I'm from East Brunswick. After the storm, I also noticed that there was little to no Sprint service while VZW had coverage everywhere. I was successfully able to roam and send texts while roaming (although it may have taken a few tries), but while on Sprint, I was unable to receive or send texts or make or receive calls.
While roaming, I cannot make outgoing calls because I get the "Pay with Credit Card" message that someone posted in a previous reply. I can receive calls while roaming.
In Central Jersey, at least, Sprint took quite a hit. It still isn't back up in full. (Then again, my house still doesn't have power. It's Friday 11/2 at 11am when I'm posting this)
Stay warm, guys!
