eSIM technology is changing the way we connect, and for UK small businesses, it’s quickly becoming an essential. Unlike traditional SIM cards, eSIMs are built right into your device, offering simple, convenient and flexible plan management.
Whether you’re managing a growing team, juggling personal and business numbers (or just fed up with swapping SIM cards), an eSIM could be exactly what you need. In this guide, we’ll go through the need-to-know info when it comes to eSIM technology, including what eSIMs for business are, how to get one, and why they’re perfect for small to medium businesses.
What is eSIM technology?
Let’s start with the basics: an eSIM, or embedded SIM, is a digital version of the standard SIM card. It’s built directly into your device, meaning there’s no need for the little plastic card you’re used to. With an eSIM, everything is done digitally: your mobile plan is activated remotely, and you can even store multiple profiles on a single device.
What makes eSIMs a game-changer for small businesses?
- Instant activation: No waiting around for a SIM card to arrive in the post.
- Multiple profiles: Use one device for both work and personal numbers.
- No physical cards: You’ll never misplace or damage a traditional SIM card again.
- Easy to port: Change your plan provider quickly and simply, so you can make the most of special offers and local tariffs by converting to eSIM.
For small businesses, eSIMs simplify communication, save you money, and can be scaled up easily as your team grows. You can even use an eSIM and regular physical SIM at the same time if you want to.
Step-by-step guide: How to get an eSIM
Getting an eSIM in the UK is simpler than you might think. Here’s how it works:
Check your device compatibility
First, make sure your device supports eSIMs. Most modern smartphones do, including iPhones from the XS onwards or newer Android models like the Samsung Galaxy S21. To confirm, check your phone’s settings under “About” or “SIM & Network.” If your current device doesn’t support eSIM, consider upgrading so you can harness the benefits of eSIM tech.
Contact your mobile network provider
Reach out to your provider (such as EE, Vodafone, or O2) and request an eSIM. Let them know if you want to replace your current SIM or use both SIMs at the same time. They’ll typically send you a QR code to activate your eSIM.
Activate your eSIM
Once you have the QR code, follow the setup instructions on your device. Each device will have a slightly different process, but if you follow the on-screen instructions, it’s normally very easy to do. Here’s a rough guide to get started on iPhones and Androids:
- For iPhones: Go to Settings, then Mobile Service, then Add eSIM and scan the code. Follow the on-screen instructions to complete the process.
- For Android phones: Go to Settings, then Connections, then SIM Card Manager, then Add Mobile Plan. Follow the on-screen instructions to complete the process.
Test it out
After activation, make a call or send a message to ensure everything’s working. If not, contact your provider and request some help with your issue.
Pro tip: When YourBusinessNumber’s eSIM solution launches, the process will be even faster. Simply order online, get your eSIM in under 10 minutes, scan the code, install WhatsApp Business, and you’re all set!
What to expect during the eSIM setup process
Here’s what to keep in mind when switching to an eSIM:
- Timelines: Activation is usually extremely quick, but it may vary depending on your provider. If you need to work within a particular time frame, let your provider know before you start the setup process to make sure you’ll be up and running by your deadline.
- Costs: Some providers charge a small fee for eSIMs, but many include it as part of their plan. Again, it’s a good idea to confirm the details in your initial call to your provider, so you don’t get caught out with any hidden bills.
- Deactivating a physical SIM: If you’re switching entirely to an eSIM, your physical SIM will need to be deactivated. Your provider will be able to explain the process for this, but you normally won’t need to do anything other than dispose of the old SIM card.
Why eSIMs work for UK small businesses
eSIMs come with several perks that make them perfect for small businesses:
- Flexibility: Switch between personal and business numbers on the same device, or swap providers effortlessly.
- Scalability: Adding new team members is a breeze with eSIM technology. There’s no waiting for physical SIMs to arrive, and no need to deliver them to your new team members.
- Efficiency: Faster activation times mean you’re up and running in no time, especially when compared to traditional SIM cards. You can also wave goodbye to fumbling with tiny SIM cards, as eSIMs take all the hassle out of the setup process.
- Global connectivity: eSIMs make it easier to access international plans and benefit from local tariffs, making them ideal for businesses with overseas clients.
- Better security: eSIMs are embedded directly into your phone, so there’s less chance of losing or damaging them when compared to physical SIM cards. For businesses, that means safer and more secure communications.
- More environmentally friendly: Switching to eSIMs isn’t just good for your business, it’s good for the planet too. By cutting out the need for plastic SIM cards and their packaging, eSIM tech helps to reduce waste.
- Quick replacements: If your device is ever lost or damaged, eSIMs can be reprogrammed remotely, saving you the hassle and disruption of waiting for a new SIM to be delivered.
- Dual SIM solutions: Many eSIM-enabled devices allow for dual SIM functionality, meaning you can keep your work and personal numbers on the same phone without needing two physical SIM cards. It’s a simple, practical solution for staying organised. And yes, you can also use an eSIM for WhatsApp Business, too!
UK eSIM business considerations
When choosing an eSIM for your business, here’s what to look out for:
- Network support: Most large UK network providers, including EE, Vodafone, Three, and O2, offer comprehensive eSIM support. If you’re going with a smaller provider, check reviews to make sure that their customer service is robust.
- Device compatibility: Ensure your devices are eSIM-enabled before you begin the activation process. Otherwise, you may need to upgrade to a newer model so you can benefit from an eSIM setup.
- Roaming options: If you travel internationally, check your provider’s roaming plans to see if they meet your needs. Not happy with their offering? With eSIM it’s easier than ever to port across to a new provider, so you can find a plan that suits you.
Top tips for a smooth eSIM setup
To make your transition to eSIM as seamless as possible:
- Check your contract: Speak with your provider to ensure you’re eligible for an eSIM.
- Back up your data: Save your contacts and files before switching, just to be safe.
- Experiment with profiles: If you’re using multiple numbers, take the time to organise them for easy management.
