Even if "The shape of an SIM card is universal and recognizable", which I doubt, that is less likely in an indicator icon. The two things which distinguish a SIM card from just a rectangle are (a) the microchip, which would be covered or muddled by the X, and (b) the bevel, which would be miniscule at that scale. Having said that, Matthieu is experimenting with different SIM icons, which our usability researchers will test.
Meanwhile, they recently tested recognizability of various other indicator icons. Unfortunately the results aren't published yet, so you'll have to take my word for it, but two results were relevant here.
First, a rectangle with a cross in it, *next to* the normal signal icon, was tested as a possible way of communicating "No signal". Zero out of twelve participants recognized it. This is not quite what you are suggesting, and I don't have data on whether they guessed it was anything else, but I would be surprised if any of them guessed it had anything to do with the SIM.
Second, a padlock emblem in the corner of the signal icon was tested as a possible way of communicating "SIM locked". I don't have exact figures, but the research summary says "The lock made the indicator icon unintelligible". This was probably because the padlock was so tiny, but still covered too much of the signal icon to leave it recognizable.
Shruti Kapur and I are working on the multi-SIM case right now. But remember that someone might buy (or be given) a dual-SIM phone, but use it long-term with only a single SIM. In that case, it would be annoying for them to see either text *or* an icon meaning "No SIM".
