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".

Title:
  Text for SIM status in the panel takes too much space and does not
  scale for multi-SIM

Status in Network Menu:
  Confirmed
Status in Ubuntu UX bugs:
  New

Bug description:
  When there is no signal, the indicator shows the text 'No signal'
  which takes up far too much space. It should use an icon, such an the
  network-offline icon from the system. This may be blocked by bug
  #1294251 as the network-offline icon is currently missing.
