I connected my phone to my laptop and turned on USB tethering and removed all my sims from my phone, but it was still showing upload and download values and some torrents were downloading and uploading. How is this possible if I have 0 internet? I mean, my phone wasn't connected to wifi and my laptop was still getting internet. Somewhat weird I think? What are the possible explanations here?

If there are no possible explanations, can I declare this a miracle and myself GOD!? :)
