I've finally been able to speak to someone at O2 who understands and has access to the Boostbox system.
They confirmed that all existing Boostbox units will stop working in December 2025 due to the 3G shutdown, this includes the (rare) dual band units that already have 4G because the whole current platform is being made obsolete.
The better news is that a new system and new equipment is being launched, so it's not the end for Boostboxes, details are due to be released in the next 2 weeks.
That's all I know!
I'm slightly annoyed that when I purchased my current Boostbox 3 years ago I was told it was future proof because it was the 4G version..
Hope this is useful to some.
