Mobile phone customers in Northern Ireland are counting the cost of living along the border of the country as roaming charges regularly affect them.
Regulator Ofcom said that people in east and north County Londonderry in particular, as well as Partstewart and south Armagh are worst affected by this.
Around 30 per cent of those surveyed in south Armagh stated the problem occurs almost every day.
Ofcom estimates that it costs customers along the border an extra £300 a year because of making calls and using data without realising the signal is being provided by a different company.
New regulations from the EU to prevent so-called bill shock when using mobile phones in Europe came into force earlier this month and the Commission voted the plans in earlier this year.
"The latest European Roaming Regulation places responsibility on mobile operators to take 'reasonable steps' to protect their customers for inadvertent roaming charges," Ofcom's Northern Ireland director Jonathan Rose commented.
