Hello
YES! I am currently using the Moto Z Droid Force with Straight Talk, Verizon sim Bring-Your-Own-Phone (BYOP). It works great. LTE speeds are limited to approx 5Mb/s. Calls, texts, streaming iHeartRadio, watching Netflix all works fine. Also, you will get security updates pushed to your phone. I got an update a few days ago for bug fixes and an android security update. (Software Version: MCL24.246-36. Call audio improvements; Latest Android™ security updates and bug fixes)
Most notably, the Advanced Calling, VoLTE feature will NOT work. This feature, amongst other things, allows users to make calls and surf the internet or use the internet for that matter. For example if your using your phone as a hotspot for your laptop and someone calls, you will have to drop the internet connection in order to talk on the phone, unless that feature is activated via MyVerizon App. Its possible that other Verizon specific feature won't work, but this is the only one that I was concerned with.
Wifi calling: I haven't tried using this feature. This may be another feature that needs to be activated via MyVerizon App on the phone in order to use it.
To activate you must have a new BYOP sim card from straight talk. You can order the sim from straighttalk.com, walmart.com or go into walmart. I believe if you buy it on the Walmart.com or StraightTalk.com sites you can get the sim for a dollar plus shipping. But if you got into Walmart they bundle the BYOP kit (includes sims for all carriers) but its $15 plus the plan you want ($45 plan or $55 plan). For example, if you want the $45 - 5 GB plan, its $59.99 for activation sim and 30 day plan. (I don't like to wait so I opted for the in-store kit)
