What is the CoreESIM signal availability during the ascent of La Soufrière Volcano?

CoreESIM provides reliable signal at the trailhead and the initial lower elevations of La Soufrière Volcano. As hikers ascend into higher altitudes and denser vegetation, particularly nearing the crater rim, signal strength may become intermittent or susceptible to environmental factors like wind and atmospheric conditions. Expect reduced data throughput in these challenging terrains.
