Samsung has apparently confirmed for AndroidCentral that their LTE version of the Samsung Galaxy Tab 10.1 will come with a microSIM card. This is in contrast to the Thunderbolt, Droid Charge and LG Revolution which use a full size SIM. Currently, you can pre-order the Samsung Galaxy 10.1 LTE from Verizon priced at $529 and $629 for the 16GB and 32GB versions respectively. There is no word on whether this will be a new switch to the microSIM standard, or if it is just a one-time blip for this device. Verizon intends to release their microSIM card later this month, but has not announced if the Galaxy Tab 10.1 LTE will release at the same time.
