An eSIM is a digital SIM that lets you activate your mobile plan without needing a plastic SIM card. It’s perfect for newer smartphones, easy to set up, and ideal if you want to switch networks quickly or travel frequently.

Many UK networks now support eSIM on SIM Only deals — just look for in our listings.

At Olimit, we make it easy to compare eSIM-compatible deals, so you can go digital and get connected instantly.

Olimit Tips & Tricks

Is eSIM better than a physical SIM?

It depends on your needs. An eSIM offers more convenience — there’s no need to wait for delivery or insert a physical card – perfect for travel. You can switch networks instantly, store multiple profiles, and manage everything digitally. It’s especially useful for frequent travellers or those who change providers often.

However, if your phone doesn’t support eSIM or you prefer a traditional setup, a physical SIM still works just as well. At Olimit, we list whether a deal supports eSIM, so you can choose the option that works best for you.

Can I use an eSIM while travelling abroad?

Yes, and it’s one of the best reasons to get one. An eSIM makes travel easier by letting you download a local or travel SIM plan before you even land — no need to hunt for a shop or swap physical cards. Many global and UK providers offer international eSIM plans, ideal for tourists, remote workers, or frequent flyers.

At Olimit, you can compare eSIM-ready SIM Only deals that support international roaming, so you stay connected wherever you go.

Everything You Need to Know About eSIM Plans

Including how to activate, compare plans, and switch with ease.

What Is an eSIM? Explained

An eSIM is a digital SIM that’s already built into your device. Instead of inserting a physical card, you simply activate your mobile plan by scanning a QR code or using an app. It’s perfect for people who:

Want to go 100% digital and ditch the plastic SIM card.
Travel frequently and need to switch between networks without swapping SIMs.
Use dual SIM devices and want two plans on one phone.

With eSIM, there’s no delivery, no waiting — you can connect to a network within minutes.

Why Are eSIM Plans Growing in Popularity?

eSIMs are becoming the new standard for a good reason:

Instant activation. No need to wait for a SIM card in the post — get connected immediately.
Travel-friendly. Add a local eSIM when abroad without removing your main UK number.
Better for the planet. No plastic, no waste — just clean, digital convenience.
Multi-SIM power. Run both work and personal numbers on one device.

Why Choose Olimit for eSIM Plans?
