Is a 2FF SIM card SMT solderable?

    Curious if a 2FF SIM can be surface-mount soldered. Wonder if anyone has tried this. Is the plastic a low-temperature type that would melt with hot air?

    I would guess they aren't, as the plastic would probably melt. Why would you want to solder one anyway? If you're building a circuit to read one, it's better to use a SIM card socket. Molex makes them, Digikey or Mouser should have them.

    Curious about soldering because if they are soldered, they a) can't be removed, and b) the SIM supplier I contacted can't provide embedded SIMs.

    You can even get them on eBay for $1 including freight.

    Given that SIM cards can and do fail, I wouldn't solder one into a circuit even if I never intended to remove it. Also, what if I want to change provider?
