At giffgaff, we think that you're the best person to manage your account so we are giving you tools to tweak it whenever you want. This article explains how to block specific type of calls to be made from or to your phone.
Controlling your services is a great way to make sure that you are not spending more than you intended to.
In order to check the status and modify any of the available call services, you first need to login.
You'll then be able to access the call services page. All the different services are described in the next section.
By default all the services are active, you can then chose to bar any of them by toggling the button from "OFF" (the barring is inactive on this service) to "ON" (the barring is active on this service).
Once you have changed the status of a service, it will take a few minutes to reflect on your phone.
You may notice that other services are being modified at the same time. This is because some services are linked together, and barring one makes the other inactive (see below).
Please note that you are only able to make 2 changes per day. Each time you toggle a service it will count as 1, so deactivating and then reactivating the same service will count as 2 changes.
