SouthESIMs are primarily designed for mobile data, giving you seamless internet access to power all your travel needs. While they don't typically come with a traditional phone number for direct calls or SMS, you can absolutely use data-based communication apps. Think WhatsApp, Viber, or Messenger – these allow you to make calls and send messages to anyone, anywhere, using your SouthESIM data. This is super convenient for coordinating with travel companions in Vietnam or calling home from Peru without extra costs.
