What is an eSIM and what can it do for your business?

Everything you wanted to know about an eSIM and how it can help small business owners improve their efficiency
What is an eSIM for business?

Most people’s idea of a Subscriber Identity Module (SIM) is a piece of hardware that they put into their phones to activate a phone number. But the physical version is being replaced by the digital version or an Embedded Subscriber Identity Module (eSIM).

While you may have never thought about getting an eSIM, it pays to know about this disruptive piece of technology. If you’re a local business owner or freelancer, there are tremendous advantages that it can unlock for both your business and personal lives.

What is an eSIM?

An eSIM is a SIM card that’s embedded into your phone. When you buy a smartphone with an eSIM facility, you don’t have to put another physical card into it to get a number.

The smartphones that support eSIM as of now also support physical SIM cards. This means that you’ll be able to use your existing number through the physical SIM and get a second phone number for work through the eSIM.

For your eSIM to be functional, your network needs to support it. At the time of writing, not all networks support eSIM but with increasing adoption and competition, major networks and carriers will support it in the near future.

What’s important to know is that the traditional SIM card can be removed from your phone. If you sell your device or give it to someone else in your family to use it, you’ll be able to take out your SIM and put it in another device. But you can’t remove the embedded eSIM from a phone.

What are the advantages of an eSIM?

  • You get two numbers: Since all the current eSIM-enabled phones also support the traditional physical SIM, you get to have two phone numbers with a single device. You can use that second phone line for work to separate your business and personal communication.

  • Easy to change networks: Changing networks or carriers is easy with eSIM as they are rewritable. With the conventional SIM cards, you’ll have to buy a new SIM then put it into your device. If you have an eSIM phone, you’ll be able to change networks online or with just a call. Your carrier will reprogram your eSIM quickly.

  • You can have several SIMs: With a single eSIM, you’ll be able to store up to five virtual SIM cards or temporary mobile numbers provided by your operator. This makes eSIMs the perfect option when you travel. You don’t have to worry about getting a new physical SIM card from a foreign country, not to mention the annoyance of taking out your SIM.

What are the disadvantages of an eSIM?

  • You’re tied to your device: If you use a traditional SIM card, you can easily change your devices. If you decide to upgrade your smartphone, all you have to do is take out your SIM and insert it into the new phone. With an eSIM, you can’t do that.

  • Easier to track: If you have concerns about being tracked, it’s a problem. Although it is a major advantage if your phone gets stolen as eSIMs cannot be removed.

Is an eSIM the right option for my business?

If you’re a small business owner, you should consider getting a phone that’s eSIM-enabled. Without buying a new phone, you’ll have a second phone number that you’ll be able to share with customers and clients.

Second-line apps are also an effective option to separate your professional and personal communication. You can easily download a second phone line app and activate a number in a few minutes. With a second number app for work, you’ll also get access to add-on features such as auto-response texts.

A second phone line app will also ensure privacy and importantly, make it easier for you to achieve a better work-life balance without compromising on efficiency.

A viable option

eSIM-enabled phones may remove the need for physical SIM cards once there’s more widespread adoption. For all those looking for a second phone number for work, they are a viable and functional option.
