February 10th, 2010 | Laser cutting micro sims



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.

  4. 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?

  5. Where do you get a laser cutter, or are there any shops offering the service ?

  11. mac,
    i will test the template once the 3g version has been released.

  21. 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.

  23. 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.
