Hi, I am wondering if anyone could help me with the problem I am having with my Vodafone online account.

I am wanting to offer my Vodafone mobile broadband dongle possibly with a sim on Freecycle as I no longer need it. However, the sim is linked to my online account that I set up to top up credits using a registered card. I just do not feel very safe to give away the dongle with the sim without deleting/closing my account. Does anyone know how to delete/close the account?

Any advice would be greatly appreciated.

Many thanks!
