Snap inspection. Do you know where your SIM extraction tool is right now?

We didn’t think so.

While pretty much every aspect of smartphones has become slicker and more user-friendly over the years, the process of changing a SIM card has only got trickier. In fact, you can’t even do it without using a tiny tool that you’ve almost certainly lost.

Fortunately, change is just around the corner. The humble SIM card is on the brink of being replaced by the eSIM. Here’s why that’s the best news you’ll read today.

An eSIM – which stands for Electronic Subscriber Identity Module – is a programmable alternative to a standard SIM. That means it lets you make changes through software rather than hardware.

Buying a new plan or making changes to your existing plan is as simple as going online and scanning a QR code.

Besides never having to fish out your SIM extraction tool again, the major advantage of an eSIM is that it lets you enjoy global data roaming. Once you’re set up, you can go anywhere you like without having to contact your operator or pore through T&Cs.

But the benefits don’t stop there. An eSIM is also infinitely more secure than a traditional SIM, which is surprisingly vulnerable to simjacking, SIM cloning, SIM swaps, and other nefarious acts of cyber assault.

That’s because eSIMs won’t let you use them without entering an activation code. Your personal details are locked down tight unless you give explicit permission for them to be shared.

At this point, you’re probably wondering how to get your hands on this miracle technology. It’s surprisingly easy, with a huge number of telcos already in the space and countless more set to join them over the coming months and years.

You can take your pick from no-frills offerings like Flexiroam, which offers little in the way of customer support but a huge amount of value, or comprehensive and well-supported options like Airalo, which charges a bit more for a slicker customer experience.

Or you could go for a fantastic all-rounder like Nomad, which offers fantastic value and superb performance.

One day, you might even be able to pick up an eSIM contract with Starlink, the sci-fi satellite network that beams information around the world using space lasers.
