, will see how it ends. I've been there in that house with my airBalticcard and a N5000 and a N8310, there is definitely no signal. 20m outside you get a weak signal from i.e. Vodafone.
I was also thinking about another mobile and an external antenna to plug in, but I don't have any experience with this. Which mobile? Which antenna? That's the reason why I wanted to go for callback......
