Verizon and Sprint networks use a different technology, called CDMA, which is not compatible with GSM phones. > In 2004, Motorola built success on the back of the Razr, a thin flip phone that became hugely popular around the world. Now, the brand, which is owned by Lenovo, is best known for its excellent budget smartphones, like the Moto G6, and phones with modules that attach magnetically to the back. Motorola's Moto Z3 became the first phone to promise (eventual) 5G capability, through a magnetic attachment, that will be compatible with Verizon's future 5G network.
