Read this guide Guide: Cancelling Your Contract Info on STAC codes there
This has just got a LOT easier with the addition of STAC codes. To obtain a STAC code text STAC to 75075
You should then receive a text with your STAC (or depending on the network you may get a follow up text asking for security information). A STAC code consists of 6 numbers followed by three letters which identify the old network.
You should also be able to request a STAC code from your online account
Give the STAC code and the number you want to close to your new network and the old number should close down the following working day (if the code is given before 17:30 on a weekday) or within two working days if the code is given after the cut off or at a weekend. You can also choose for the old service to terminate on a date of your choosing
Under the new process your old supplier can no longer charge you a notice period for leaving and your old service will terminate automatically on the date arranged with the new network
