4.0 out of 5 stars Beware sim cards come in all shapes in sizes, 30 Jun 2011
Verified Purchase(What is this?)
This review is from: LUPO Micro Sim Card Cutter & 2 Adapters - For iPhone 4, 4S & iPad (SILVER) (Electronics)
This product is fantastic, but for those purchasing it, there are a few things to know.

Whilst it seems as easy as inserting your simcard and then punching a hole into it make sure you take into account a few things.

1. The orientation of the sim card. When looking at the bottom of the unit, you should see the sim card chip and the rectangular side should be the side you insert first.

2. Sim cards come in all shapes and non-standard sizes.

I punched 3 chips and found:

o2 - is what I would call a standard sized sim, but has a large gold chip area. When punching this, there was absolutely no clearance on either side of the chip. If I had positioned even .001 of a mm left or right, I would have destroyed the chip. (Will upload a picture of all chips to demonstate). Luckily this was my test chip.

Three - Slightly smaller sim card chip and a lot more plastic on one edge than the other (instead of being equal plastic on each side. When inserting into the cutter, it's clear that the sim chip is not centered and cutting will cut through the chip itself. I used some scissors to get rid of a strip of excess plastic on one side, before putting into the cutter. Making sure that I created a border of plastic around the gold chip when cutting. ALWAYS leave some clearance and cut chips with the cutter upside down, so you can always see exactly what will be the end result in the case that the sim card moves. This was my PAYG chip and had 15 on it, so I was very happy it made it.

T-Mobile - This was a strange sim card. The Gold sim chip was actually rectangular instead of square which on the other hand left a lot more clearance on either side of the sim chip. This was the easiest to cut. This was my Pay Monthly chip and I was glad it was so easy to cut because T-Mobile charge for replacements.

So 3 cuts, all resulted in working sim cards. The result of which fit perfectly snug in the 2 black adapters that are provided which are made from a thin black plastic similar to Sony Memory Pro Duo camera cards (remember them?)

In all, I couldn't have wished for a better product and it will be with my on my travels.

Thank you darkspark88. Have just cut my test sim and dismayed with the result. I intended taking the scissors to the next one before I cut it and then read your review which says that is exactly what I should do. I have dug out some old sims which are no longer functioning to practice on, will then have a go with a PAYG with a couple of quid on before attempting my pay monthly Virgin sim which is destined for an I phone so I am a bit jittery. Your post very helpful. My only concern that when looking at other sim cutters it is almost as if the cutter on this one is the wrong way round, it certainly differs from the picture in the instructions contained within the pack
