Will my SouthESIM have signal on scenic coastal drives, such as in the Philippines or along Brazil's coast?

You'll generally find good coverage along popular coastal routes, for instance, driving through Palawan in the Philippines or along Brazil's Costa Verde. However, like with any mobile service, expect occasional brief 'dead zones' when passing through tunnels, deep coves, or very remote stretches of coastline. We suggest downloading offline maps and any essential travel info beforehand, just in case, ensuring you stay on track and connected for most of your journey.
