Mobile wifi instead of landline broadband question.

I can't see the plans as Three won't accept my postcode, but they offer a 30day rolling plan.

Why do they need a postcode for "mobile" broadband?

Just put in another nearby one!

They need to check if the network too congested
They no such requirement for three mifi, but if you want to sign up their home broadband, postcode is required.

Tried that and didn't work.

Despite the fact that a year ago we had the 4G home broadband from Three for a month and it worked excellantly.

what is the 4g signal like indoors, mine is barely usable at 2.5Mbps and outside it goes to 18-19. If you get good reliable speeds then I would use a router from someone like asus which can take a sim.

Why not get an outside aerial to feed the stronger signal to indoors, if necessary?

Because you might not be allowed to attach stuff to the outside of your dwelling or drill holes to feed cables

Because it's complicated https://www.ispreview.co.uk/index.php/2020/04/how-to-choose-an-external-4g-or-5g-mobile-broadband-antenna.html

Because it costs hundreds of pounds


EDIT : or the actual reason below 

They don't have to cost hundreds. Depends from where you buy it. I don't know if there are any rules against it. A suitable system can cost under £50, dependent on where you buy it and the frequencies needing coverage.
It's not that complicated. Quite a few competent people on this forum; don't underestimate their intelligence. You can use your Smartphone to determine which bands need to be covered and in which direction you should place the antenna.

Of course the router does matter, as does the network you choose. 

Let's take EE as an example: 

Firstly you need to make sure that your modem/router covers the relevant frequencies. In the case of EE: 
B1 (2100 MHz) B3 (1800 MHz) B7 (2600 MHz) B20 (800 MHz)

You can also discover which of those frequencies are available to you at your location using your current Smartphone(which incidentally, may support CA. More on that coming up).

Once you have determined that, the next thing to look at is Carrier Aggregation(CA). The router in the OP is not capable of CA and so will have a limited speed capability, of perhaps less than 20 Mbps.
If you want higher speeds, you'll need CA capability. In other words, your modem router having the ability to combine the bands.

In the case of EE, their combinations look like this:  
CA_3C (B3+B3)
CA_3A-7A (B3+B7)
CA_3A-7C (B3+B7+B7)
CA_1A-3C-7C (B1+B3+B3+B7+B7)

Your router will need to have the ability to match one or more of these combinations to obtain higher speeds. 

Your Smartphone can be a useful tool in determining what is needed.

Many thanks that is really useful, I want to use a provider that has a rolling 1 month/30 day unlimited data contract, am i correct in thinking that only ID and Lebara offer this?

Three(UK)'s rolling monthly offer costs £26. 

4G Bands: B1 (2100 MHz), B3 (1800 MHz), B20 (800 MHz), B32 (1500 MHz Suppl. DL)

Carrier Aggregation CA_1A-3A (B1+B3)
