Why business owners are making the switch to eSIM
eSIM is a digital alternative to a physical SIM card that's built into many modern devices.
For small and medium-sized businesses, eSIM makes it easier to manage mobile services, separate work and personal numbers, and connect employees without handling physical SIM cards.
This article explains how eSIM works, how it benefits your business and how to get started.
What is an eSIM?
An eSIM, or embedded SIM, is a digital SIM built into your device. Unlike a traditional SIM card, you don’t need to insert or swap it physically.
You can activate an eSIM remotely when your device supports it, so you don’t need to visit a store or wait for a physical SIM card. This makes it easier to deploy and manage mobile services across your business.
Many compatible devices also support multiple mobile services, so you can keep your work and personal numbers separate on one phone.
Why eSIM is worth considering for your business
Small and medium-sized businesses often need practical solutions that are easy to manage. eSIM simplifies how you activate, manage and use mobile services across your business.
Easy setup
Activate eSIM services digitally to connect employees without managing physical SIM cards. It’s as simple as scanning a QR code and following the prompts on your device.
This simplifies staff onboarding, device replacements and mobile service rollouts across multiple locations.
Improved security
Because an eSIM is built into a device, it can't be removed like a traditional SIM card. This can provide an additional layer of protection when businesses use mobile devices to communicate with customers, access systems or manage day-to-day operations.
Work and personal numbers on one device
Many eSIM-compatible devices support multiple mobile services, so you can keep your work and personal numbers separate on one phone.

Supporting business flexibility
Whether you're hiring new employees, replacing devices or supporting hybrid work, eSIM makes it easier to manage mobile services as your business changes and grows.
As your needs evolve, review your mobile phone plan to make sure it continues to support your business.
Reducing waste and emissions
eSIM reduces the need for physical SIM cards, packaging and shipping, so fewer materials are required to connect employees and manage mobile services.
Telstra's eSIM QR card packaging uses recyclable materials as part of our efforts to reduce waste. Using fewer physical SIM deliveries may also reduce transport and delivery-related emissions.
Getting started with eSIM for your business
Follow these steps to switch your business to eSIM.
Check device compatibility
Before you switch, confirm that your smartphone, tablet or laptop supports eSIM.
A device will only have an EID, or Embedded Identity Document, if it supports eSIM. The EID serial number is usually printed on the box of your device.
You can also find your EID:
- On a smartphone, by dialling *#06#
- On a Tablet, in Settings > About
Most devices released after 2020 are eSIM compatible, but some overseas variants may not be. If you’re unsure, check your device manufacturer’s website.
Choose a business mobile plan
Review your business requirements and select a plan that suits the way your team works.
Consider how many employees need a mobile service, how much data your team uses, how often employees travel and how easily you need to add or change services as your business grows.
