We strongly advise scanning and installing your SouthESIM while you're still at home, before your flight departs. This way, your eSIM profile is all set up and ready. The moment your plane touches down at your destination, perhaps Phnom Penh International Airport (PNH) or Quito Mariscal Sucre Airport (UIO), you can activate your SouthESIM and have instant data. No need to stress about finding Wi-Fi or local SIM cards right after a long journey!
