How do I use my Verizon iPhone 4s on Net10 if my phone is compatible but it tells me the sim card I installed is from a carrier that is not supported under the activation policy?

i Traded my friend my galaxy for her iPhone and checked the compatibility for Net10 online. It said my phone would work and I even got it activated with net10 but when I put the SIM card in and reboot my phone it tells me the SIM card I have installed is from a carrier not supported by the activation policy....how is this happenning when the website told me my phone was compatible and no the phone was not jail broken
