OK, maybe not a pukka fix but the same thing happened to me while on holiday. Samsung Nexus snapped Sim pin due to an adapter hooking on the pins. Solution: tin foil from a Rolo, made into a small plug that just fits into the slot over the pin. Hold it in place with a needle from a hotel sewing kit. Slide SIM card in over the tin foil. Been using the phone like this for the past three weeks. Writing this reply on the self same phone. Jerry-rigged perhaps, but a fix nonetheless.
