How to get a free eSIM for your next trip

Quick answer

A genuinely free travel eSIM with real data is rare. Most “free eSIM” offers are a profile that installs free but carries no data, or a card-linked trial that renews into a paid plan. Our free 100 MB giveaway is paused for now. Want your own number on eSIM? Many carriers switch your SIM for free or a small fee.

“Free eSIM” is one of the most searched phrases in travel tech, and also one of the most misunderstood. Some offers are genuinely free; many are a free *profile* with no data, or a trial that quietly bills you later. Here's how a travel eSIM actually works, how to tell a real free offer from a hook, how to move your own number to eSIM (often free), and the honest ways to pay less with us.

What “free eSIM” usually means

In short: Free can mean a profile with no data, a card-linked trial, or a genuinely free data bucket.

An eSIM is just a digital SIM profile your phone downloads, there's no plastic and nothing to post. Because the profile itself costs nothing to issue, “free eSIM” can mean a few very different things:

A free profile with no data, you install it for free, then have to buy a plan before it does anything.
A free trial: a small data allowance that's free up front but tied to a card and auto-renews into a paid plan.
A genuinely free data allowance: a fixed bucket (say 100 MB) that's yours with nothing to pay and nothing to cancel.

The only one worth your time is the last. A small free bucket is the perfect way to test coverage, install, and your phone's compatibility before you trust an eSIM with a whole trip.

How a travel eSIM works in 60 seconds

In short: Install at home on Wi-Fi, switch it on when you land, and keep your number on your usual SIM.

You install the profile at home on Wi-Fi by scanning a QR code, it doesn't start any clock. On arrival you set the eSIM as your data line and switch on Data Roaming for it (that just means “use the eSIM's partner network,” never your home carrier). Your physical SIM stays in for calls and texts on your normal number. That's it: data-only, alongside your usual line.

How to spot the catch

In short: No card, no auto-renew and real megabytes: a truly free offer passes all three checks.

Before you trust any “free eSIM,” check three things:

Check	What to look for
Card required?	A truly free bucket needs no card. If it asks for one, it's a trial.
Auto-renew?	Free trials often roll into a paid plan. Look for “no auto-renew.”
Real data included?	“Free eSIM” with 0 MB is just a profile, you still pay for data.

Want a free eSIM for your own number?

In short: Your carrier puts your number on eSIM, often for free, but roaming still costs what it did.

Plenty of people searching “free eSIM” really want their existing number on an eSIM instead of a plastic SIM. That's a job for your home carrier, not a travel eSIM, and it's often free: Odido in the Netherlands says plainly that an eSIM costs nothing, and Telekom in Germany swaps your SIM card for an eSIM profile free of charge. Some carriers charge a small SIM-change fee, so check your carrier's app first. On an iPhone, if your carrier supports it, you can convert your physical SIM to an eSIM without changing phones.

Moving your number to eSIM is often free. It doesn't make data abroad free.

What it won't do is make data abroad free. Your number roams on the same terms and prices as it did on the plastic SIM. For trip data, add a travel eSIM alongside it: your number stays on your home line for calls and texts, and the travel eSIM handles the data.

Questions travelers ask

Is Zwitchy's free eSIM still available?

Not right now. Our free 100 MB eSIM giveaway is paused and may return later. Until then, our 100 MB plans are a low-cost way to try Zwitchy: you pay once, with no contract and no auto-renew.

What's the cheapest way to test an eSIM before a trip?

Pick one of our 100 MB plans for the country you're visiting and install it at home on Wi-Fi, which starts no clock. It's ready the moment you land, with enough for maps and messages, and you can top it up instead of buying a new eSIM.

Can I get a free eSIM from my own carrier?

Often, yes. Many carriers, Odido and Telekom among them, switch your existing SIM to an eSIM for free, while some charge a small SIM-change fee. Ask in your carrier's app. You keep your number, but data abroad still costs whatever your plan charges for roaming.

Is there a free eSIM with a phone number?

A travel eSIM like ours is data-only, so it has no phone number. An eSIM that carries your number comes from your home carrier, and switching your current line over is often free or cheap. Keep both: your number for calls and texts, the travel eSIM for data.

Will it use my phone number or replace my SIM?

No. Travel eSIMs are data-only and install alongside your existing SIM, so your number stays active for calls and texts. You just pick the eSIM for mobile data when you travel.

What can I do with 100 MB?

It's a tester bucket, plenty for maps, messaging, and confirming your install works on a real network before a trip. When you need more, top up the same eSIM in seconds.
