@Peteshaw94 If this is a pay as you go sim just stop using it and don’t top it up. If it’s a contract sim you’ll need to call customer services to give 30 days notice to terminate that contract but if your still within your contract term you’ll have to pay off the remainder term of that contract.
To contact EE Customer Services dial 150 From your EE mobile or 0800 956 6000 from any other phone.
