Then why does it only ever do it on voda and not sims from other networks. Other networks, what it states is generally what you get. With a voda sim it always massively over estimated.
The signal in terms of actual reception quality is as indicated I think what your referring to is what I'm experiencing where it will say you've got full bars but the actual service quality isn't that great - with intermittent data issues, varied voice quality, etc.
