What Are eSIM and Physical SIM Cards?
eSIM and physical SIM cards both serve the same purpose: connecting your device to mobile networks. However, they work in very different ways.
What is an eSIM?
An eSIM, short for embedded SIM, is a digital SIM card built directly into your device’s hardware. Unlike traditional SIM cards, it cannot be removed because it’s part of the device itself. Instead, it’s programmable through software.
"An eSIM is a digital version of the physical SIM card – identifying your device virtually to provide network connection. It’s programmable remotely via software and is built into newer smartphones, meaning you wouldn’t have to go purchase a new SIM card if you wanted to swap phones or wireless carriers." – T‑Mobile
One of the biggest perks of eSIMs, especially for travellers, is the ability to activate them remotely. You can download and set up a data plan for a different country before you even leave home. They also offer added security since they can’t be physically stolen or damaged. Plus, eSIMs save space inside your device, which is a bonus for manufacturers.
Curious about how physical SIM cards differ? Let’s explore.
What is a Physical SIM?
A physical SIM is the removable chip that has been around for years. These come in various sizes – standard, micro, and nano – with nano being the most common today. Physical SIMs are tied to specific carriers, so if you want to switch networks, you’ll need to physically replace the card.
For travellers, this often means buying a local SIM card when you arrive at your destination or picking one up beforehand. While physical SIMs are widely supported by most carriers and devices, having to swap them can be a hassle. There’s also the risk of losing or damaging the card, which adds to the inconvenience.
Device Compatibility
When deciding between eSIM and physical SIM, it’s important to check if your device supports eSIM technology – especially if you travel frequently.
Many newer smartphones, including recent models from iPhone, Samsung Galaxy, and Google Pixel, are eSIM-compatible. To confirm, you can use #06# to check for an EID number, which indicates eSIM support. Alternatively, on iOS devices, go to Settings > Cellular > Add eSIM. On Android, navigate to Settings > Network & Internet > SIMs. If you see an "Add eSIM" option, your device is ready for this technology [14, 15].
Convenience and Ease of Use
When travelling abroad, eSIMs make activating and switching between networks a breeze.
How to Activate Each Option
Activating an eSIM is simple and can be done remotely. Typically, you purchase your eSIM plan online, receive a QR code via email, and then use your device settings to scan it. For instance, on iOS, you’d go to Settings > Cellular > Add Cellular Plan, while on Android, it’s Settings > Network & Internet > SIMs. This means you can set up your eSIM before you even leave home, ensuring you’re connected the moment you arrive at your destination.
In contrast, physical SIMs require a bit more effort. You’ll need to manually insert the SIM into your device’s tray, which usually triggers auto-activation. This often involves buying a local SIM at your destination – perhaps at an airport kiosk or a mobile shop – or bringing one with you in advance. While eSIMs can be set up in the comfort of your home, physical SIMs demand attention once you’ve arrived.
This difference in activation methods highlights the convenience eSIMs bring, especially when it comes to switching networks.
Switching Networks Abroad
For travellers exploring multiple countries, eSIMs offer unparalleled flexibility. Switching networks is as easy as selecting a stored profile on your device. Plus, you can store multiple eSIM profiles, allowing you to switch seamlessly as you cross borders. This is especially handy for travellers navigating through various regions.
On the other hand, physical SIMs require manual swapping, which not only takes more effort but also increases the risk of losing or misplacing the card.
If you have a dual SIM device, you can keep your UK number active on a physical SIM while using an eSIM for local data, helping to cut down on roaming charges. There’s also a security perk with eSIMs: if your phone is lost or stolen, your eSIM profile remains tied to your account rather than a physical card. This means you can quickly reactivate your service on a new device.
Adding to the convenience, nearly 400 mobile network operators now support eSIM technology globally as of 2023, making it easier than ever to access this feature wherever you travel.
Cost and Value for Travellers
Your choice of connectivity can have a noticeable impact on your travel budget, especially if you travel often.
eSIM Pricing
eSIM plans are a cost-effective alternative to traditional roaming fees. Many travel eSIM plans offer several gigabytes of data for around £15–40 per month, which is much cheaper than most roaming charges. For UK travellers, providers like ZIM Connections offer affordable eSIM plans with options for local, regional, and global coverage, allowing you to select the most suitable plan for your travel needs.
The price of eSIM plans varies based on your destination and data requirements. While costs differ between carriers, eSIMs consistently come out cheaper than roaming. Moreover, initial setup fees for eSIMs are usually low, and activation costs are often less than buying a separate physical SIM card.
Physical SIM Pricing
At first glance, physical SIM cards might seem like the cheaper option, as they’re often included for free with new mobile plans. However, the real costs become clear when you factor in roaming fees and the necessity of buying local SIMs while abroad. Traditional roaming charges can be steep, ranging from approximately £4–12 per day or £8–16 per MB of data. For UK travellers, the introduction of EU roaming fees post-Brexit has added to these costs. For example, Vodafone UK charges about £2 per day for EU roaming, with similar fees from EE and O2 on pay-as-you-go plans. Three UK, however, still offers free EU roaming on prepaid SIM cards.
If you’re considering tourist SIM cards in the UK, data-only plans typically range between £10 and £50 for durations of 5 to 30 days. While these may seem affordable, the costs can escalate quickly if you’re travelling to multiple countries and need to purchase a new SIM for each destination.
Cost Comparison
When comparing these options, the savings for frequent travellers become clear. For those travelling to a single destination on a short trip, physical SIM cards might be a reasonable choice if you can secure a good local deal. However, for frequent travellers or those visiting multiple countries, eSIMs often prove to be the better option overall. In fact, 78% of international travellers now prefer eSIMs, primarily because they save money on roaming fees and simplify connectivity management across countries.
The financial difference is even more striking when you compare roaming costs directly. Traditional roaming can cost £4–12 per day, whereas an eSIM plan costs about £15–40 per month. Over a two-week trip, roaming charges could easily exceed £80, while an eSIM plan might cost only £20–30. Additionally, eSIMs spare you the hassle and expense of buying new SIM cards in every destination.
For UK travellers exploring multiple European destinations, eSIMs are particularly advantageous. Regional plans provide seamless connectivity without the added expense of roaming fees, making them an excellent choice for those who want consistent savings and convenience on multi-country trips.

Global Coverage and Availability
Staying connected while travelling hinges on coverage and ease of access. Both eSIMs and physical SIM cards can provide global connectivity, but they operate differently when delivering that coverage.
eSIM Coverage Areas
eSIMs make global connectivity simpler. Leading providers now support over 200 destinations worldwide, making eSIMs a convenient choice for travellers visiting multiple countries. For instance, ZIM Connections offers coverage in more than 200 destinations with local, regional, and global plans, eliminating the hassle of buying separate SIMs for each country.
A standout feature of eSIMs is their ability to switch between networks for better reliability. This is especially useful when travelling through areas with inconsistent network quality. Many travel eSIM providers automatically connect users to the strongest available network, ensuring better signal strength and smoother roaming. For UK travellers, this means uninterrupted connectivity whether you’re navigating a busy city or venturing into remote countryside. The technology seamlessly handles network switching, even in regions with patchy coverage.
In comparison, physical SIM cards face different challenges when it comes to global availability.
Physical SIM Availability
Physical SIM cards are still widely used in regions such as Asia-Pacific, Africa, Latin America, and Eastern Europe. However, they can be harder to obtain when travelling abroad, especially in less accessible locations.
One of the main obstacles is availability. Finding physical SIM cards in remote areas can be tricky, and buying one often involves visiting a local store, overcoming language barriers, and figuring out unfamiliar mobile networks. Some countries even require ID registration to activate a SIM, adding extra complexity for international travellers.
That said, physical SIM cards do have their advantages in certain situations. If you’re staying in a single country for an extended period, they can provide more dependable connections by directly accessing domestic networks. Local carriers often deliver stronger signals and faster data speeds in rural areas, making them a practical option for travellers who won’t be moving between multiple destinations.
Network Reliability
When it comes to network reliability, both eSIMs and physical SIM cards rely on the same carrier networks, meaning their baseline performance is often identical when using the same provider. However, eSIMs have an edge thanks to their flexibility. They can automatically switch to a stronger network when coverage is weak, ensuring a more consistent connection across diverse terrains – an essential feature for international travellers.
On the other hand, physical SIM cards lack this adaptability. If your chosen carrier has poor coverage, you’re stuck with it until you physically replace the SIM.
It’s also worth noting that in countries with strict internet regulations, eSIM services may be restricted or entirely blocked. In such cases, a physical SIM card from a local provider might be your only reliable option for staying connected.
Impact on the Environment
As travellers become more environmentally aware, the choice between eSIMs and physical SIM cards is more than just a tech decision – it’s a chance to reduce your carbon footprint. eSIM technology stands out as a greener option, especially when it comes to cutting plastic waste and lowering emissions.
Reducing Plastic Waste
Physical SIM cards contribute significantly to plastic pollution. Every year, around 4.5 billion SIM cards are issued globally, resulting in over 18,000 tonnes of plastic waste – most of it from non-biodegradable polyvinyl chloride (PVC). These cards also require additional plastic for packaging, all of which ends up in landfills.
eSIMs, on the other hand, completely eliminate the need for physical cards. They use less than 1% of the materials needed to produce traditional SIMs, making them a far cleaner choice. For UK travellers visiting multiple countries, the impact is even more noticeable. Instead of accumulating a pile of plastic SIM cards, a single eSIM provides seamless connectivity across borders without generating any waste.
Lower Carbon Footprint
The environmental toll of traditional SIM cards goes beyond just plastic. The industry is responsible for approximately 180,000 tonnes of CO₂ emissions annually, with carbon output coming from manufacturing, packaging, and global distribution.
eSIMs significantly reduce this impact. They generate 46% fewer CO₂ emissions compared to physical SIM cards. Over its lifecycle, an eSIM produces 123g of CO₂ equivalent, while a traditional SIM card generates 229g of CO₂ equivalent over a typical three-year phone lifespan. By switching to eSIMs, the industry could potentially save 4.4 million tonnes of CO₂ equivalent by 2025.
One key factor is digital activation. With eSIMs, there’s no need for trucks to deliver SIM cards to stores or planes to ship them across countries. This eliminates the emissions tied to the entire physical supply chain. When you activate an eSIM, like those from ZIM Connections, you’re connecting to the world without adding to unnecessary carbon output.
“Traditional SIM cards are quietly harming the planet through plastic waste and emissions. eSIMs cut the clutter – no plastic, no shipping, just greener tech.”
Here’s a quick comparison of the environmental impact of eSIMs versus physical SIM cards:
| Environmental Factor | eSIM | Physical SIM |
|---|---|---|
| Plastic Use | None | High (card and packaging) |
| Energy Consumption | Up to 80% less | High |
| Waste Generation | Minimal (no physical waste) | High (discarded cards and packaging) |
| Material Usage | Less than 1% of physical SIMs | Significant (plastic and metal) |
| CO₂ Emissions | 123g CO₂ equivalent | 229g CO₂ equivalent |
For UK travellers aiming to minimise their environmental impact, eSIMs offer a straightforward way to travel more sustainably. Not only do they provide excellent connectivity, but they also align with the growing need for eco-friendly choices.
