The number of public payphones in Ireland continues to drop with just 456 left, compared to almost 4,000 a decade ago.
Payphone usage has declined dramatically in recent years because of the popularity of smartphones.
In 2008, there were more than 3,500 payphones in the Ireland with the decline starting when Eircom put almost 2,000 payphones out of service.
In the past few years, more phone boxes have been removed around the country with more than a dozen being removed in the past six months (468) in July 2019 compared to 456 now.
An Eir spokesman said 21 payphones have been removed so far this year with requests from council and continued anti-social behaviour cited as the most common reason for removal.
There were on average 235 calls per day in September 2019 equating to on average 0.05 call from each payphone daily.
Eir said if a payphone is used for less than one minute a day on average and if emergency services calls do not count for more than 30 seconds of each minute, it can remove it.
The company is set to replace old payphones around Dublin with upgraded versions that will include Wi-Fi, interactive touchscreens and information services for tourists.
Eir applied for planning permission earlier this year to upgrade the kiosks in more than 20 locations around the city.
In a statement, Eir said it has agreed a programme with Dublin City Council to improve public payphones at selected locations in Dublin, subject to planning approval.
"The proposed structures are open stand-alone kiosks designed to reduce instances of anti-social behaviour, improve street furniture and provide enhanced services to users including interactive, digital information points."
