    Frequently asked questions.

    • Switching to a new SIM plan.

      Already on a 12 month SIM plan? You can switch to one of our new plans any time you like. It's really easy – we just move your new plan details on to your existing SIM.

      You don't have to pay a fee or sign a new contract – your original contract-end date stays the same (though the amount you pay may change to reflect your new allowance).

      On a 1 month SIM plan? Just give us 30 days' notice and you can switch to one of our new plans.

    • Upgrading your SIM plan.

      Need more minutes or data? No problem.

      If you're on a 1 Month SIM plan, just give us 30 days' notice and you can switch to any of our new plans.

      If you're on a 12-month SIM plan, you can upgrade to a plan with more minutes or data whenever you like (if you want a plan with fewer minutes or data, you'll need to wait until your contract ends).

    • Getting a new SIM card.

      Sign up to one of our new SIM plans today and you'll have your new SIM in 1 - 3 days.

    • How long does the £2 off introductory offer last?

      If the plan you have selected is marked “With £2 off: introductory offer” you just need to sign up by 30 September to get the advertised monthly price which takes this offer into account. This is the price you will pay for your plan throughout your contract with us.
