We’ve had this‘service’ for just over a year now. We signed up in desperation as our BT cabinet is still not fibre enabled and the ADSL connection was awful.
It’s never been blazing fast, my jaw drops when people claim 200mbps. The last month it has just stopped providing any sort of service at all.
Customer service just talk me through a hard reboot of the router which achieves nothing.
Avoid like tile the plague.

As every one else has said this service is a disgrace. How can they be allowed to sell a product that doesn’t work surely this is illegal . This works fine in the middle of the the night but is completely useless in normal hours DO NOT SIGN UP

I have spent four months trying to get out of a one year MIFI contract (that finished in July) for a device I lost in the spring. I have spent hours and hours, just to be fobbed off. Just awful service. AVOID!!!!!

Abingdon Three Mobile  
I know a lot of people are down on 3, but it really has felt like they were putting in some serious infrastructure round here. I'm in an 'outside' reception area, on the fringe of coverage, so I got an external aerial for my 5G hub. It was pretty good at the beginning (4 months ago), averaging 200Mbps, but it broke every couple of weeks. Now things are better: seems steady, and am routinely getting 500Mbps at my computer. That's 4 times faster than most fibre. And it doesn't go slower in the evenings. Am quite impressed: for 29 quid a month it's impressive. I hope it stays like this! Well done three...

hackney Three Mobile  
These guys have been quietly taking money from my account for a service which they cannot actually provide. I had this router from when it was Relish. I thought that it was cancelled but I was wrong. Now when I tried to reconnect last week I was eventually told that there was no 4G available in my area. Then they tried to sign me up to 5G and wanted my card details etc. I checked on their site and found that there is no 4G or 5G mast in my location and would I like to be contacted when it eventually comes around! I have cancelled the direct debit myself and immediately go an email saying that I had not replied to previous emails about the Direct Debit cancellation?? These guys are liars and thieves.They even have the front to complain when you stop them from stealing your money!!!!

Waste of money at best we are running 1.77 mbps download speed. Rang to complain after 1 month of start of contract when the cancellation period was over as that's when it went garbage. Been calling at least once a month so for nearly 18 month and they only have records for last 4 month said I have never complained before. Then to be told the coverage in my area is very poor but in the shop when we took the contract out they stated it runs near on perfect. Absolute ******** will not renew, robbing tears.

Doncatser Three Mobile  
Worked fine in the beginning (first month - February 2020) after which they started upgrading the network, this meaning 2 days a week the network would be down completely and when was working I had 2-3 mb speed. November 2020 network is up and running properly upgraded to 5G with speeds than can reach sometimes 5 mb. 2 more months and I will close all 3 contracts with 3.

Southampton Three Mobile  
Oh dear, I have the same tale of woe that everyone else is posting. When I first switched to three mobile broadband last year it was good enough - getting ~7mbps. But now the service has dropped to the point that web pages won’t load and the servers can’t be contacted. Right now I have 0.4 mbps. A lot of the day it is totally non-functioning. But I have full signal strength. So clearly it is a throttling issue that 3 are doing. They have oversold their capacity until no one gets any. I have tried complaining but it is a futile waste of many hours and nothing is resolved. Why is it so difficult to complain to them? - and why don’t they take the complaints seriously? I have many neighbours who are in the same situation – all wishing they were not with 3 – so it is not just my equipment. Earlier this year I complained and they reset something on the network, and suddenly service was resumed. (removed the throttling?). But it had all dwindled to nothing. Full signal strength and no delivery sums them up. And they don't want to know.
