Just over a year ago (after
N*Star had migrated from EE to Vodafone) I picked up a new, sealed in box, Vodafone branded Huawei HHG2500 in an attempt to understand the problem of the Vodafone G.993.2 based service.
Of all the contents in the box, the only item I have kept is the PSU.
(It is used to power my Watchfront FB105, when I have a need to use that device.)
