Today, Apple held the launch for the new iPad and along with the launch, a few interesting tidbits were revealed that weren’t mention during the media event. One of the major selling points of the new Verizon iPad Wi-Fi + 4G LTE is its ability to connect with GSM networks for international roaming purposes.
However, what wasn’t made clear was whether users could insert an AT&T micro-SIM card into a Verizon iPad and use that to connect to the data network. Since the Verizon iPad supports the same GSM frequency bands for non-LTE networks as the version sold for AT&T, it was technically possible to use a Verizon iPad on AT&T although Apple could have restricted the device’s operation on other networks.
MacRumors points out that the new Verizon iPad does work with AT&T’s network when an AT&T micro-SIM is used and the device’s carrier settings are updated to support connecting to AT&T. The article also points out that the Verizon iPad will be limited to non-LTE bands (EDGE, 3G, HSPA+ 4G) on AT&T.
The Verizon iPad’s hardware supports the 700 MHz band for LTE to work with the carrier’s technology, while the GSM version sold for use on AT&T’s network supports both the 700 MHz and 2100 MHz bands as used by that carrier.
