How to Unlock an iPhone for All Networks: A Traveler’s Guide
Getting your iPhone unlocked for any network is a straightforward process, but it starts with a few key checks. The only reliable and safe way to do it is by…
The best data-only SIM plans give you a no-fuss way to get affordable mobile internet when you’re abroad. Most of the time, this comes in the form of an eSIM you can install in seconds. These plans cut out the extras you probably don’t need, like calls and texts, and focus on one thing: giving you fast, reliable data. That means you can use all your favorite apps for maps, messaging, and social media without the dread of a surprise roaming bill when you get home.
Welcome to the essential guide for any modern traveler who just wants reliable and affordable internet overseas. If you’ve ever returned from a trip to a phone bill that made your eyes water, you know the sting of traditional roaming fees all too well. Thankfully, the days of paying steep daily charges or frantically searching for a local SIM card shop the moment you land are over.
The smart way to stay connected now is with data-only plans, especially those that use eSIM technology. It’s a complete game-changer, whether you’re a digital nomad exploring Southeast Asia, a truck driver crossing borders, or on a two-week holiday in Europe. By stripping away everything but the data, these plans deliver exactly what you need to navigate and share your journey.
So, what exactly are data-only SIM and eSIM plans? Think of them as straightforward mobile plans that give you internet access without a traditional phone number for calls and texts. This is perfect for how most of us travel today, using apps like WhatsApp, Google Maps, and FaceTime to get around and keep in touch.
Here’s why this approach works so well for travelers:
This guide will give you a clear, practical framework for choosing the right data-only plan for any trip. We’re focused on flexible options that put you in control of your spending, making your travels that much smoother and more predictable.
A data-only eSIM lets you connect to local mobile networks just like a physical SIM card, but without needing to swap anything. It’s simply a digital profile you download to your phone, giving you instant internet in over 150 destinations.
Choosing the right plan often boils down to one key question: physical SIM card or digital eSIM? Each has its purpose, but for the modern traveler, the differences really matter.
| Feature | Physical SIM Card | Travel eSIM |
|---|---|---|
| Activation | You have to find a shop, buy the card, and physically swap it into your phone. | Instant activation by scanning a QR code, usually done before you even leave. |
| Flexibility | One SIM, one plan. Changing countries often means changing SIMs. | You can store multiple eSIM plans on one device and switch between them with a tap. |
| Security | Can be lost, stolen, or damaged, leaving you without service. | It can’t be physically lost or stolen because it’s stored securely on your device. |
| Availability | You’re at the mercy of shop opening hours and whether they have any in stock. | Buy and install anytime, anywhere you have an internet connection. |
The way we travel and stay connected has completely changed. Not long ago, getting a plan for your trip abroad meant a package deal: some calls, some texts, and a tiny bit of data. Today, that model just feels outdated. Travelers now prioritize one thing above all else—fast, reliable internet.
This isn’t a random shift. It’s a direct result of how we use our phones when we’re away from home. We rely on Google Maps to navigate winding city streets, use WhatsApp to video call family back home, and post our adventures on Instagram in real-time. For these modern travel essentials, old-school phone calls and SMS texts have taken a back seat.
These days, almost all communication happens over the internet. Apps like FaceTime, Telegram, and Messenger have made international calls and texts practically free as long as you have a decent data connection. This change in behavior makes a strong argument for data-only plans, which let you ditch the expensive extras you probably won’t use anyway.
This trend is also getting a boost from the popularity of unlocked, SIM-free phones. A recent CCS Insight survey highlights this perfectly, showing that 42% of UK mobile users are now on SIM-only plans—a big jump from 35% in 2019. It’s no coincidence that this lines up with the rise in SIM-free phone sales, which now make up a third of all new handsets shipped.
For any traveler, the benefits of going data-centric are hard to ignore. Instead of worrying about eye-watering roaming charges from your provider back home, you get a straightforward, prepaid package that puts you in control.
Think about it this way:
This move towards flexible, data-first solutions gives you complete freedom. You’re not locked into a rigid contract; you can pick a plan that fits your trip perfectly, whether it’s a weekend getaway to Europe or a month-long backpacking adventure across Asia.
By focusing purely on data, you align your spending with your actual needs. It’s the logical choice for anyone who relies on internet-based apps to navigate, communicate, and share their journey.
The technology that makes all of this so seamless is the eSIM, or embedded SIM. It’s a digital SIM that lets you activate a mobile data plan without fumbling with a physical card. If you’re new to the concept, you can explore our guide explaining what an eSIM is.
With a provider like TapSim, you can buy and install an eSIM before you even pack your bags. A little prep work means you can land, switch on your phone, and be connected instantly. It’s this blend of cost-effectiveness and sheer convenience that is making data-only plans the new go-to for savvy globetrotters.
Finding the best data-only SIM plan isn’t just about grabbing the cheapest deal you see. The right plan should feel like it was made for your trip, fitting your travel style, itinerary, and data habits without any fuss. Get this right, and you’ll enjoy smooth connectivity without overspending or, worse, running out of data when you need it most.
To nail down the perfect option, you need to think about a few key things. How much data do you genuinely need? How long does the plan need to last? And where in the world are you headed? A solo backpacker hopping across Southeast Asia has completely different needs from a family on a week-long holiday in Spain.
This simple flowchart helps break down that first big decision you’ll need to make.
As you can see, having an unlocked, eSIM-compatible phone really opens up a world of convenient and flexible options for staying connected abroad.
First things first, let’s figure out how much data you’ll actually get through. It’s surprisingly easy to underestimate this, so be honest about your typical online activities. Are you a light user who just needs maps and the occasional message, or are you planning to stream videos and work from a beachfront cafe?
Here’s a quick breakdown to help you gauge your usage:
Always double-check if a plan allows hotspotting if you plan to share your connection with a laptop or another traveler. With TapSim, most plans include this feature, giving you that extra bit of flexibility on the road.
Before you commit to a plan, it’s wise to weigh up a few essential factors. This table breaks down what you should be looking for to ensure you get the best value and performance for your specific needs.
| Evaluation Criterion | What to Consider | Pro Traveler Tip |
|---|---|---|
| Data Amount | How much data is included? Is it enough for your planned activities (maps, streaming, work)? | It’s often cheaper to buy a slightly larger data bundle upfront than to pay for expensive top-ups later. |
| Plan Validity | How many days does the plan last? Does it cover your entire trip, including travel days? | Look for plans that activate upon connecting to a network at your destination, not on purchase. This maximizes your usage time. |
| Coverage Area | Does the plan cover a single country, a specific region (e.g., Europe), or is it global? | For multi-country trips, a regional eSIM is almost always more convenient and cost-effective than buying local SIMs at each stop. |
| Hotspotting | Can you share your data connection with other devices like a laptop or a tablet? | Not all plans support tethering. If this is a must-have for you, confirm it’s enabled before you buy. |
| Network Quality | Which local carriers does the provider partner with? Are they known for good speeds and coverage? | Check reviews for the specific country you’re visiting to get real-world feedback on network performance. |
Thinking through these points will help you move beyond just the price tag and find a data plan that genuinely works for you while you’re away.
Next up, think about the geography of your trip. Data-only eSIM providers usually have three types of plans, and picking the right one is crucial for getting the best value.
Finally, don’t overlook the plan’s validity period. A 30 GB plan that expires in just seven days is no good if your trip is two weeks long. Always make sure the plan’s duration comfortably covers your entire stay.
Also, think about the activation process. Modern eSIMs have the massive advantage of instant activation. TapSim, for example, lets you install your eSIM by scanning a QR code before you even leave home. The plan only kicks in once you connect to a network at your destination, meaning the clock on your data validity starts exactly when your trip does.

When you’re sorting out your travel plans, figuring out how you’ll stay connected is as vital as booking your flights. The decision usually boils down to two options: a classic physical SIM card or a modern eSIM. While both will get you online, the experience they provide couldn’t be more different, especially when you’re on the move.
Picture this: you’ve just touched down after a long-haul flight. If you’re using a physical SIM, your first job is to hunt down a local mobile shop, wrestle with potential language barriers, and physically swap that tiny chip in your phone. It’s a hassle that can eat into precious travel time and add a layer of stress right at the beginning of your trip.
Now, imagine that same landing but with an eSIM. You simply switch your phone off airplane mode, and you’re instantly connected to a local network. Why? Because you bought and set up your data plan before you even left home. This immediate, seamless connection is exactly why so many travelers are making the switch.
The biggest difference between the two really comes down to pure convenience. A physical SIM requires a hands-on approach that feels increasingly out of place today. You have to find a vendor, which can be a real pain if you land late at night or in a less-traveled area.
An eSIM, being entirely digital, cuts out that physical hunt completely.
The ability to land and immediately call a taxi, pull up your hotel booking, or let family know you’ve arrived is a massive relief. eSIMs make this happen without any of the old-school SIM card hassle.
Beyond that initial convenience, eSIMs bring some serious benefits in security and flexibility. A physical SIM is a tiny, loose item that’s all too easy to lose, damage, or even have stolen. If that happens, your connection is gone, and you might lose your local number until you can sort a replacement.
Because an eSIM is built right into your phone’s hardware, it can’t be physically removed or misplaced. This simple fact makes it a far more secure choice for travelers. If your phone gets lost or stolen, the eSIM can’t be popped out and used in another device, adding a welcome layer of protection.
This digital setup also opens up a level of adaptability that physical SIMs just can’t offer.
| Aspect | Physical SIM Card | Modern eSIM |
|---|---|---|
| Security | Can be lost, stolen, or damaged, resulting in a loss of service. | Embedded in your phone, so it can’t be physically lost or stolen. |
| Flexibility | One plan per card. A new country often means finding and buying a new SIM. | Store multiple plans on one phone and easily switch between them as you travel. |
| Acquisition | Requires tracking down a physical shop with set opening hours. | Bought online 24/7 and installed in minutes via a QR code or app. |
This comparison makes it clear why the best data-only SIM plans are now overwhelmingly delivered via eSIM. They’re simply built for the modern traveler who values efficiency, security, and being in control.
For most international travelers with a compatible phone, an eSIM is the obvious choice. It delivers a smooth, secure, and flexible way to get online abroad. Being able to sort out your connectivity in advance removes a major headache on arrival, letting you focus on enjoying your trip from the second you land.
Physical SIMs still have their place, particularly for people with older phones, but the tide has definitely turned. The sheer simplicity of buying a plan online and activating it with a quick scan makes eSIMs the go-to for reliable data anywhere in the world. If you’re looking for the most efficient way to stay connected, an eSIM is undoubtedly the way forward. You can check for available eSIMs and see just how easy it is to get started on TapSim.net.
Let’s be honest, picking a data plan feels like a constant tug-of-war between getting enough data and not overpaying. It’s so tempting to just grab an ‘unlimited’ plan and call it a day, thinking it’s the safest option. But from a traveler’s perspective, ‘unlimited’ rarely offers the best value for your money.
The real goal is to find that perfect balance—a plan with a data allowance that covers everything you need, but without the hefty price tag that unlimited packages often carry. It’s all about sidestepping the classic traveler’s dilemma: either paying for data you’ll never touch or, even worse, running out of connection just when you need it most.
That word, ‘unlimited’, can be a bit of a marketing gimmick. Dig into the small print of many plans, and you’ll often find a ‘fair use policy’. This means that after you use a certain amount of data, the provider can throttle your speeds, slowing you down to a crawl. For most of us, a well-chosen mid-range plan is a much smarter move, offering a better cost per gigabyte and a more reliable connection speed.
The numbers don’t lie. A recent market analysis of mobile contracts showed that people on unlimited data plans pay the highest average price—a steep £38.91 per month. That’s a whole 13% more than other packages. Compare that to plans in the 60GB to 80GB range, which hit the value sweet spot at just £17.86 monthly. That’s less than half the price of the ‘unlimited’ deals. If you’re curious, you can read more about these mobile statistics and see the trends for yourself.
It’s pretty clear: focusing on a specific data allowance, rather than being lured by the promise of endless data, is the savvier financial decision.
So, how do you figure out exactly how much data you’ll need? It really comes down to thinking about how you use your phone when you’re away. Will you just be checking maps and sending a few messages, or are you planning to stream films and jump on video calls for work?
A great rule of thumb is to pick a plan that offers slightly more data than you think you’ll use. This gives you a nice buffer for any unexpected data-heavy activities without bumping you into a much more expensive tier.
Here are a few common traveler profiles to help you find your match:
The real game-changer is flexibility. The best data-only plans let you top up easily and affordably if you start to run low. This puts you in control, allowing you to add more data only when you truly need it, which is far more cost-effective than buying a massive bundle upfront ‘just in case’.
With TapSim, for instance, you can choose a plan that’s tailored to your trip’s length and your expected data habits. And if things change and you find yourself burning through data faster than planned, topping up is straightforward. It’s a simple way to make sure you’re always connected without breaking the bank.
It’s an all-too-common travel story. You land in a new country, fire up your phone to navigate to your hotel, and maybe make a quick video call home. Before you know it, you’ve got that dreaded text: you’re almost out of data.
To pick the right data-only plan and avoid those frustrating mid-trip top-ups, you first need a solid grasp of where your data actually goes. It’s not always what you think.
Many travelers don’t realize just how much more data-hungry modern apps have become, especially with 5G speeds making high-quality streaming the norm. This trend is only heading in one direction. Some forecasts predict the average data use per smartphone could leap by 50% between 2022 and 2025.
What this means for you is simple: a data package that seemed generous on your last holiday might not cut it this time around.
Let’s break down what some typical travel activities really cost in terms of data. These are just estimates, of course – app updates and quality settings can change the numbers – but they give you a realistic baseline.
It’s clear that some activities, particularly anything involving video, can drain your allowance in no time. That’s why knowing your own habits is the most important step.
So, how do you avoid running dry? Start by thinking about your travel style. Are you a light user who just needs maps and the odd message, or are you a heavy user who plans to work remotely and stream films in the evening?
Your data needs are unique to your journey. By understanding where your gigabytes go, you can choose a plan with confidence, ensuring you stay connected for your entire trip without overspending.
Let’s put it into practice. Imagine a day where you navigate for two hours, stream music for an hour, and make a 30-minute video call. You’ve already used around 350 MB. Throw in some social media and web browsing, and you could easily hit 1 GB in a single day. If you’re not sure where to start, our guide can help you figure out questions like, is 1 GB of data enough for a 7-day trip?.
Once you’re mindful of these numbers, you can choose a plan from TapSim that truly fits your needs, giving you one less thing to worry about on your travels.
Stepping into the world of travel data plans and eSIMs for the first time? It’s completely normal to have a few questions. Getting the right information upfront makes choosing a plan a breeze. Here are a few of the most common queries we hear from fellow travelers.
Yes, you absolutely can, and this is one of the best things about using a data-only eSIM abroad. Your primary SIM card (whether it’s a physical one or another eSIM) stays active in your phone, which means your normal phone number remains live.
You just tell your phone to use the travel eSIM for all mobile data. This clever dual-SIM setup lets you tap into cheap local data for things like navigating with Google Maps or browsing online, while still being able to receive calls and texts on your home number. It’s the best of both worlds.
The good news is that most phones made in the last few years are already eSIM-ready. This covers iPhones from the XR and XS models onwards, plus a huge range of popular Android phones from Google, Samsung, and other big names.
But the fastest way to know for sure is to take a quick peek in your phone’s settings.
Settings > Mobile Data. If you see an option like “Add eSIM” or “Add Data Plan,” you’re all set.Settings > Connections > SIM Manager. The presence of an “Add eSIM” button means you’re good to go.A quick check before you buy gives you total peace of mind. TapSim has a simple compatibility checker on its website that will give you a definite answer in seconds.
Running low on data mid-adventure isn’t the drama it used to be. Most modern eSIM providers have made it incredibly simple to top up your plan right from your phone. Rather than having to buy a brand-new plan from scratch, you can just add more data to the one you’re already using.
This flexibility is a massive advantage. You can start with a smaller, cheaper plan and only add more data if you find you need it. With TapSim, for example, topping up is a quick and painless process designed to get you back online in minutes.
Ready to travel without the connectivity headache? TapSim offers fair, fast, and honest eSIMs for over 150 destinations, so you can land and get online in minutes.
