It is not possible to switch directly to a different product or rate plan (e.g. from yallo Home 4G to yallo Home Fiber). The existing product must first be canceled so that the new product can then be installed afresh.
We can offer advice as to which product best suits your needs and are happy to help with the switch. We are available by phone and via the chat tool.
