One of our regular readers has input a Nairn post code into a BBC survey page and this is the result. The BBC page does give a few caveats however:
"Each box on the map indicates the average reception within that area over the survey period. Areas showing no coverage could be the result of a single phone losing signal. The map does not take into account factors such as reduced reception while in buildings. The map is not intended to replace the service providers' own coverage maps when making a decision about taking out a mobile phone contract."
It would be interesting to know if this is actually the case for Nairn and how many people took part locally, the boxes along the A96 suggest that people passing through Nairn who were participating with the BBC application have had an influence on the results. So how smart is your smartphone at times in and around Gurnshire? Here's the relevant BBC page if you want more information on their survey.
