When exploring Moldova's incredible underground wine cities like Cricova or Milestii Mici, expect your SouthESIM signal to be strongest at the entrances and visitor centers. Due to the sheer depth of these tunnels, sometimes reaching 80 meters below ground, mobile signal typically diminishes or is lost deep inside the cellars. However, you'll have full 4G speed when you're above ground, allowing you to share those amazing wine-tasting photos before or after your subterranean adventure!
