Three has more than doubled the size of its mobile network in Northern Ireland following a £12 million investment, and has also helped customers avoid roaming charges along the border with the Republic of Ireland.
In addition, the mobile operator says it has rolled out advanced 3G technology known as DC-HSDPA, which helps give users faster internet browsing and data download speeds.
The network upgrade, which started last year, means Three can now claim a Northern Ireland network population reach of 95 percent - up from just 76 percent previously.
The operator has more than doubled the number of it mobile transmission sites in Northern Ireland to well over 400 to achieve the service improvements.
Three chief executive Dave Dyson said: “Mobile users in Northern Ireland have not always benefited from the kind of investment seen elsewhere in the UK. We wanted to address that so we’ve massively increased our coverage and performance to ensure all our customers in Northern Ireland can enjoy a great mobile internet experience.”
Three has also introduced an answer to the perennial problem of the costs associated with cross-border roaming for customers in Northern Ireland’s border counties.
Three’s new service Feel at Home means that if customers roam on Irish Republic networks their usage will form part of their normal domestic allowance, and any calls or texts to other UK numbers won’t cost them extra.
Northern Ireland enterprise minister Arlene Foster said:“I hope Three will continue to see Northern Ireland as an investment opportunity as new technologies and services emerge.
"I also welcome the fact that Three has introduced a solution to the problem of inadvertent roaming, which affects many people in Northern Ireland.”
Three says it has 175,000 customers in Northern Ireland, with six percent of them living in border counties.
