Vodafone is to bring 3G connectivity to another 40 mobile broadband 'not-spots' in remote parts of the UK.
The rural communities will benefit from the mobile operator's Rural Open Sure Signal programme, which is designed to increase coverage across Britain.
Many of the locations are in Wales and Scotland, with five Shetlands villages - Aith, Baltasound, Fetlar, Sandness, and Skeld Sandsting - among those set to benefit.
The installation of Vodafone’s Sure Signal technology will allow local people and businesses to take advantage of 3G services for the first time.
Jeroen Hoencamp, Chief Executive at Vodafone UK, said he is "excited" about the transformation the "pioneering" Rural Open Sure Signal programme will deliver to rural parts of the country.
"The communities who have worked with us to introduce Open Sure Signal have all told us how life has improved markedly, from the ability to make an appointment at the local doctor to telling their families they are running late for lunch," he explained.
"We are committed to investing hugely in our network and using innovative technologies such as Sure Signal to provide coverage to rural communities means we can reach areas where it’s been impossible to reach using traditional means.”
The Rural Open Sure Signal scheme was launched in July 2014 and has already seen 13 locations connected to Vodafone's 3G mobile network.
