For their first batch of 4G LTE handsets, full-sized SIM cards are the key to accessing Verizon’s next-gen network, but that looks to be changing soon as Verizon will introduce microSIM for future devices. The first device to launch with the new standard will be the Samsung Galaxy Tab 10.1 4G LTE. Though in terms of network access there will be no difference between devices using a microSIM and those using a regular SIM, you won’t be able to swap the differently-sized cards between devices.
The leaked document detailing the new SIM cards isn’t clear on whether or not all future devices will operate with microSIM or if the Tab 10.1 is a special case. The document does state the the new-type SIMs will be introduced later this month, hinting that we might expect the Galaxy Tab 10.1 at that time as well.
