another question about removing epoxy

[Dan Gahlinger]

I read the recent things about removing epoxy or other stuff gunked on components.

I have two questions,

I have an item with this stuff on it and I want to get it off,
however, some of it is covering some of the chips, and I need to be able to identify the components.

another worse problem is that one part of the circuit has a SIM card,
which is also covered in white epoxy which I want to remove without damaging the SIM card.

now the SIM card being encased in plastic means this is a whole lot of "fun"

any suggestions?
