That's impressive .

You should be selling your services! 😃

Thanks for your very interesting and helpful reply.

As you say, we're in a very similar situation, and from the roof of my house there's a line of sight to the 4G mast. I've had a signal of 30Mbit at the top of my roof on a ladder (and if I can convince my wife to cut back a largish holly I think it will be better)

My cottage is mainly 20 inch stone walls, so wifi doesn't work very well, and so I'm looking at an aerial on the roof connected to a router indoors then connected by a switch / ethernet cables around the hose (installed when we renovated), although I'll test whether wifi will work from the roof level by going up the ladder, using my phone as a hotspot and tethering to laptops etc.

The smarty sim looks good and as it's effectively just a one month commitment I'll order one. The one I've seen is £20 for unlimited data, and I assume that's the same as yours.

One minor question, what is the issue over " ..put up with CGNAT and Web proxy.."

Multiplayer gaming often hits problems with multiple levels of NAT (Network Address Translation) which is what your home router does. CGNAT is where this is ALSO happening in the network due to the lack of IPv4 addresses, so you get two levels of NAT.

Some networks also force all web connections through a proxy to reduce their costs, and this can interrupt some web based systems. It is generally only done by the lower price internet providers.

You should check which networks are on the mast, if you have Three, you might also have EE, as often they are co-located. The transmitter panels will be at different heights on the mast, so you might get a better EE service, avoiding the trees, but for more money!

Thanks for that. Smarty use Three, but I assume from what you're saying they may use EE as a proxy.

I've checked the internet speed with speedtest on my mobile for Three, EE and vodaphone using different sims, and the speeds are all same, so hopefully won't have a problem.

Out of interest, do you know how you can find out the location of local masts. Apparently Mastdata used to have that information but not any longer.

Nope, the two networks are separate, just if you needed to go to the attic for a signal from Three, you might get a signal in a room further down the house from EE.

If you want to avoid the web proxy, or CGNAT then you can get a SIM from Three.

The same? Depends on your phone, but it is likely you will get different speeds on different networks as they all have different allocations of frequencies. Also they will have different number of users in each area.

Mastdata has ancient info.

The O2 website shows their masts, which is often useful as they frequently share with Vodafone.

The cellmapper website (https://www.cellmapper.net/) is a crowd sourced, volunteer, site that might show your masts. If you have an Android phone if you install the app, you can drive around the location and upload your data and it will update the map.
