When traveling on the ferry between Hong Kong and Macau, your EastESIM will provide a strong signal while you are docked or very close to either port. However, as the ferry crosses the open waters of the Pearl River Estuary, the connection may become weaker or drop temporarily. Both Hong Kong (with carriers like CSL or SmarTone) and Macau (with CTM or SmarTone Macau) have excellent coastal coverage, but deep-sea conditions can impact mobile signals. Expect full connectivity to resume as you approach your destination's shore.
