A:AnswerIt means the iPad is also equipped with a cellular data modem that can be used on cellular data networks provided by cellular carriers (like a smart phone, but only data... no “voice” plan), but the iPad is not “locked” to a specific carrier when you buy it.
A:AnswerIf the iPad is WiFi + Cellular it uses a Nano-SIM card slot. It also supports eSIM. The iPad 8th gen also has an embedded Apple SIM that is built into the iPad. Check with your carrier for compatibility and plan availability.
A:AnswerThe 3 colors are for the 8th generation iPad that Apple is making. The higher end iPad Air is the one that comes in multiple colors and should be available this month
A:AnswerFirst, there are two versions of every single IPad, a Wifi only version and a cellular service compatible version. The wifi only version is always cheaper but you can never add a data plan to it. A cellular service compatible version can be bought unlocked (which is usually more expensive, but you can pick your carrier and change carriers whenever you want), or tied to a cell phone carrier like At&T, Verizon, or Sprint, who will usually then give you a discount on the device, still not as cheap at the wifi only version but cheaper than unlocked
