The other day I was updating something and a test failed. I looked at it and saw I had written it, and left a comment that said like “{Coworker} says this test case is important”. Welp. He was right. Was a subtle wrong that could’ve gone out to customers, but the wrong stayed just on my local thanks to that test.
I imagine you’d either have no phone, or one of those prepaid with cash ones. You could also probably turn off the cell parts and only use wifi
