How to get the best deal

  • • Compare price per GB, not just total price — a $10/5GB plan ($2/GB) beats a $5/1GB plan ($5/GB)
  • • Match duration to your trip — don't pay for 30 days if you're staying 7
  • • Consider top-up support — start with less data and add more if needed
  • • Check the network and fair-use terms — speeds vary by location, device, congestion, and roaming partner
