Is siteviewer accurate? If it says a mast has 4g is it a certainty it has it?
I am testing out Vodafone at the moment since Three has gone to the dogs since lockdown and was expecting after moving my aerial to point at the mast less than 500m from me that i would be getting 4G and some decent speeds. I was previously getting 4G with Three but the mast is very far way so the speeds at times were terrible. I have only been getting 3g since i started testing last week with vodafone even though Siteviewer says there is 4g there.

When I disconnect my router from the aerial I get connected to another mast which doesn't make sense considering the next closet is far further away.
I can only assume that Siteviewer is wrong and the mast does not have 4g vodafone since the max i can get is 3G
