What is an eSIM?

An eSIM (or embedded SIM) is a chip in your phone that can act like a physical SIM card. Rather than inserting a new SIM card to join a new mobile network, you can instead download an eSIM profile. No need to physically swap cards – it’s all done electronically.

Sometimes eSIMs are called by their technical name: embedded universal integrated circuit card, or eUICC. But it’s the same thing – a chip that gives access to a mobile network.

How does eSIM work – the basics

An eSIM works almost exactly like a regular SIM card – only it’s embedded into your phone and can’t be removed. So if you want an iPhone 14 eSIM plan for example, you don’t need to physically swap out SIM cards to switch to a new network when traveling abroad, you instead download an eSIM profile, either via an app or by scanning a QR code.

Then you simply choose your prepaid eSIM plan, and off you go – you’ve now got a pay-as-you-go eSIM to avoid those big roaming data charges when you are off on your hols or traveling internationally for business.

Because there’s no need to go to a shop to get a new SIM card or wait for one to be sent through the post, you can join a new network in a matter of minutes, wherever you are.

How does eSIM work – for traveling in Vietnam

Being able to change to a different network instantly can be incredibly useful when traveling. You might find that your home country’s network charges exorbitant data roaming fees if you use your phone abroad – but you can avoid those fees by switching to an eSIM profile with a prepaid eSIM plan. Then when you get home, you can simply switch back to your regular SIM.

And there are other cases in which having a connection to a different network via an eSIM can be useful, like when your phone is in an area where your main network doesn’t have coverage. In that case, you could swap to your eSIM profile to see whether that network has a signal. Another advantage of having both a SIM and eSIM is that you could use one for business and the other for personal calls, without having to swap phones – instead of just swapping profiles. Sounds easy, right? Well, it is!

eSIM setup – how it’s so easy

You can easily swap between the network on your eSIM and the one on your physical SIM at any time by going into ‘Mobile Data > Data Plans (Apple devices) or Connections > SIM Card Manager (Samsung devices)’ in your phone’s settings and switching between the two. You can also store more than one eSIM profile, although you can only use one profile at a time.

As the Internet of Things evolves, eSIMs and eSIM providers in the UK are cropping up more and more because more objects, like cars and traffic lights, or anything that might need to connect to a mobile network, are being manufactured with an eSIM built in.

Because eSIMs can be updated electronically, it means new profiles can be added without, for example, physically swapping thousands of SIM cards in traffic lights up and down the country. eSIMs are the future!
