Is it cost-effective to use my home SIM for roaming in the Global South?

For most travelers heading to the Global South, relying on your home SIM for roaming can quickly become very expensive. Unlike some regions with 'Roam Like at Home' policies, many carriers charge premium rates for data, calls, and texts when you're in places like Brazil, Vietnam, or Kenya. These charges can add up surprisingly fast, turning your budget trip into a costly one. A SouthESIM is specifically designed to offer a much more affordable and predictable solution, keeping your travel budget happy!
