Fuse
For families

One provider for the whole household

Kids' first phones. Teens at school. Parents working. Grandparents who just need to call. Fuse covers all of them — separate plans, separate numbers, one provider to deal with.

Recommended for families

Spark — £5.99/month

Light users on Wi-Fi most of the time

See all plans

Mix and match by user: Spark at £5.99 for kids who mostly use Wi-Fi, Pulse at £9.99 for teenagers and working parents, Surge at £14.99 for heavy users or grandparents who travel. All on one account, one bill if you want it.

Why Fuse works for families

  • Each line on its own plan

    No 'shared family pot' that one heavy user drains. Each phone gets its own allowance, on its own plan, separately upgradeable. Switch a teenager from Spark to Pulse for £4 more if they're going over.

  • First phone in five minutes

    Kid's first phone? Activate the eSIM by scanning a QR code — no shop visit, no second SIM in the post that gets lost. Works on hand-me-down phones too, as long as they're 2020 onwards.

  • Coverage that works at home AND school

    School in a different network's weak zone from home? Fuse uses all four UK networks. Your kid's phone stays connected at home, at school, and on the school run between.

  • No two-year contracts to inherit

    Big networks lock families into 24-month contracts per phone. When a kid loses their phone or grows out of their plan, you're stuck. Fuse is rolling monthly — leave or change any line, any month.

Modern family mobile is messy. One provider for the parents on contract, a giffgaff SIM for the eldest, pay-as-you-go for the youngest, a SIM the grandparents barely use sitting in a drawer. Different bills, different end dates, different problems when something goes wrong.

Fuse consolidates that. One provider, one account, separate plans per family member. Each phone gets the right level of data for that user — Spark for kids, Pulse for teens, Surge if someone travels — and you can scale any individual line up or down without disturbing the rest. No 24-month contracts to inherit, no shop visits to swap SIMs.

Yes. One account holds multiple lines — each with its own plan, number and data allowance. Manageable from the Fuse app or web dashboard. Switch a line up or down, pause, or cancel individually.
Spark at £5.99/month is the obvious starting point — 5GB is more than enough for the level of use a younger child typically has (they're on home/school Wi-Fi most of the time). Upgrade as they grow.
If the phone supports eSIM, yes. Most phones from 2020 onwards do — iPhone XS+, Galaxy S20+, Pixel 4+. Check the device list before you commit. If the hand-me-down doesn't support eSIM, it's a sign it's time for an upgrade anyway.
Setup needs someone to scan a QR code once. After that, the phone just works — no SIM tray to fiddle with, no settings to learn. A more tech-confident family member can help do the initial setup, and Fuse customer service can guide over the phone.
Big-network family plans often look cheap headline (multi-line discounts) but lock you into long contracts and hidden price rises. Fuse stays at the published price, no contracts, no annual hikes — usually cheaper over a 2-year horizon for 4-5 lines.
