My device won't connect to the Verizon network. How do I fix this?

is there any way to reactivate current sim card

Try this:  turn off the phone, remove the SIM card (be careful not to touch the gold contacts), wait a few minutes, then reinsert the SIM card, turn the phone back on, and give it a few minutes to re-establish a fresh connection to the network.  If that doesn't work, try a new SIM card; they're free at your local Corporate Verizon store.
