It's trash, just turn it into an electronics recycler.
Alltel was bought out by Verizon about seven years back, and as a general rule, they don't reactivate Alltel phones on their network. This doesn't mean that an old Alltel handset grandfathered in from the buyout couldn't be used on Verizon after the buyout, but once the ESN was taken off of an account, there was no putting it back on. That's the problem with CDMA handsets by the way, they're primarily locked to the network they belong to and can't be taken elsewhere. Verizon and Sprint both have very strict no flashed/hacked phone ESN activation policies in place as well - not to mention that tampering with a phone's serial number (the ESN on CDMA phones and the IMEI on GSM phones) is illegal without consent of the manufacturer. The long-short of it is, unless the ESN is already in a CDMA carrier's database for approved activation, it can't be activated. Full stop. No Verizon or Sprint postpaid, prepaid, or MVNO is going to touch that fool thing with a ten foot pole for activation.
If you need a cheap handset and carrier with minimal usage, pick up a cheap, used 3G GSM capable feature phone that's carrier unlocked and pick up an H2O Wireless SIM card for the thing. Otherwise, read the guide linked in my sigline if you want more info and options.
