5 Advantages of eSIMs
eSIM technology brings a range of benefits for travellers and businesses looking for flexible and dependable connectivity.
1. Easy Remote Setup
With eSIMs, setup is a breeze. There’s no need to fiddle with physical SIM cards or make trips to a shop. You can activate an eSIM by simply downloading a profile or scanning a QR code, and your device configures itself in just a few minutes.
"Instead of juggling physical cards, eSIM lets you manage all your connections remotely. It’s like swapping your old CDs for a playlist – instant, digital, flexible and hassle-free." – Cradlepoint.com
For businesses, this remote provisioning translates to major time savings. Instead of dispatching technicians for installations, network updates and carrier changes can be handled in minutes, saving countless hours annually.
2. Store Multiple Plans
Modern eSIM-enabled phones can store between 5 and 10 profiles, with the option to keep one or two active at a time. This makes it easy to separate work and personal profiles or maintain local plans for different countries. Switching between profiles is as simple as navigating through your device’s settings and tapping a few options.
3. Enhanced Security
eSIMs don’t just make life easier – they also add a layer of security. Since they’re embedded directly into your device, there’s no risk of losing or misplacing a physical SIM card. If your device is stolen, you can deactivate the eSIM remotely, preventing unauthorised use. Plus, eSIMs reduce risks like SIM cloning and tampering, making them a safer option overall.
4. Simplified International Travel
Travelling abroad? eSIMs make staying connected effortless. You can activate local or global plans digitally before your trip, skipping the hassle of finding a SIM card shop or dealing with high roaming fees. Providers like ZIM Connections offer coverage in over 200 destinations, letting you purchase and activate plans for seamless connectivity across multiple countries.
For instance, you could set up a local plan for France while still in the UK, ensuring you’re connected the moment you arrive.
5. Saves Space in Devices
By eliminating the need for SIM card slots and trays, eSIMs free up valuable space inside devices. This allows manufacturers to include larger batteries, add new features, or design slimmer, more compact devices – all without sacrificing connectivity. It’s a small change with big implications for device design and functionality.
Disadvantages of eSIMs
While eSIM technology brings convenience, it does come with some hurdles, particularly when it comes to compatibility with devices and carriers.
Limited Support from Carriers and Devices
A significant drawback of eSIMs is that many older or lower-cost devices don’t include the necessary eSIM chip, making activation impossible even if a carrier supports it. For example, certain regional models, like iPhones sold in mainland China, prioritise dual physical SIM slots over eSIM functionality. On top of that, some mobile networks, especially in countries like the US and Australia, restrict eSIM activation to specific, approved devices.
Another barrier arises with carrier-locked devices. If a phone is locked due to financing agreements, its eSIM capabilities may remain restricted until those obligations are met.
These limitations underscore the importance of checking both device and carrier compatibility before opting for an eSIM over a traditional SIM card.
SIM Card Advantages and Disadvantages
While eSIMs bring a modern, digital approach to connectivity, traditional SIM cards remain a reliable and widely accepted option. They offer ease of use, broad compatibility, and straightforward replacement, though they come with certain limitations when compared to their digital counterpart.
Why SIM Cards Are Good
One of the biggest strengths of physical SIM cards is their universal compatibility. Almost every mobile device – whether it’s a simple feature phone or the latest high-end smartphone – comes with a SIM card slot. This means you can switch between devices with ease, without worrying about whether your SIM will work.
Another benefit is the ease of device switching. If you want to move your mobile service to a new phone, all it takes is removing the SIM card from one device and inserting it into another. No technical setup, no waiting for carrier approval – just a quick and simple process.
The simple replacement process is another plus. If your SIM card gets damaged or lost, most mobile networks can provide a replacement quickly and at a low cost. There’s no need for complicated activation steps tied to specific devices.
Finally, traditional SIM cards offer freedom from carrier restrictions. As long as your phone is unlocked, you can use your SIM card with any compatible network. This is especially handy when travelling, as you can easily swap in a local SIM card to avoid high roaming charges, without jumping through hoops to activate it.
Problems with SIM Cards
That said, physical SIM cards do come with their share of challenges that can affect convenience and connectivity.
One of the most common issues is physical handling challenges. Nano-SIM cards, in particular, are tiny and can be easily lost or damaged. Inserting them into a device can sometimes be tricky, and the plastic or metal contacts can wear out or break with repeated use.
For frequent travellers, international travel complications can be a hassle. Buying a local SIM card abroad often means visiting a store in person, filling out paperwork, and potentially dealing with delays. This can leave you temporarily disconnected while you’re on the move.
Another limitation is the lack of multi-network capability. Traditional SIM cards only allow connection to one network at a time, which can be restrictive for users who need access to multiple carriers for better coverage or to save on costs.
Lastly, there’s the issue of vulnerability to loss and theft. If your SIM card is stolen or misplaced, someone else could misuse it, potentially compromising your security. Losing your SIM card while travelling can also leave you without service until you’re able to get a replacement, which is often easier said than done.
