Welcome to Vodafone Community
BT has just started a new combo whereas you get a usb modem to connect to their hub so to give resilience to your connectio if it were to fail connecting to the BT mobile network until the connection resumes.
Could it be that Vodafone has the same idea regarding their connection especially when people just get connected and the DLM gets underway ?
There's an extra usb socket on top of the router behind a hidden sliding cover. Even in the settings there's a 3G/4G settings for connecting a usb mobile data modem.
That could solve a lot of issues until they proactively try to fix a connection issue so that their customers are not left without any internet. Thoughts ?
