes Back With Six Times the Data

Six Sliders and Not One Technical Question. Say Where You Are Going, How Long For, and What a Normal Day on Your Phone Looks Like. We Base Every Hour on What the Apps Really Use, Count Everyone Travelling With You, and Pick the Right eSIM for Your Trip — at the Price You Would Pay Today
We Ask How Many Days You Are Travelling and Count Exactly That Many. Other Calculators Work in Whole Months, So a Five-Day Trip Comes Back With Six Times the Data
We Count Every Hour You Enter Against the eSIM. We Never Take Off a Share for Hotel Wi-Fi You Might Not Get, and Never Add a Margin You Cannot See — the Number Is What You Described
Nobody Knows What Resolution They Watch Video At. So We Ask Only What You Do Know — How Many Hours a Day You Spend on Each Thing — and Leave the Maths to Us
You Do Not Just Get a Number in Gigabytes. Pick a Destination and We Show You the eSIMs That Cover It, With the Price. Everywhere Else You Are Left to Work That Out Yourself
You Already Tell People Where to Go — Now Get Paid for it. Send Someone Our Way and Every Purchase They Make for a Full Year After That First Click Pays You in Cash. Creators, Travel Agencies or the Friend Everyone Asks: the Rates Below Are What You Actually Get, from the Very First Payout
On a Normal Holiday — Maps All Day, Photos, Messages, a Bit of Video in the Evening — Most People Use Somewhere Between 5 and 15 GB a Week. Stream Every Night in the Hotel, or Work Off a Laptop on the Hotspot, and It Climbs Into the Tens of Gigabytes. That Is Too Wide a Range to Guess At, Which Is Why the Calculator Above Asks About Your Day Instead
Most of Them Never Ask How Long You Are Travelling — They Count a Whole Month Whether You Are Away Five Days or Fifty. Then There Are the Rates Themselves: One Well-Known Calculator Puts an Hour of Social Media Above an Hour of Video Streaming, Which Cannot Be Right
No, and That Is Deliberate. We Cannot Know Whether the Hotel Wi-Fi Works, Whether the Café Has Any, or Whether You Will Spend the Afternoon on a Train — So Every Hour You Enter Counts Against the eSIM. If We Quietly Took Half Your Trip Off, We Would Sell You a Smaller Plan Than You Actually Need. If You Know Your Evenings Are on Wi-Fi, Set the Video Slider to Only What You Will Watch on Mobile Data
Usually Yes. Nobody Has an Average Week — One Rainy Afternoon, a Delayed Flight or a Film You Had Not Planned and You Are Over the Estimate. We Do Not Add a Buffer of Our Own, Which Is Why the Number You See Is Exactly What You Entered. If the Trip Matters, Take the Next Size Up — and if That Still Runs Out, You Just Top Up
You Top Up and Carry On. It Takes a Couple of Taps in Your Account — Nothing to Swap, Nothing to Reinstall, the Same eSIM and the Same Number. Which Is Why You Do Not Need to Overshoot: Running Out Is a Few Minutes of Work, Not a Ruined Trip
It Depends More on How Long You Are Away Than on How Much Data You Use. A Week of Unlimited Is Cheap, a Month Is Not — So the Point Where It Beats a Sized Plan Moves With the Length of the Trip. We Do Not Guess Where That Is: We Compare Both Real Prices for Your Destination and Recommend the Cheaper One
Yes, Through the Phone Hotspot. Set the Sliders to One Person’s Day, Then Click How Many Are Joining — We Work Out the Rest. Watch the Laptop Though: It Pulls Full Desktop Pages and Syncs Everything, So It Uses Far More Than a Phone. That Is Why It Has a Slider of Its Own
We Take the per-Hour Rates From Published Figures or the Median of Independent Measurements, Set to What People Normally Do — Video Is Counted at 720p, Music at the Quality Every App Defaults To. Watch Everything at the Highest Resolution and You Will Use More; at the Lowest, Less. Treat the Result as a Well-Founded Estimate, Not a Promise
This eSIM Data Usage Calculator Answers the Question Every Traveller Asks Before They Fly: How Much Mobile Data Will I Need Abroad? It Counts With Real per-App Rates — Maps, Social Feeds, Video Streaming, the Hotspot — and Matches Your Estimate Against the Prepaid Data Plans We Sell for 217 Destinations. It Picks the eSIM That Covers It and Shows Today’s Price, With No Roaming Charges
