We suggest installing your SouthESIM before your flight. However, it's usually best to activate the data line only once you've landed at your destination airport, like Jorge Chávez International Airport (LIM) in Lima or Suvarnabhumi Airport (BKK) in Bangkok. Most major airports offer free Wi-Fi, which can be helpful for the final setup if needed. Having your SouthESIM ready means you can immediately use maps, book a ride, or message loved ones the moment you touch down, without scrambling for a local SIM.
