How much does a Europe eSIM cost?
The cheapest option is $4.00 for 1 GB over 7 days. From there plans climb to 20 GB or unlimited, and the unlimited ones run as long as 30 days. Prices change, so instead of pasting a table that goes stale, check the live list on the Europe eSIM page.
Which network does a Europe eSIM use?
Bouygues Telecom supplies the French network, and when you cross a border the eSIM picks up a local partner network automatically. That’s the part that matters: you aren’t paying roaming rates, and you don’t have to switch anything when you step off a train in a new country. 5G comes through where the local network has it; elsewhere it drops to 4G LTE, which is still fine for maps and messaging.
One eSIM for 28 countries, or one per country?
One. If you’re doing a multi-country loop, buying a separate eSIM for each stop means a new QR code, a new profile, and a separate balance to track in every country. A single Europe-wide eSIM is one install and then you forget about it. The only time I’d think twice is if one specific country on your route isn’t in the coverage list — then a small local eSIM just for that leg makes sense.
How much data do you actually need?
Navigation eats about 100 MB a day. Messaging and social media add another 150–200 MB. So a normal week of maps, WhatsApp and the occasional photo upload lands around 2–3 GB total. Video is the exception: an hour of streaming is roughly 1 GB. If your train rides are long and you watch a lot, that changes the math.
When is unlimited data worth it?
Only when you know you’ll stream or tether. If you’re on maps and messaging, unlimited is money you won’t use. But if you’re working remotely and hotspotting a laptop every day, or watching movies across long rail legs, the unlimited 30-day plan is cheaper than buying 20 GB and running out.
Dual-SIM: keep your bank OTPs
A data-only eSIM leaves your physical SIM slot free, so your home number keeps receiving bank verification texts at no extra cost. That’s the setup to use if your bank still sends one-time passwords by SMS.
Arrival and getting around
At Heathrow, the Elizabeth line gets you into central London; the Oyster card or a contactless bank card works on the Tube and buses. In Paris, the RER links Charles de Gaulle to the city, and a Navigo pass covers the métro. The eSIM is active the moment you land, so you can pull up transit directions before you clear passport control.
How to install and activate
- Scan the QR code from your order email under Settings → Cellular → Add eSIM.
- Label the plan so you can tell it apart from your home SIM.
- Turn on data roaming for the eSIM once you land. The plan starts counting from the first connection.
Will my phone work with it?
Any carrier-unlocked phone that supports eSIM will work: iPhone XS or newer, Pixel 3 or newer, and Samsung Galaxy S20 or newer are the common ones. If your phone is locked to a carrier, unlock it first or the install will fail at the QR step.
Frequently Asked Questions About Europe eSIMs
Q1: Which countries are covered?
The 27 EU member states plus the UK: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czechia, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden and the United Kingdom.
Q2: Do I need to register with a passport?
No. Tourist plans don’t ask for a passport upload or ID check under current carrier rules. Local laws can change, so it’s worth a quick check before you go.
Q3: Can I use it as a hotspot?
Yes, hotspot and tethering are enabled on every plan. A laptop or a second phone can share the connection.
Q4: Does it work across borders automatically?
Yes. Cross from France into Germany and the eSIM reattaches to a local partner network on its own — no settings to change.
Q5: When does the plan start counting?
From the first connection to a local network after landing, not from the moment you scan the QR code. Install it at home on Wi-Fi and activate on arrival.
Q6: Can I top up or extend it?
Topping up depends on the plan. The simplest option is to buy a longer plan up front if your dates are fixed; check the live plan list for what’s available.
Q7: What if I run out of data?
Buy a second plan and install it the same way. The first one keeps working until its days or its data run out, whichever comes first.
Q8: Does it work with WhatsApp and FaceTime?
Yes. Calls and messages through WhatsApp, FaceTime, Zalo or Viber run over data, so you don’t need a local number.
Q9: Will I get 5G everywhere?
5G appears where the local network has it — mostly cities. In between you’ll sit on 4G LTE, which handles navigation and messaging without a problem.
Q10: What’s the refund policy?
Refunds depend on whether the plan has been activated. If you buy and don’t install it, you’re usually covered; once it’s active, it’s non-refundable. The full terms are on the product page.
Bottom line
For a multi-country Europe trip, a single data eSIM on Bouygues Telecom with EU partner roaming is the least-fuss option, and 2–3 GB covers a normal week. Pick the size that matches your video habit, install it before you fly, and you’ll have signal the moment you land. See the current plans here.
