Up to about 3 weeks ago, I had a Motorola Moto X running Android 5.1 with Verizon/CDMA . Then I switched to a Nexus 5 running Android 6 with Ting/GSM. The Ting service is terrible it turns out, so I am probably going to switch back to Verizon. I do like the Nexus 5 much better than the Moto X. Can I use the CDMA SIM Card from the Moto X in the Nexus 5 on my switch back to Verizon?
