You have a MyProximus account, but can't view all your products (anymore)? Via the MyProximus website, add all your subscriptions and related bills or payment statements to your existing MyProximus account. This way, you benefit from all the services (e.g. Public Wi-Fi) and can also view all your products in the MyProximus app.
It is not possible to add a Pay&Go number. This is also the case if you have several bills per month with a different customer number.
In both cases, create as seperate MyProximus account.
