Fiddling with your mobile phone can sometimes make you stumble upon something most amazing. It can also yield you unexpected gains.

While playing around on a T-Mobile prepaid SIM on a spare phone with no active service, 17-year-old Jacob Ajit learnt to hack his way to getting free phone data.

Ajit told Motherboard: "Honestly, I just investigated this out of curiosity, and to learn a bit about how these networks are configured."
