Switching from a traditional SIM card to an eSIM is becoming increasingly popular with UK businesses — and for good reason. eSIM technology offers unmatched flexibility, convenience, and scalability, making it a smart choice for companies who want to streamline the ways they stay connected.
If you’re considering making the switch from physical SIM to eSIM, we’ll walk you through everything you need to know, from understanding exactly what eSIMs are, to how to complete the conversion seamlessly.
What is eSIM technology?
An eSIM, or embedded SIM, is a small chip that is built directly into your device. eSIMs work just like traditional SIM cards, but without the need for any physical hardware. Unlike standard SIM cards, eSIMs are activated remotely and can store multiple profiles, letting you switch networks or numbers effortlessly.
Key advantages of eSIMs for small businesses
Businesses love using eSIMs for many different reasons:
- Remote activation: There’s no waiting for SIM cards to arrive. Instead, you can activate your plan and use your new number instantly.
- Multiple profiles: You can use one device for both personal and business lines.
- Eliminates physical cards: With an eSIM, you don’t have to worry about misplacing or damaging SIM cards, as all the data is stored directly within the device.
For small businesses, eSIMs are a game-changer. They simplify communication, reduce costs, and make it easy to scale up as your team grows.
Your step-by-step guide to converting to eSIM
Ready to make the switch? While the exact process will vary depending on your particular eSIM provider, the main steps will be the same for most devices. Here’s how to convert your physical SIM to an eSIM:
1. Check your device’s compatibility
Make sure your device supports eSIM technology. Some of the most popular eSIM-compatible models in the UK include:
- iPhone models from the XS onwards
- Samsung Galaxy S21 and newer
- Google Pixel 3 and newer
Unsure? You can usually find this information in your device settings under “About” or “SIM & Network.”
2. Contact your mobile network provider
Get in touch with your provider to request an eSIM, and let them know whether you want to convert from physical SIM to eSIM, or keep both SIMs active on your phone. They’ll provide you with an activation method for the eSIM, typically a QR code or an activation link.
3. Back up your data
Before you start the process, back up your contacts and important files to avoid any data loss during the transition. It’s better to be safe than sorry, particularly with your valuable business data.
4. Activate your eSIM
All manufacturers and devices are different, so the wording in the steps below may vary slightly, but the process should essentially remain the same.
For iOS devices, follow the steps below to activate your eSIM:
- Open Settings, then Mobile Service, then Add eSIM.
- Scan the QR code provided by your network.
- Follow the on-screen instructions to complete the setup.
For Android devices, follow the steps below to activate your eSIM:
- Go to Settings, then Connections, then SIM Card Manager, then Add Mobile Plan.
- Select Scan Carrier QR Code or follow the instructions for manual input.
Confirm the setup and enable the eSIM profile.
5. Test it out and troubleshoot if needed
Once activated, your eSIM profile should be visible in your device’s SIM settings. Test by making a call or sending a message to ensure everything is working.
Troubleshooting during the conversion from SIM to eSIM
Encounter a hiccup? Most problems can be easily sorted. Here are a few common issues and how to fix them:
Problem 1: My device doesn’t support eSIMs
Double-check your device compatibility before you make the switch. If your current phone doesn’t support eSIMs, consider upgrading to an eSIM-capable model.
Problem 2: The QR code isn’t working
Try scanning the code again in good lighting, and make sure that your phone is connected to the internet. If it doesn’t work, contact your provider for a new code or further instructions.
Problem 3: I’m experiencing network connection problems
If you’re experiencing network connection issues after switching to an eSIM, try restarting your phone, and make sure you’re in an area with good cellular coverage. If you’re still experiencing difficulties, reach out to your provider for additional support.
For persistent issues, reaching out to your network provider’s support team is the quickest way to resolve them.
The benefits of converting to eSIM from physical SIMs
Switching to eSIMs offers plenty of perks that can transform the way your business operates:
- Flexibility: With eSIMs, you can manage personal and business numbers on one device or switch networks effortlessly.
- Scalability: eSIMs allow you to easily add or manage lines for new employees without the need to wait for physical SIM cards.
- Cost efficiency: Once you’ve converted to an eSIM, there’s no need for replacement SIM cards, reducing hardware costs.
- Streamlined operations: eSIMs are ideal for remote teams or employees who travel frequently.
