The UK government is considering introducing a "national roaming" scheme to the UK, in order to improve rural mobile coverage.
If given the go-ahead, it would allow consumers to switch between networks when they run out of signal - similar to how international roaming works.
According to a spokesperson for the Department of Culture, Media and Sport, the government is already spending £150 million to improve rural coverage, and is looking at fresh options.
"The government has made clear it wants to ensure the UK has world-class mobile phone coverage as part of our investment in infrastructure for the long-term economic plan," the spokesperson said. "We are investing up to £150m to improve mobile coverage in areas where there is currently no coverage from any of the Mobile Network Operators.
"Of course we want to look at what more can be done in areas with poor coverage."
However, mobile operators aren't so keen on the idea, arguing that national roaming – which involves sharing services with rivals – would cut out any incentive for improving coverage through better infrastructure and bigger investments.
They also reckon that the costs involved would hike up consumers' bills.
However, it is believed that the government could actually use existing legislation to push through the move.
Three seems more open to the proposed scheme, saying, "We've invested heavily to bring coverage to around 98 per cent of the population.
"We support the principle of expanding coverage to address areas less well served and are in discussions with government about the most effective means to deliver that."
