AT&T or Verizon.
If you decide on an iPad with Wi-Fi + 4G, be sure to select the model that corresponds with the carrier you’d like to use for 4G LTE service. The iPad model you purchase is specially configured to work with either AT&T or Verizon — not both. So while you don’t have to activate service right away, you should choose your iPad with Wi-Fi + 4G according to the carrier you prefer.
Ready to take on the world.
The new iPad offers the most comprehensive support for fast networks around the world. It’s designed with two cellular antennas tuned to 12 different bands that access a larger frequency spectrum. That means you can travel almost anywhere in the world and get online. And your connection is always fast. iPad with Wi-Fi + 4G models for AT&T and for Verizon connect to GSM/UMTS networks worldwide. But if you want a local connection when you’re traveling, just pop in a local SIM card.
隻有用4G LTE service才需要選擇AT&T or Verizon。在其他國家如果不用4G LTE service則隻要插任何local SIM card即可上網。其他國家如果有4G LTE service如何辦不清楚。
