Unfortunately, free roaming is rarely a given in the Global South with your standard home SIM card, especially if you're traveling from the UK, US, or Europe. Countries in regions like Latin America and Southeast Asia are typically outside the 'free roaming' zones offered by most carriers. Sticking with your home SIM could lead to surprisingly high charges for data, calls, and texts. This is precisely why SouthESIM is such a budget-friendly alternative, connecting you to local networks in places like Peru or Vietnam without the hefty fees.
