A:Answer This isn’t really the place to ask general questions about technology, but I’ll provide an answer as it pertains to iPads.
ALL new iPads are unlocked. If a device is “locked,” it means that its cellular capability is tied to a specific cellular carrier, like AT&T, or Verizon, etc. But every new iPad that has cellular ability works with all carriers, generally, rather than just a specific carrier, so in that sense all new iPads are unlocked. But of course some iPads have cellular capability and some don’t. And, by the way, the phrase is “WiFi and unlocked,” not “WiFi unlocked.” The lock part and the WiFi part are two separate things.
In contrast, cell phones typically DO provide a choice between “locked” and “unlocked.” For example, you might buy an iPhone that is “locked” to AT&T, meaning that AT&T is the only carrier you can use with that phone. Of course instead a phone might be locked to Verizon, or T-Mobile, etc. When a phone is said to be “unlocked,” that means it is NOT limited to a specific carrier. It can work with all carriers.
