This answer is incorrect. While Simple Mobile (subsidiary of American Movil in Mexico and subsidiary of TracFone Wireless in the US) does utilize T-Mobile, a GSM based network, it also utilizes Verizon's CDMA 4G/LTE network. (TracFone itself subsidizes coverage from. T-Mobile, AT&T, Sprint & Verizon). So yes, Simple Mobile will most certainly work on a Verizon branded device. I am currently using a Simple Mobile prepaid plan on my Verizon branded Moto G4 Play (xt1609). Setup required a couple of APN edits but was otherwise extremely simple to initialize.
Moreover, all newer Verizon smartphones (which use 4G/LTE) are both CDMA & GSM. LTE is a GSM technology.
