A:Answer I bought three of these phones to use on Boost and they told me the Moto G5 Plus was not compatible with their network, and refused to activate them. Afterwards, since I had bought SIM cards, and they are the same network as Sprint, I visited two Sprint stores and was told these phones were NOT compatible, and also came up in their system as such. I am puzzled to see how anyone is using these phones on either Sprint or Boost.
