I apparently cut down and ruined 3 of my foreign SIM cards trying to cut them down to fit in the iPhone 5.

I used this guide and I don't know what I did wrong but the phone displays NO SIM when I insert the SIM cards.

I used the guides from here:

http://www.ihackintosh.com/2012/09/how-to-convert-mini-micro-sim-in-to-nano-sim-for-iphone-5/
http://www.airportal.de/nanosim/

In the guide it says to print the PDF 100% on A4 sized paper. I only have an 8.5 x 11 printer. Is that where I messed up? Is the scaling off because I printed on 8.5 x 11 paper?

How long did you wait? It takes a good 3 to 5 minutes to register the new sim.

Also, did you mess with the thickness? I have done 2 out of 2 sim cuts successfully without a guide and never had to reduce the thickness.

Just hold a nanosim up to your microsim, line up the connections (lines, or dot at the bottom), mark with pencil, cut with scissors or box cutter.

It's actually really easy. I've cut 4 sims down to fit the iPhone 5 just free handing it with no guides whatsoever. Just cut it right up to the metal, and then cut the corner notch.

This is the first I've heard of this. I personally cut my SIM using the exact same PDF (even cut it a tad too small:eek:) and it works fine. Did you slice the chip in the middle?

That's what I did wrong. I cut part of the medal. I used the guide and it must have scaled wrong so I cut too much off.

I nicked some of the medal off around the outer edges, I didn't cut the chip in the middle. When you printed the guide did you print 100% on 8.5" x 11" paper?

That's your problem. For future reference, A4 is standard 8.5x11 paper.
A4 is 8.27x11.69
8.5x11 is US letter size.

You don't have to print on A4, just use letter 8.5x11 and print at 100%. It should be very obvious whether the scale is correct when you put your SIM on top of the printout. It should match 100%. I have done this on a foreign SIM and it worked perfectly. Although on the 2nd iPhone5 I had to push it down a bit to be recognized.

That's it then, when I lined up on the guys it was a little off. :(

I'm going to pick up another T-Mobile SIM and try again. :-(

Don't laugh at my cutting skills. The scissors were a little dull. :p

The one of the left is the AT&T Nano SIM and the one of the right is the one I cut.

No, it's not. It's similar in size, but it is NOT the same size, and you could very well have had slight scaling problems if you printed with 'scale to fit' on.

A4 is 8.27"x11.69" So it is both skinnier and taller than 8.5x11 paper.

I inserted the T-Mobile SIM I cut and let it sit for 5 minutes. It still says no SIM so it must be ruined. My iPhone 5 is 100% for sure unlocked.

This^^^
But use a REALLY sharp and sturdy scissors or exacto blade/box cutter.
If you look at my photo you can see I cut some of the metal. That's what I did wrong. :(

At the iPhone hacks section.
Look at my photo and don't do what I did!!! :p
Lol :D
Thanks bro, I learned from your example and was able to cut it right.
Just to test out my iphone 5 unlock. I bought a 99 cent simple mobile sim that runs on Tmobiles network.
After 10-15 seconds that said no service then the simple mobile logo came on the top left corner.

Your cut is wrong, you've cut too much off the right edge and not enough off the the left.

I cut this one successfully, pic before cut showing marking lines

Cutting through the metal isn't necessarily a problem. For some SIMs it's even necessary.

Anyway, when you put a SIM in, it should be immediately recognised. If it says 'No SIM', it will never be recognised because you did it wrong. It may take a while for a correctly cut SIM to register with the network, but during that time it will say 'No Service'.

Oh, and get yourself some real A4 paper. It's wonderful in so many ways.

Why don't you guys buy a $10 nano sim cutter from ebay.
Cheaper and faster to do it yourself.

It really isn't hard at all. Just put the scissors over the card and squeeze.

Most of us don't need our hands held that much for DIY related things.
