Newegg, Amazon, Radio Shack, Walmart, probably others are all WIREFLY. They use Wirefly's parent company Simplexity. Read it in the fine print. The policies are all the same. I too am looking for a loophole to switch lines. Just looks like a high risk, and if they say you violated the terms they can directly ding your credit card. Al you can do is argue with a voice on the phone.
