Bury St Edmunds MP David Ruffley is urging people to join in a Countryside Alliance campaign to map true rural mobile phone reception.
The Alliance wants people to download the free RootMetrics app from the iTunes app store or Google Play. It records signal strength data anywhere which will be used to push Government and providers for better reception.
Mr Ruffley said: “Everybody pays the same rates for their phone packages, but they don’t all receive the same level of reception. That means some people in Suffolk aren’t getting a good deal.
“I want the Government and providers to realise this.”
