Add-ons: pay for what you actually use.
Most networks bake roaming, international calling and "just in case" data into every month's bill — whether you use them or not. We don't. Your monthly plan covers your everyday life at home, and everything else is an add-on you buy only when you actually need it:
- Never travel? Then you never pay a penny towards roaming.
- Not sure how much data you need? Start on a smaller plan and top up when a month runs heavy. If you find yourself topping up regularly, that's your sign to move up a plan size — and we'll tell you so, not quietly pocket the difference.
One-off purchases. Nothing auto-renews. Nothing hides in your monthly bill.
Need more data? Top up in minutes.
One-off data top-ups for the line you already have. No minimum term, no auto-renewal, no surprises — buy it once, use it when you need it.

How it works
- Sign in and pick which of your lines to top up.
- Pay once — your top-up is usually applied within minutes.
- It waits in reserve. Your plan data is always used first; your top-up only starts when you actually need it — and its 30 days only begin then.
Your top-up never goes to waste. Buy it today, and it sits ready on your line until your plan data runs out. 30 days of validity, counted from first use — not from purchase.
Top-ups are one-off purchases and never auto-renew. Data top-ups are valid for 30 days from first use; the 1-Day Unlimited runs for 24 hours from first use. One top-up can be queued on a line at a time. Changed your mind? Contact us within 14 days for a full refund, as long as the top-up hasn't been used. Once you start using it, it can't be refunded. None of this affects your statutory rights.
Travelling in Europe? Take your data with you.
Travel packs for 29 destinations — the 27 EU countries, Switzerland and Turkey. Each pack adds a one-off boost of data to the line you already have, and starts by itself when you arrive.
- 2GB EU Travel Pack £2.99 A long weekend away, sorted. Sign in to add
- 5GB EU Travel Pack £5.99 A week or two without watching the meter. Sign in to add
- 10GB EU Travel Pack £10.99 A month abroad, video calls home included. Sign in to add
- 20GB EU Travel Pack £14.99 The big one — for when your phone is your office. Sign in to add
How it works
- Sign in, pick your line, and add the pack whenever suits you — before you fly, or once you are there.
- Nothing to switch on. When your phone connects to a network in one of the 29 destinations, the pack starts by itself.
- Your validity — 7, 15 or 30 days depending on the pack — runs from that first use abroad, not from the day you bought it.
Buy it whenever suits you. Your travel pack works alongside your UK plan, so buying early takes nothing away and holds nothing up. The clock only starts when you first use it abroad.
And when you come home? Your UK plan takes over again automatically. Nothing to cancel, nothing to switch off.
Travel packs work in the 29 covered destinations (the 27 EU countries, Switzerland and Turkey) and can't be used inside the UK — not before you leave, not after you're back. The pack starts automatically once your phone connects to a network in a covered destination, and its validity (7, 15 or 30 days) runs from first use. One-off purchase, no auto-renewal. Travel packs work alongside your UK plan. Changed your mind? Contact us within 14 days for a full refund, as long as the pack hasn't been used. Once you start using it, it can't be refunded. None of this affects your statutory rights.
