There have been a number of posts on here from people (and I have absolutely no reason to doubt them), claiming to have indeed been sent a dongle, some say it was unlimited data, others that it was 100 Gbytes a month.
Equally, there have been post from people claiming they have been promised same, but it has never shown up. So who can say?

* Oh and just in case, please let’s not have another repetition of the cliched ‘all of our CS staff are trained to the same high level’, and you know who you are who said that. Because if you do, then, I promise, I may well bother to produce an entire list of threads, pointing out the falsity of your statement. Well unless, by the ‘same high standards’, you mean, equally incompetent (used in the literal definition) or not trained at all - which would be fair enough, and completely understandable and fit in with experience!
