Issues buying a plan

If you don’t already have a plan

It could be a number of things:

  • Your credit/debit card may have expired

  • There could be a typo in your payment details, make sure they're entered correctly

  • The transaction could have been declined by your bank. In some of these cases you may just need to wait a few hours, clear your browser's cookies, and try again

If you already have a plan and can't buy another.

This could be caused by a number of things, such as:

  • You still have data left in your current plan. If you try to buy a new plan while you still have more than 500MB, your plan will be queued but won't activate before the previous one expires

  • If it's after 9pm and your plan is expiring tonight or has already expired then the system 'locks out' all plan purchases until after midnight

  • You’ve set your plan to recur. If you want to manually buy your next plan then switch off your recurring plan first here

  • You already have a queued plan. If you want to change the plan you have queued then you need to cancel your existing queued plan

Issues adding credit

This could be happening for a few different reasons:

  • If you’re using a voucher, you may have entered an invalid voucher code

  • Your credit/debit card may have expired

  • There could be a typo in your payment details

  • The transaction could have been declined by your bank. In some of these cases you may just need to wait a few hours, clear your browser's cookies, and try again

  • If you’re using a UK card from abroad, payments may be rejected by your bank for security reasons
