UK plan questions

Which UK plan is right for me?
Think about how much data you use in a month. Light users do well with a few GB, regular users with 20 to 50 GB, and heavy streamers or hotspot users with 100 GB or unlimited. Open View details on a card to check the small print.
What is the difference between contract, rolling and pay as you go?
An 18-month contract keeps the same price for the contract period and suits long-term use. A monthly rolling plan renews each month and lets you switch plan monthly. A pay as you go plan is a simple one-month plan with total flexibility.
Is the price locked on an 18-month contract?
There are no mid-contract price rises on 18-month contracts bought before the end of 2026. Fair usage policy, terms and exclusions apply.
Are there credit checks?
The 18-month contract plans shown here are offered without credit checks.
Can I change my plan later?
Yes. Contract plans can be changed anytime, and monthly rolling plans can be switched each month.
Are calls and texts included?
Every plan on this page includes unlimited UK calls and texts.
Do the plans include 5G?
Rolling and pay as you go plans include 5G speeds at no extra cost, and the network offers 4G and 5G coverage. Actual speeds depend on your device and location.
Can I use my plan in the EU?
You can use up to 5 GB of your allowance in the EU at no extra cost. Please check your destination before you travel.
Can I keep my old phone number?
In most cases you can move your number to a new SIM using a transfer code from your old provider. Ask your current provider how to get it.
Can I add a plan when I buy a SIM?
Yes. Choose a plan with a new SIM or add it to a SIM you already own. Plans are added to your cart and you save 10% at checkout.
How do I activate and recharge my SIM?
Find the 6-digit code on the back of your SIM and use the activation section on the Mobile Plans page. To recharge, enter your number and amount there and pay with the methods available at checkout. Activation is generally completed within 24 hours.
Where can UK SIM cards be delivered?
UK SIM cards are intended for UK addresses. Delivery options are shown at checkout.
What happens when my plan ends?
Its data benefits stop until you add or renew a plan. Please renew before your plan period ends to stay connected.
