It's all in the title! I just wanted to have your thought on this. Obviously it would help simplify the design, the waterproofing, it would be more ecological, etc. But more than that, it would be considerably easier for users to switch between carriers. I'm not in favor of removing things like the headphone jack, as it is still relevant nowadays (but in 2 to 3 years with USB C audio developing, it might not be the case). That being said, I can't find any advantages to keep this old tech that is the SIM card.
