Cellular

If your iPad is a model with wifi and cellular capabilities, you can use

a wireless data plan for access where your wireless provider has signal.

If your iPad is wifi only, cellular capability cannot be added after purchase.

However, your wireless provider may offer a mifi-type device for portable connection.

Since this is a variation on hotspot, it may not meet your needs.

Hey there Zacthemann88!

Yes, you can buy a cellular model for your iPad. Sadly, if you have an iPad already that does not support Wi-Fi, than you will not be able to get it. All you have to do is get another SIM card. It only works with data, so you must get google voice or any alternative to text and call using you phone number.
