@Terry468 You call customer support as they can see all numbers on your account, If this is a contract you’ll be required to pay off any remaining term of that contract, in full in one payment. You just give 30 days notice to terminate.
You should have requested a replacement sim to continue using that number.
To contact EE Customer Services dial 150 From your EE mobile or 0800 956 6000 from any other phone.
