5 Business Benefits of eSIMs

Discover the business benefits of eSIMs, the embedded SIM technology that enhances flexibility, security, and cost-efficiency. Learn how eSIMs work, their setup process, and why they are advantageous for enterprise organisations.

What is an eSIM?

An eSIM, or embedded SIM, is a small, programmable SIM card embedded directly into a device. Unlike traditional SIM cards, which are removable, eSIMs are built into the device’s hardware. They store multiple profiles and allow users to switch between networks without physically changing the SIM card.

How to Set Up an eSIM

Setting up an eSIM is straightforward but may vary slightly depending on the device and network. Here’s a general step-by-step guide:

  1. Check Device Compatibility: Ensure your device and network supports eSIM technology.
  2. Obtain an eSIM Profile: Contact your network to get an eSIM profile. They will provide a QR code or an activation code.
  3. To activate the eSIM, go to your device’s settings.
  4. Navigate to the data network section.
  5. Select “Add Data Plan” or a similar option.
  6. Scan the QR code or enter the activation code provided by your network.
  7. Once the eSIM profile is added, configure your settings such as primary and secondary data plans if you have multiple profiles.
  8. Ensure that the eSIM is active by testing the connection with calls, messages, or data usage.

Benefits of eSIMs for Businesses

1. Flexibility and Convenience
eSIMs allow businesses to manage multiple mobile plans without the need for physical SIM cards. This is particularly beneficial for companies with employees who travel frequently or use multiple devices. The ability to switch between different networks seamlessly ensures that employees remain connected wherever they are, enhancing productivity and operational efficiency.

2. Cost Savings
Businesses can save on roaming charges by switching to local networks when travelling. Additionally, managing mobile plans remotely reduces the need for physical logistics and reduces administrative costs. eSIMs eliminate the need to purchase and ship physical SIM cards, which can lead to significant savings, especially for large organisations.

3. Enhanced Security
eSIMs provide enhanced security features, including remote management and encryption. For businesses that handle sensitive data, the ability to remotely activate or deactivate eSIM profiles ensures that lost or stolen devices can be quickly secured, reducing the risk of data breaches.

4. Simplified Device Management
IT departments can easily manage mobile plans across the company. This includes activating, deactivating, or switching plans without handling physical SIM cards, streamlining operations. Centralised management of eSIMs allows IT teams to quickly respond to changes in network needs, deploy updates, and troubleshoot connectivity issues more efficiently.

5. Sustainability Benefits
eSIMs reduce the need for plastic SIM cards and their packaging, cutting down on plastic waste and carbon emissions associated with manufacturing and shipping physical SIMs. Adopting eSIM technology helps businesses reach their sustainability goals sooner by reducing their environmental footprint.
