I would've said no, but the bill shows otherwise. The usage I'm sure is 99% YouTube/Netflix which are ridiculously well optimised and deal with unstable connections very well. I don't think it's consistently bad, it's very intermittent.
Will be able to investigate more in a few weeks anyway.
As Netflix is included in Threes 'Go Binge' its almost certain that the 74Gb of Go Binge data shown in that bill is Netflix. Based on that bill, you would need at least 200Gb per month, and that basically means going 'unlimited'.
If its good enough for Netflix streaming, but its somewhat intermittent, then you could try the setting in the B535 to manually set it to 4G only, which might stop it dropping down to 3G at times. But it could mean that the internet will drop out completely if the 4G signal is rubbish. So worth also trying setting to 3G manually just to see what happens.
If its dropping down from 4G to 3G, then you may find that the Bunny Ear antennas will help to maintain the signal, but if the rubbish antenna from eBay didn't help, then it may be that the Bunny Ear antennae will be no better.
Try using the Android huaCtrl app to view the signal parameters when you change things to see what gets better/worse (remember that huaCtrl seems a bit temperamental so you may have to exit it and restart it). Alternatively, login to the router config pages and go to Advanced > System > Device Information and just refresh the page.
If the signal is decent enough, then your issue (like mine) may be an 'over subscribed' mast - not much you can do about that except a) watch Netflix at 5am when nobody else is online b) change mobile provider
You could try complaining to Three, but £17/month for unlimited data isn't really going to be offered to you at any cheaper price at this present time. But its quite likely that they will give you a £5-10 credit if you complain well enough. And you can complain every 4-6months and they'll keep crediting you £5-10 each time
(be prepared to spend anything from 20mins to 1+hours arguing your case with Customer Service clowns - probably not best use of anyones time really).
And you could also use this page:
https://www.three.co.uk/Discover/Network/Report-An-Issue/ to report a Signal Issue with their network. It's quite likely that they just ignore these reported issues, but just possibly they get clocked-up and help to push your local mast up the list for upgrade.
