It can, but both my Fairphone and old pixel could have a physical sim and an eSIM. I daily drive both with my old US number and my current EU number. Can’t have two active eSIM cards at once though

The term snake oil is actually especially fitting for this, due to its origins.

In Britain in the 1700s there was a somewhat common recommendation for using rattlesnake oil from the fat of the snake for skin diseases/rheumatism. The efficacy is debated but it’s got some amount of potential for change (if not help).

This turned into people in the US selling mineral oil as “snake oil” as a total panacea. So a product that actually could do stuff being used as the poster child for a completely useless product that can solve every issue ever, buy as much as you can today.

Snake oil indeed.
