I have B310s-22, I don’t know how it differs from B310s, but the web interface from 310 got up fine. I took it for a summer residence, to distribute the Internet, because I didn’t want to use the phone, and the whistle at a very slightly lower price is not so convenient and functional. Modified web interface opened additional settings (for example, connect only via LTE) There is a jack for the phone, but I checked, I can’t find the cables. ( I recommend.
