How the recommendation works
The finder estimates your total data from how you use your phone (roughly 0.3GB/day light, 0.6GB/day medium, 1.2GB/day heavy), rounds up to the nearest common plan size, and suggests a marketplace that fits your destination. It's a starting point — if you tether a laptop or stream a lot, size up.
