been collecting sims along my travels through asia and it sucks to think that i won’t be able to use my ipad on return trips. supposedly you can simply cut down the chip to 12mm x 15mm. i guess we’ll see…
the preliminary image used drawing the template. at&t’s image doesn’t match the stated spec size of 15mm x 12mm.
the template for laser cutting. black lines for scoring a positioning guide and the magenta line to cut. i can post the .dwg after i verify that the crop will actually run in an ipad.
the first line for cutting a template to place the sim card.
the second line for cutting the micro sim.
the cut micro sims.
UPDATE 04.30.10
the fit micro sim. a bit of a gap on the diagonal cut, otherwise a perfect fit. i can post the template after i find time to edit the dwg.
the contact side. a bit tight and unfortunately i won’t be able to test the cut sim as we’ve recently rerouted our trip around bangkok. my only question is how to recharge a prepaid sim if you don’t have a dialer? waiting for a the next iphone to do that would really suck.

That’s magical work. Do you think the AT&T picture of their micro sim is just not to scale or have they created a “non standard” micro sim to really screw us over?
Where do you get a laser cutter, or are there any shops offering the service ?
not sure why the drawing is not to scale.
i borrowed a friend’s laser cutter.
There seems to be already an adapter that does just this: http://www.microsimadapter.com
the microsim adapters are now available at microsim-shop.com

Hey, so what’s the verdict? Do your laser cut micro SIMs work in the iPad? (Awesome post btw!)
mac,
i will test the template once the 3g version has been released.
The images on micosimadapter.com are being used without my consent and the template used has not been tested.

Thanks

Hi,
I found a good seller for Micro Sim Adapters: http://www.microsimdiscount.com – they ship via airmail (for free) from the UK. I got my adapter today and quality is excellent.

I found these great guys – http://www.ihandystore.com
They are the only one seller of micro sim adapters in UK and I just get mine. I must say I didn’t thought it would be so cool, it’s just what I was needed, it does the trick and I think I saved a lot of money with that thing. They also offer these cool looking skins called iDecal case, I think I’m gona try it out, it should give my iPhone 4 a great individual look.
Be sure to check them out these guys can be trusted.
