Yes you can. There are two ways to do this. The easiest way is to use the smartphone app and then select *98. This will connect you to the Interactive Voice Response (IVR) system where you are able to manage all of the functions. The second way is to dial an access number. When the call is answered you will be either identified automatically from your phone number or you will be asked to key in your account details. Once you are authenticated simply dial *98 and again you will be in the IVR system.
