One of the major selling features of the new Verizon iPad Wi-Fi + 4G LTE is its compatibility with GSM networks for international roaming purposes. But what hasn't been clear is whether users could insert an AT&T micro-SIM card into a Verizon iPad and receive data connectivity. Given that the Verizon iPad supports the same GSM frequency bands for non-LTE networks as the version sold for AT&T, it appeared to be technically possible to use a Verizon iPad on AT&T although Apple could have opted to restrict the device's operation on other networks.
Watch on YouTubeAs noted by jsnuff1 in our forums, the new Verizon iPad does indeed work on AT&T's network when equipped with an AT&T micro-SIM and the device's carrier settings are updated to support connecting to AT&T.
Big question on everyone's mind buying the Verizon iPad was whether data from AT&Ts 3G network would work on this iPad, or if Verizon/Apple would block this.
I was one of the first to obtain a Verizon iPad and can happily confirm that this is allowed! I used my ATT iPhone 4S sim card and took out the Verizon sim, and data worked! You must apply the AT&T APN carrier settings before this works though.
It is important to note, however, that a Verizon iPad will be limited to non-LTE bands (EDGE, 3G, HSPA+ 4G) on AT&T. The Verizon iPad hardware supports only the 700 MHz band for LTE to match 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.
Initial pre-orders of the new iPad are arriving today, while retail outlets in ten countries are offering in-store purchase for those still looking to purchase an iPad on launch day.
