I just purchased an unlocked S20 FE, direct from Samsung. I have also been using Cricket Wireless for about 3 years now, with an unlocked S9 Plus. However, after putting my SIM card in the S20 FE, I received a message that the device is not compatible with their network. When I made a call to Cricket's customer service, I was told that there is nothing they can do to activate my new phone with their network. Even though Cricket offers the exact same phone for sale, through their website! It seems like Cricket is moving toward forcing their customers to purchase phones through them. Which is a shame, because that is going to force me to do business with a different wireless network.
