    Just beware that if the post office is slow in returning the router, under the money back guarantee, then you will be receiving almost hourly phone calls from the collections department. There is nothing you can do to stop this (I was told before hand that if I called with the barcode from the return receipt that would be enough - its not, only the router in their hands counts). This might sound minor, but it took the post office 2 months to return the router and during that time I was flagged as a debtor requiring hourly calls.

    Utterly useless. Utterly utterly useless. If you have any opportunity to use anything else - do it.

    Practically useless.
    Intermittent connection that rarely exceeds 0.1mbps between 6am and midnight.
    Customer service is so bad, I could only call it hostile.
    I consider Threes sale of the package to be entirely fraudulent.

    Very poor srvice works sometime then nothing for hrs. would not waste time or money using 3 mobile broadband. Support is a waste of time they just blame number of people using it. HELLOI thought thats what people pay Broadband for to use not look at. You spend hrs on hold on the phone and get no where with them.

    absolutely horrific customer service! I've been having issues with my mobile broadband and Three simply refuses to take responsibility for it and they want to charge me loads of money to cancel the contract. I'm now making a complaint to the Communication Ombudsman Service.

    If I could give no stars I would! Shocking speeds and even worse customer service.

    I live in Sheffield city centre and don’t have access to fibre broadband, so the fastest speed any provider can guarantee is 6 mbps which is fairly slow. I saw that Three were claiming much faster speeds so decided to give it a go! Oh how I wish I’d read the reviews beforehand..

    It worked straight away out of the box which is about the only good thing. The speed fluctuated between fairly quick and unusably slow almost every 5 minutes. Tried the router all over the house to no avail. After a while, it settled on about 0.7 mbps which it never really changed from, despite showing full signal and 4G.

    I purchased this in the Three store which doesn’t offer the same returns guarantee as online, however the store manager agreed to honour the 30 days and authorised it in my contract in case I changed my mind, and with lockdown looming (and closed shops) I was told I would be able to cancel on the phone.

    This is where it gets even worse.. after being pinged around from pillar to post between various departments, I was told on the phone that they can’t authorise returns on the phone for products bought in store, and only the technical team would be able to do this based on the dreadful speed. After finally getting through to the technical team, they said I would only even be considered for a refund once they had conducted a weeklong troubleshooting investigation, and if the outcome of that was that they didn’t agree with my issues, there would be no refund. Feeling untold levels of dispair and betrayal about having been lied to in order to get me signed up in the shop (which had now closed because of lockdown), I opened a complaint in the online chat. After royally kicking off, the agent managed to honour my cancellation despite making a big song and dance about how it was outside of process and they were only making the exception as a goodwill gesture.

    Moral of the story.. DON’T BE SUCKED IN BY THE PROPOSED SPEEDS! Like most of these reviewers’ experiences, mine was dreadful. The customer service is abysmal too.

    Three when it works is great... just its not very often these days.

    For multiple years I have had long periods where text messages don't arrive... they just disappear, even when the sender is standing right next to me. Ive complained about this multiple times both to tech support and in shops, and am fobbed off with its "phone settings"... four different phones, two different operating systems... come on... three buggered up the white pages entry when my number was ported to three a decade back, and its been broken ever since.

    Worse, right now I am working from hme, using three mobile as my only way to contact office and data, and constantly see reports saying that three are upgrading my data connection and to expect faster speeds... but this is not the case. while "working" on the network I see data speeds slower than when I was using a dialup modem in the early 90's, and in the evenings it gets slower each week.

    I am fed up with being fobbed off by callcentre chimps, and even getting through to the second line tech support fairs no better. I spent 10 years lecturing in RF and digital communications technology. The last thing I need is yet another idiot insisting I perform a factory reset. I shall be leaving three.
