There are countless videos and blog posts telling you how you can take your full size SIM card and cut it down to fit in your iPad, but frankly, that’s idiotic. I mean really, who’s going to cut up the SIM card they’re using in their $85+ a month iPhone to put in their iPad when they could just pay $30 a month for unlimited date on the iPad. Yes, you might be cutting up a T-Mobile SIM, but let’s face it… Do you really want to be using EDGE on an iPad?
Anyhow, that’s not what this post is about. I’m going to show you how to do the exact opposite of that, how to take your Micro SIM and use it in your iPhone for cheap data only service. It’s easier than you might think.
Update: Some sites are incorrectly reporting that you need a jailbroken iPhone for this to work, you do not.
Update 2: You also watch this quick video walkthrough.
