How can I text all my phone contacts on my iPad Air?

[iOS Gravity]

Unless they have an iOS device, you can't text them from the iPad.

Since from an iPad you can only iMessage another that has an IOS device determine who does in your contacts and make a group and iMessage them, The rest of them that don't you can email them as a group if you want.

You can also download an app such as Group Me or something similar. Other than that, the previous comments are correct...your contacts must have an iOS device
