Adapt a micro SIM card for use in a standard SIM card slot.
SIM cards are rather standard in size, so I was surprised that this was an bit of a loose fit (my micro card could wiggle about inside of it), and the result was a bit thicker than a standard SIM, but it did fit, and it's pretty goof-proof to use. Since my SIM was one of those "pop-outs" that could fit standard/micro/nano, I ended up using the outer pop-out for a better fit, but your own mileage may vary. Overall, it was worth trying for me, and I'd recommend it if you need.
Best price and arrived in a hurry! Would definitely order from again.
