I went to the Mint Mobile help section chat room and asked what the deal was. They wrote...
"Mint Mobile does not support the Netflix platform".
When I told them that was some communist China BS they told me it was my phone, poor connection, website down etc.
When I turn on the free VPN Add-on provided by Firefox, Netflix loaded no problem. Turn off the VPN, no Netflix.
After I demanded to speak to a supervisor I got Netflix on my phone but not through my phone's Wifi hotspot unles the Netflix stream is routed through a VPN.
I wrote a complaint to the FCC and I am awaiting a reply but suspect this type of censorship is allowed. Silicon valley has become the new Office of Propoganda once thought dead along with the Soviet Union.
