My wife has this phone and I had to use one of her bobby pins to push the sim card far enough in to 'click' it into place. You can use your fingernail to unclick it to get it out, but my fingernail wasnt strong enough to push it in far enough to get it back in.

I dont care much for this setup. Why they couldnt use the slide-in setup like they did on the w810 phone, I dont know.

Hope this helps. :)
