Ireland’s eir is to zero-rate data for consumers using Facebook, Twitter and Instagram.
The offer is applicable to Meteor prepay and bill pay customers as well as eir Mobile postpay customers on 4G plans costing €20 or more.
Subscribers have a fair usage limit of 60GB a month, after which eir reserves the right to limit the offer, which it said was indefinite in length.
Tethering is allowed, but roaming is not.
The campaign, entitled #lovedata, will be supported by TV, radio, outdoor and digital activity.
eir has 1.1 million mobile customers and recorded flat year-on-year sales of €87 million in the first three months of the year.
Maeve O’Malley, Director eir Mobile & Meteor, said: “We know people love data so we’re giving them more, for free, which will be applied across the three most popular social sites; Facebook, Twitter and Instagram.
“Simply put, customers will receive unlimited usage of Facebook, Twitter and Instagram without eating in to any of their data allowance.”
eir is busily integrating Setanta Sports Channel Ireland into its TV offering, having acquired the sports broadcaster last December.
Earlier this month, the operator revealed it is set to get backing from Singapore’s sovereign wealth fund.
GIC announced plans to purchase up to €230 million of eir’s shares.
