Using a standard SIM card in your GSM (and some CDMA) BlackBerry is pretty easy to grasp at this point. Most come pre-installed if you buy your device from a carrier store, and even if it isn't, getting it in your phone is pretty straight forward. If you're like me however, you might have a micro SIM you want to use in your BlackBerry (I often use both an iPhone 4 / Bold 9900 and swap SIMs between them) it can be a bit more tricky.

Going forward to BlackBerry 10, the micro SIM will most likely be the card of choice for phones as we've seen in the BlackBerry 10 Dev Alpha already. If you want to use a micro SIM in your current BlackBerry however, you'll need to either pick one up from your carrier or cut down your current SIM (which I don't recommend). You'll then need to purchase a micro SIM adapter. Read on and we'll take a look at how to use a micro SIM card in your BlackBerry smartphone.

One of the first videos I ever did up for CrackBerry.com was a BlackBerry 101 on How to Install the MicroSD Card into your BlackBerry Smartphone. To this day it is still one of the most popular articles viewed on CrackBerry.com though back in October 2007 there were only a few BlackBerry device models on the market that actually accepted a MicroSD card. We're into 2010 now so I figured it was time to do a little update covering both MicroSD card installation and SIM card installation.

Warning: I did this video one take, no excuses. It's a bit long and tedious (I like vids to be 3 or 4 mins tops but dang there are a lot of BlackBerrys on the market these days), but seriously...I did a few extra takes and they weren't any better. But at least this way you can follow the trials and triumphs as I walk through the BlackBerry lineup starting with the Bold 9700 and going down the line to earlier devices. Since this topic of video has helped sooo many people over the years, I'll be sure to follow up in the months ahead with some shorter / concise by device model clips. In the meantime, enjoy the show. :)
