I’ve still got emotional scars from dealing with Vodafone over those SureSignal boosters. When you got them setup send working they were great, but they were finicky with internet connections…
For a long time in Suffolk I used bonded 4G connections (from a antenna on my mast on my chimney to sniff signal to the nearest mast) and flip flopping from one CGNAT to another could cause the S/Signals to go into a tail spin as the mothership hadn’t white listed the IP range - this necessitated a long winded support call, where you eventually got through to someone who knew what to do.
Then there was the V3 overheating / catching fire (luckily none of mine) but it happened to
other folks.I had acquaintances on another forum at the time drilling holes in the v3 units, like some weird swiss cheese, so they didn’t overheat and die and/or catch fire.
WiFi Calling. It’s a doddle in comparison.
