The weep holes are part of the drain assembly that allow trapped moisture that gets through the tile and grout into the mortar bed to go into the drain.

With the drain strainer removed, you should be able to see three small holes on the top half of the steel sleeve that is the inner drain pipe.

It is common for the weeps to get clogged during construction or over time.
If they are not clear, the entire mortar bed under the shower floor will become permanently wet and gross.

Let me know if I can help.
Maybe I have a picture.
