I found out about an alternative to having a second phone for the hobby. I'm sure many already know but for the benefit of the ones who don't:
Buy a prepaid sim card (I use TMobile), it will cost as little as $10. Set the account under a fake name, they won't verify. I told them it was for a guy who was working for me and that I needed to stay in touch with him.
From that point it's just a matter of switching the sim cards on your phone. The obvious downside is that your real phone number will be off while you use the other one. If you have an old phone you can use it.
It works well for me because I don't use the phone a lot for hobbying.
