IPad pro only wifi without SIM but still same fetures but you can go for both wifi and sim would be better.
iPad Pro has whopping-for-Apple 4 GB of memory, the 9.7-inch version has only the same 2 GB as the previous generation Air. For a variety of reasons, iOS is nowhere nearly as memory dependent as some other platforms.
What’s especially clever, though, is the new True Tone system. It uses two ambient light sensors to detect the color temperature of the environment around you, and then adjusts the iPad Pro’s display to match that temperature, making whites look really, naturally, white.
On the 9.7-inch iPad Pro, like the iPhones 6s and SE, the M9 also allows for "Hey Siri! " unplugged — that’s full, hands–free, voice control. While it may seem like more of an iPhone feature, being able to use it with an iPad in the kitchen, for example, is aces.
Storage starts at 32 GB, like the bigger Pro, with 128 GB for those who want to step up. If you’d rather leap up, though, there’s now a 256 GB option for both versions. That way you can really take everything with you on the go.
Best camera with isight and 4k videos!
