Introduction: Beyond 'Roam Like at Home'
You’ve booked your flights from Otopeni, your bags are nearly packed, and you’re dreaming of wandering through Rome or grabbing a coffee in London. As a Romanian traveler, you’re probably thinking, “I’ve got ‘Roam Like at Home,’ so my phone is sorted.” I’ve been there. But what many of us discover, often at the worst possible moment, is that our domestic plan has its limits. The promise of free EU roaming can quickly evaporate due to 'fair usage' policies, and since Brexit, the UK is a whole different story. This is where finding the best eSIM for EU travel becomes not just a convenience, but a travel essential. It’s the modern solution that puts you back in control, ensuring you have data the second you land without hunting for Wi-Fi or worrying about surprise bills. For trips that include London, a reliable UK prepaid eSIM is absolutely non-negotiable.
The Reality of Roaming in the EU for Romanians
The “Roam Like at Home” regulation was a game-changer for travel within the European Union. It meant we could use our Romanian data, call, and text allowances in other EU countries without extra charges. However, it was designed for short trips, not for extended stays or heavy data users. This is where the fine print, the part we all tend to skip, comes into play.
Understanding 'Fair Usage Policies'
Your Romanian mobile operator (like Orange, Vodafone, or Telekom) implements a Fair Usage Policy (FUP) to prevent permanent roaming. Essentially, if you spend more time abroad than at home over a four-month period, or consume more data abroad than domestically, they can start applying surcharges. For a week-long holiday, you’re usually fine. But for a month-long backpacking trip, studying abroad, or working as a digital nomad, you could easily breach this policy. The surcharges, while capped by the EU, can still add up unexpectedly.
The UK Complication: A Post-Brexit World
Here’s the biggest catch for many travelers: the United Kingdom is no longer part of the EU. This means UK is not included in the “Roam Like at Home” agreement. Using your Romanian SIM in England, Scotland, Wales, or Northern Ireland will likely result in significant roaming charges, just like traveling to Turkey or Egypt. The cost of checking Google Maps from Heathrow or posting a story from Edinburgh can be shocking if you’re not prepared. This single reason makes a dedicated travel eSIM a smart financial decision.
Why an eSIM is Your Best Travel Companion
So, if your domestic plan has its limits, what’s the alternative? For years, travelers would hunt for a local physical SIM card upon arrival. This often involved language barriers, complicated registration processes, and swapping out your tiny home SIM (and hoping you don't lose it). Today, a digital SIM card Europe, or eSIM, eliminates all that hassle.
What Exactly is an eSIM?
An eSIM (embedded SIM) is a digital SIM card that is built into your smartphone. Instead of a physical chip, it’s a rewritable chip that lets you download and install a data plan from a provider like Cellesim. You can store multiple eSIM profiles on one phone and switch between them, making it incredibly flexible for international travel.
The Clear Advantages of an eSIM for EU Travel:
- Instant Connectivity: You can purchase and install your eSIM data plan Europe from your home in Bucharest or Cluj before you even leave. Activate it upon landing, and you’re online instantly. No more desperate searches for airport Wi-Fi to call an Uber.
- Cost-Effective: Prepaid eSIM plans are almost always cheaper than roaming. You pay for a set amount of data for a specific duration. There are no hidden fees or surprise bills waiting for you back home. You can even use our tool to estimate how much data you'll actually need for your trip to avoid overpaying.
- Keep Your Romanian Number: Because the eSIM handles your data, your physical SIM slot remains free for your Romanian SIM. This means you can still receive calls and SMS messages on your primary number while using the eSIM for affordable local data.
- Enhanced Security: Buying a SIM card from a random street kiosk can be risky. An eSIM from a reputable provider is purchased and activated securely through official channels, protecting your personal information.
Choosing the Right eSIM Data Plan for Your Trip
Not all trips are the same, and neither are eSIM plans. Finding the perfect fit means considering a few key factors. The goal is to pay only for what you need, whether you're on a quick city break to Paris or a multi-country tour.
Step 1: Check Your Device Compatibility
First things first, you need to ensure your phone supports eSIM technology. Most smartphones released in the last few years do, including iPhones from the XR/XS onwards, Samsung Galaxy S20 series and later, and Google Pixel 3 and newer models. The easiest way to be certain is to check if your phone is eSIM-ready using a compatibility list.
Step 2: Define Your Coverage Needs
Where are you going? This is the most important question.
- Single Country: If you're only visiting one country, say for a week in Rome, a country-specific eSIM plan for Italy will be the most cost-effective option. It gives you dedicated coverage on local networks for the best possible speeds.
- Multiple EU Countries: For a trip that spans Germany, Austria, and the Czech Republic, a regional Europe eSIM is perfect. It provides seamless connectivity across dozens of countries on a single plan, so you don’t have to worry about your connection dropping as you cross borders.
- EU + UK Trips: This is a common itinerary for Romanians. It’s crucial to select a plan that explicitly includes both the EU and the UK. Cellesim offers specific bundles designed for this exact scenario, ensuring you’re covered from the canals of Amsterdam to the Tower of London.
Step 3: Estimate Your Data Usage
How much data do you really need? Be realistic about your habits.
- Light User (1-3 GB/week): You primarily use data for maps, messaging (WhatsApp, iMessage), and light browsing. You connect to hotel Wi-Fi when possible.
- Medium User (5-10 GB/week): You’re active on social media, stream some music, watch a few short videos, and use maps extensively. This is the most common traveler profile.
- Heavy User (20 GB+): You work remotely, attend video calls, stream movies, or travel with family who will use your hotspot. An unlimited or large data plan is your best bet.
Getting Started: Your Simple 3-Step eSIM Activation
One of the biggest myths about eSIMs is that they are complicated. The reality is much simpler and can be done in minutes from your couch. The process is straightforward and designed for travelers, not tech experts.
1. Purchase Your Plan
Choose your destination and data package on the Cellesim website. After a secure checkout, a QR code will be delivered instantly to your email. There's no waiting for a physical card to be shipped.
2. Scan and Install
Before you travel, connect to Wi-Fi at home. Go to your phone’s settings (Cellular/Mobile Data > Add eSIM/Data Plan) and scan the QR code from your email. Your phone will guide you through a few simple prompts to install the eSIM profile. For a detailed walkthrough, you can always consult our interactive setup guide.
3. Activate Upon Arrival
Once your plane lands at your destination, simply go back into your phone’s settings, turn on your new eSIM line, and enable data roaming for it.

You get the benefit of connecting to premium local networks because of how our network partnerships work, giving you faster speeds than typical roaming.
Conclusion: Travel Smarter, Not Harder
As a Romanian traveling through Europe and the UK, relying solely on your domestic mobile plan is a gamble. Fair usage policies can lead to throttled speeds or extra charges, and post-Brexit Britain is a guaranteed roaming trap. The best eSIM for EU travel is one that gives you freedom, predictability, and peace of mind. It’s about landing in a new country and knowing your connection is already sorted, allowing you to focus on the adventure ahead. By taking a few minutes to set up an international eSIM before you leave, you’re not just buying data; you’re buying a smoother, more connected, and stress-free travel experience.
