Can I pair any other cellphone with iPad mini

Pair how? Wifi should work to provide internet connectivity but not

for file transfer. Not all phones and/or wireless carriers provide

hotspot ability, and many carriers charge extra for it.

Bluetooth in iOS does not support file transfer. There

are some apps that claim to provide limited bluetooth transfers, but

I cannot state those claims are accurate as I do not use the apps.

Give them a try yourself to see if they meet your need.

No, for the most part pairing is not supported.

If your phone has the Hotspot ability to share its internet, you may be able to connect to it, either thorugh Wifi ro directly through bluetooth, but its not really pairing.

What exactly do you want to do by pairing them?
