The Golden Warning: Never Share on Metered Mobile Plans!
If your mobile contract has a 10 GB or 20 GB monthly cap, sharing bandwidth can trigger carrier overage fees of $10 to $15 per additional gigabyte. You would be trading $15 of carrier bills to earn $0.30 in passive rewards.
When to use Mobile Sharing: Only enable Pawns.app over cellular if you have a verified, truly uncapped "Unlimited Data" package with no fair-use throttle under 100 GB.
