Firmware version installed: 22.214.171.124.83.8.77 (type A)
As the BH3 is identical in hardware to Home Hub 3 (type A), it is no surprise it behaves similarly with regards to which ISPs are supported on ADSL with the BH3.
A list of known realms supported by Home Hub 2 can be found here. It is known the Home Hub 3 (type A) can be used on PlusNet (ISP owned by BT)
A randomly created PPP username and password entered as a test
The test was repeated for a randomly created PPP username in PlusNet realm. (BT own PlusNet)
Successfully saved, so there is a very good chance the BH3 can be used on PlusNet.
The following screenshots are a bit misleading as the BH3 was connected to a TalkTalk LLU connection, which accepts any PPP username & password.
