leaving ID Mobile without phone number

Your eSIM does have a number, they all do. You just don’t know it! Also, cancelling the direct debit doesn’t cancel your plan, but it will ruin your credit file if your account goes overdue, making it difficult to obtain credit in the future.

The terms and conditions of service tell you what you must do in order to cancel your plan:

17.1 If you want to end your agreement, you must contact us through the 'Contact Us' section in our website at www.idmobile.co.uk/contactus and give us at least 30 days notice or alternatively you may log in to your account using the iD app and set a future disconnection request by selecting a date which is at least 30 days in to the future. If you prefer to contact iD Mobile via letter, please send this to iD Mobile, PO Box 686, Salford M5 0PA. You must include your full name, your billing address with post code, your iD mobile telephone number and the name of the bank your direct debit is with to help us locate your account. If you would like to give us notice beyond 30 days in to the future, you can contact us at www.idmobile.co.uk/contactus for more details. Whenever you have a No Fee Right to Exit you must exercise it within 30 days of it arising; if you do not notify us within this period, you will lose the right to terminate.

So, get on to live chat and give them at least 30 days notice as stated above.

Hi ​@Sam Barrett  Would you like for us to check the number for you?

If you still wish to cancel, as ​@WelshPaul  has advised, cancelling the Direct Debit won’t cancel the plan, but we can assist you with this if this is what you are wanting to do?
