Question 1

What is Fuse Mobile?

Accepted Answer

Fuse Mobile is a multi-network eSIM provider that gives you access to all four major UK networks (EE, Three, Vodafone, and O2) through a single eSIM. Your phone automatically connects to the strongest signal available, so you always get the best coverage.

Question 2

How is Fuse different from other mobile providers?

Accepted Answer

Unlike traditional providers that lock you to one network, Fuse uses all four UK networks. This means better coverage, fewer dead spots, and a more reliable connection wherever you are. It's like having four networks for the price of one.

Question 3

Do I need a new phone number?

Accepted Answer

No, you can keep your existing phone number. When you sign up, we'll help you transfer your number over to Fuse. The process usually takes just a few hours.

Question 4

What is an eSIM?

Accepted Answer

An eSIM (embedded SIM) is a digital SIM built into your phone. Instead of a physical SIM card, your phone's connectivity is activated digitally. This means no waiting for a SIM card in the post — you can be connected in minutes.

Question 5

Is my phone eSIM compatible?

Accepted Answer

Most modern smartphones support eSIM, including iPhone XS and later, Samsung Galaxy S20 and later, Google Pixel 3 and later, and many more. Check our device compatibility tool on the How It Works page to confirm your device.

Question 6

Can I use an eSIM and a physical SIM at the same time?

Accepted Answer

Yes! Most eSIM-compatible phones support dual SIM — one physical and one eSIM. You can use your Fuse eSIM for data alongside your existing physical SIM for calls, or use Fuse for everything.

Question 7

How do I install the eSIM?

Accepted Answer

After signing up, we'll send you a QR code. Simply scan it with your phone's camera, follow the on-screen instructions, and you'll be connected in under 5 minutes. No technical knowledge required.

Question 13

What happens when I run out of data?

Accepted Answer

When you use all your data allowance, your data connection will be paused until your next billing cycle. You can upgrade your plan at any time to get more data immediately.

Question 14

Can I top up my data mid-cycle?

Accepted Answer

You can upgrade to a higher plan at any time, which takes effect immediately. We'll prorate the difference so you only pay for the remaining days in your billing cycle.
