I am looking for a replacement "dongle" and thought that this looked a decent buy :-
Does anyone have any experience of that particular make and model please ?
It is a rechargeable battery unit but I would put a data SIM from Three into it.
Having screwed up the battery on my mobile due to excessive hotspotting during Covid, it is worth thirty-odd quid to avoid repeating the error.
Just asked on here as, whilst not an O2 question, there is a good chance of getting sensible and constructive guidance on here !
