How can I use a htc pantech smartphone that has been cut off?

How can I use a htc pantech smartphone that has been cut off and a balance owed on the account? Buy a new sim card? How to use WIFI only? Google and the web? thanks?

Pay the balance and reactivate the phone or take it to a different carrier that uses GSM. (in the US that would be AT&T and T-Mobile)

Without a carrier the phone side of it and data outside of a wifi area is useless. But if you want to use it like a PDA then you'll need to root the phone. You can find instructions online for that.
