Yes, 100%! Opting for SouthESIM is significantly simpler than buying a physical local SIM card at Sofia (SOF) Airport. To get a local SIM from providers like A1, Yettel, or Vivacom, you typically need to locate a kiosk, wait in line, and go through a mandatory passport registration process as required by Bulgarian law. With SouthESIM, the entire process is digital, requires no ID checks, and can be set up from the comfort of your home before you even depart, letting you land connected and ready to explore.
