It is very limited. You will have reliable 4G/LTE coverage in the main towns (Roseau, Portsmouth) and at the cruise ship port. However, Dominica is a rugged, mountainous, and undeveloped "Nature Isle." Once you go deep into the rainforest (e.g., hiking to Boiling Lake, Trafalgar Falls, or on the Waitukubuli Trail), you must expect the signal to be intermittent or non-existent.
