Sim card cutter,
Amazon Verified Purchase(What is this?)
This review is from: LUPO NOOSY Nano Sim Card Cutter For iPhone 5 (SILVER) (Electronics)
This dual sim card cutter works perfectly well & easily cuts standard sim cards to micro size & micro to nano size. Just make sure the card is entered the correct way round & centralised in the slot before cutting thru..... it's not rocket science. I've cut several sims cards & each one has worked perfectly after installation.
