I do take issue with your last statement.
I don't think that is a fair assessment to make about an entire product, as it is entirely based on your own experience. A better way to put it is that it didn't work for you.
In my experience, in an area where Fixed-Line Broadband only provides horribly slow ADSL speeds and reliability, EE's 4G Mobile Broadband gets us speeds of up to 100 Mbps and it happily allows us to stream on multiple devices.
Using the same logic I could say it's the best thing to ever exist, but I won't say that because it is massively dependent on; the use case, the size of property, and the quality of the mobile network connection in the area. It's all subjective.
A Wi-Fi coverage issue within the property can be resolved through the use of range extenders, but in my case most devices are focused around the location of the Mobile Router so I haven't needed to explore that. This sounds like it may have been the issue in your case however.
If you had a suitable Fixed-Line Broadband solution available to you, then of course that would be a better option and this seems to have been reflected by the comments of the EE Guide and the subsequent solution, but not everyone has that same luxury and often do have to rely on a mobile broadband option.
In future please state your opinion as what it is, an opinion. It is not representative of everyone's experiences.
