If you want to use HTTP without load and still can go for a no buff 720p60.
First, turn on the http injector's config,
Second, turn on the postern's vpn.
Wait for the http injector's notification that it's injected or connected, and done.
P.s this will share the same problem with postern (5mb data capping) but still the download speed is high (depends on your location and ehi and prx.)
