Can I use my SouthESIM to make traditional phone calls or send SMS messages?

Updated April 22, 2026

Most SouthESIM plans are designed specifically for data, giving you fast internet access wherever you go. While they don't typically include traditional call minutes or SMS texts, you're still totally covered! You can easily use popular apps like WhatsApp, Telegram, Facebook Messenger, or Skype for all your calling and messaging needs. These apps work seamlessly over your SouthESIM data, keeping you in touch with friends and family whether you're exploring Hanoi or the beaches of Rio de Janeiro.
