I've had troubles porting my phone with a custom rom. Customer Service directed me to a stock rom with I've installed correctly and activated the phone. The problem is that stock rom had a security feature embedded in it which as locked out my wifi and usb. Ting refuses to take any responsibility, even though they directed me to the rom. Additionally by their own admission there is no warning not to activate with a custom rom. Ting screwed me and they aren't going to warn anyone else so they can screw them too. I've taken my phone to a couple of local shops and the original carrier, plus talked with the manufacturer. Everyone says I need a phone. With a new phone in hand, I'm out of here. Ting you're done screwing me.
Ting customer service is horrible - If you have a custom rom, just port away.
