This set, while in needed NONE of the accessories or other card adapters, was a PERFECT FIT!

Great fit for my tiny sim card.

If your sim is not an exact, absolute perfect fit, beware

Not a great fit, it will be needing considerable force to both install and remove with Sim adapters

So to see if the Sim Card, which is a Sprint/Nextel micro Sim Card, could work with the device regardless of service provider I pulled the Sim Card from my own smart phone and insert it into the adapter, but it no longer fit into the Sim Card slot

Great fit when the T-Mobile adapter didn't work.

Everything you need to switch between phones without stopping at your service provider to keep switching SIMs out for you!I'm not really sure what the little sandpaper bar is for - my guess is to smooth out little plastic burrs on the SIM card for a better fit.

Perfect fit.

I use t-mobile and the micro tiny sims card worked well and fit perfectly if not a little snug
