Verizon still hasn't come forward and said exactly when its LTE-enabled Samsung Galaxy Tab 10.1 will be launching, but when the slate does arrive, it looks like it'll be the first device on Big Red's roster to use a micro-SIM (like the one in the GSM iPhone 4/iPad) rather than a more traditional mini-SIM. There won't be any differences between the two SIM cards save for their size, although that does mean that you won't be able to use a micro-SIM in a device that normally takes mini-SIMs, and vice versa. There are adapters available to turn a micro-SIM into a mini-SIM, though, so that could be an option for folks that plan to do a lot of SIM switching. Also, as you can see in the image above, it sounds like Verizon is planning to use micro-SIMs in most, if not all, of its LTE products from 2012 on.
Considering how the trend nowadays is to make devices as thin as possible, it's not much of a surprise to see that Verizon would like to transition to micro-SIMs to help shrink its devices even further. This is especially so when you remember how chunky the first batch of LTE products were, at least compared to the thinner 3G-only devices (iPhone 4, Galaxy S II) that've been coming to market as of late. The switch to micro-SIMs may not mean much to the majority of Verizon customers, but hey, it's always good to know what's powering our beloved devices, right?
