Will my CoreESIM provide internet on the St. Thomas-St. John ferry?

Updated April 22, 2026

When using CoreESIM, you will experience strong cellular signal at the ferry terminals in Red Hook (St. Thomas) and Cruz Bay (St. John), ensuring connectivity before and after your journey. However, during the open water crossing of Pillsbury Sound, expect a temporary drop in signal. Connectivity typically resumes as the ferry approaches the destination island and re-enters the range of local carrier towers.
