Absolutely terrible customer service. They charged me for 2 further months after I called them to say I moved, yet left me no messages. I was a loyal customer for years and now they charged me for months I didn’t use. The broadband was slow and definitely unreliable. I will never be using their services again

Three mobile broadband service is horrible. Web page takes indefinitely to load. I tried paying my daughter school fee on line this evening, it did not get through because of "frustrating slow speed". I regret that I bought it service.

Download speeds are incredibly unpredictable; very occasionally you might get 20mbps, but you usuallyget 0.5-2mpbs. Customer Service will have you move the router around, change Wifi frequency etc., but it does nothing to help the really poor consistency of their services.

What I really don't understand is my mobile provider Smarty use the Three network, and my phone gets far greater download speeds than the router sat in the window. I hotspot more than I use the Router now, which begs the question why bother paying for the service in the first place.

Easy to choose them Relish/Three in the first place due to their quick delivery/set up times, but in the end really not worth the hassle.

I thought this would solve my BB problems as i live in the countryside.
The signal drops & rises,surely i should be able to get a reliable 20meg d/load speed.Some times it drops to around 3-4 meg d/load.I need to shop around once my contract is up.

Bolton Three Mobile  
Lovely little cube for 4g internet. However, crap is all I can say. Best I've ever had was 10mb, usually it's not above 3mb. I live in a flat, however it sits on the window sill and if go further in to my flat, I can get 38mb on my mobile which is on Tesco mobile (using O2 network). When I bought it, 5g was rolling out the followimg week, that was in July and 6 months later, I'm still getting 1mb of 4g.
Cannot wait until my contract finishes. P.s. this was written on my mobile data as the wifi waste slow

Eastbourne Three Mobile  
These guy's are useless, customer service is ok if u speak Indian/Pakistani. But i am English and have yet to speak to an English employee of 3. Everything is lag lag lag with it no matter where is put it. I wish i never got this cube, yes alexa is ok thats it. Avoid it folks its useless for anything apart from browsing the web, streaming is a nono same as online gaming

Belfast Three Mobile  
Very unreliable and if you plan on using this for online gaming it will perform poorly if anybody else is connected. 2 or 3 streaming devices is enough to faulter three and their broadband.

Gloucester Three Mobile  
Have had broadband supply from 3 for 2 months, during that time we have lost signal numerous times, for up to 5 days. Customer service is appalling, do not seem to care, say someone will contact within 2 days, and will try and get signal back within 7. Have never had any problems with previous suppliers. Only have 1 stars because you cannot give none.
