SIM card from an old T-Mobile cell phone.

Package

Die carrier

Die

Size is approximately 2000 x 1340 μm (2.68 mm2).

Top layer

The mesh appears pretty weak: one serpentine line zigzagging back and forth with ~850 nm pitch (probably 400-500 nm lines, consistent with the ~180 nm technology node). Since it appears there's only one net there would be no penalty for shorting adjacent lines together, or for cutting out a sizeable area and bypassing it.

Next layer down

HF etched until mesh removal, but not imaged yet.
