eSIMs are fast becoming the standard for businesses looking to improve the way they connect and communicate.

These digital alternatives to traditional SIMs are embedded into the device itself (your smartphone, tablet or smartwatch, for example). But why are they so popular, exactly?

Here, we explore eSIMs in more detail, examine how they work and compare their benefits to traditional SIM cards.

What is business eSIM?

A business eSIM is an electronic version of a physical SIM, or “Embedded Subscriber Identity Module.”

Unlike traditional plastic SIM cards, an eSIM is a piece of code embedded in your device that can't be removed and installed on another phone or tablet.

With a business eSIM, you can activate a mobile plan from your service provider without ordering or inserting a physical SIM card into your devices.

The eSIM profile is loaded onto your device through an internet connection, and contains the same information previously stored on a physical SIM.

How does a business eSIM work?

The eSIM is embedded in your phone. You can’t remove a business eSIM the way you would remove a physical SIM card or IOT SIM.

But you can program your eSIM to adapt to different providers' services. So, for example, to make calls, send texts and connect to the network, you have to activate the eSIM.

It’s simple to set up an eSIM for most devices. You just scan the QR code that registers your eSIM profile with your mobile network.

Some networks may require you to enter a code. Either way, it only takes a few minutes, and you’re all set up.

If you have an iPhone, things are a tiny bit different. You need to go to:

Settings > Mobile Data > Add Data Plan on your device. From there, you can scan your QR code.

eSIMs can also work with many tablets and smartwatches. So, if you’re looking to add eSIMs to your business’s connectivity ecosystem, we can help you choose the best provider for your phone. Or the best handsets with eSIM for business.

The benefits of business eSIM

Many businesses are making the switch to eSIMs as they’re easier to set up at scale and typically provide a smoother user experience.

On a business level, eSIMs offer a mix of operational benefits, including:

• Quick remote activation for new employees
• Less packaging and plastic waste
• Typically lower roaming costs as you can switch easily between local carriers

If you’re a scaling business with ambitious growth plans, choosing business eSIMs over physical SIMs can help to improve your operations. Here’s how:

• You can have multiple phone numbers on a single SIM phone with a business eSIM: For example, you can have your personal number on your SIM-only card and your business number on your eSIM. You can even choose which plan you use for data, calls and messages for added flexibility.
• It’s easy to reprogram an eSIM: If you’re looking to change providers, all you need is a QR code or the provider’s mobile app that automatically reprograms the eSIM.
• It’s an ideal choice for employees who travel a lot: a business eSIM is the easiest way for them to communicate and stay in touch from anywhere in the world.
• eSIMs are more secure: As eSIMs are embedded into the device, no one can remove it if a phone is lost or stolen. This makes your device and business information more protected against unauthorised SIM swapping.
• eSIMs are environmentally friendly: SIM cards generate a lot of plastic waste and carbon dioxide. Since eSIMs are embedded into your phone’s motherboard, you’ll help to eliminate waste.

You also might be wondering, “how many eSims can I have?” Usually, you can install eight or more eSIMs on compatible devices with two phone numbers active at the same time.

The potential setbacks of eSIMs

While there are multiple benefits to business eSIMs, there are also some potential drawbacks you should know about:

• You need an unlocked phone to switch between carriers and get more flexibility.
• If your phone is damaged or broken beyond repair, the eSIM can’t simply be removed and put into another device. You’ll have to reinstall the eSIM as you did the first time.

While these are minor cons, the benefits of using business eSIMs typically outweigh the drawbacks.
