Yep. Virgin uses EE which is generally rated as having the best 4G coverage. I’ve been using EE for a couple of years now. Though I believe many boaters have taken up the 3 unlimited data deal and are pleased with it. The point for me is that EE don’t currently do unlimited data so that’s why we have gone to Virgin.
My Buzzard 2 car WiFi 12v cig lighter device works with both EE and now on the Virgin unlimited deal. Though I’m lucky I wired the boat’s 12v cig sockets above the gunnels next to windows from what Tony has said!
Other options are available. But as of now only the 2 unlimited data deals. I need unlimited data as we stream all our telly (really could not be ars*d with putting up the aerial pole and retuning unless absolutely necessary).
Just letting you know what works for us FYI.
