How to Make a DIY Micro SIM to SIM Adapter

We've shown you how to turn a regular SIM into a Micro SIM, but what if you want to do things the other way around? Here's how to turn a Micro SIM into a regular-sized SIM card.

You'll simply take a regular SIM card and trace it onto an old gift card, credit card, or other piece of hard plastic. After you cut out the shape, you'll need to figure out where your Micro SIM would have to sit inside that in order for its contacts to be in the same spot on those of the regular SIM.

Then you'll cut and trace a hole, slip in your Micro SIM, slap some tape onto the back so that it doesn't fall out, and tada! You've made yourself a Micro-SIM-to-SIM adapter.

If you want to use this adapter in order to turn your iPhone 3G or iPhone 3GS into a data-only device by using your iPad 3G's Micro SIM, you'll have to change some carrier settings, but that'll only take you a few taps. [Hijinks Inc—Thanks, Aaron!]

AT&T Selling Micro SIM with Full SIM Adapter? (Update: Don't Think So)

The iPad 3G may require a micro SIM—a lilliputian SIM card incompatible with anything else you own—but AT&T will be selling each bundled with a full SIM card adapter—meaning you could potentially use your data plan elsewhere. UPDATE:

UPDATE: Actually, a better look from BGR shows us that this seems to be a punch out scenario in which you can't reuse the larger SIM casing once you choose to break away the Micro SIM. It's probably just going to make stocking at AT&T easier. Luckily, given that SIM and Micro SIM have the same contacts, adapters (even homemade ones) are likely to be available soon.
