I just switched to T-Mobile from Verizon and still not sure if the dead zones are worth the cost savings and other perks. But I thought you couldn't use the same phone bc they're different types of networks - not that it's locked but that physically the phone can do either CDMA or GSM networks. I'm curious about your experience because I may need to switch back.
To add to this post, my phone is unlocked from BHphoto (reputable large online retailer). I've tried all the tricks in this post and my phone doesn't have the capability (per bixby as someone else had posted). If I had known I would've gone carrier specific. I hope someone else learns from this post!
