There might be different reasons to why there is no dial tone on your landline.

Firstly, confirm that there is power going into your telephone set, and if need be, try a different telephone set that you know works. If you still do not have a dial tone when using a different set, we suggest that you report your line by calling 133, where you can automatically report your landline issue, by leaving your landline number and mobile contact number where we could reach you.
