A second mobile phone company has admitted that it overcharged its customers.
Vodafone Ireland charged more than 20,000 customers too much for roaming costs over the past month.
The admission comes just days after O2 said it overcharged 70,000 customers for calls while abroad.
Speaking on RTÉ Radio, a spokeswoman for Vodafone said that the overcharging amounted to €147,000, and that the accounts of those affected had since been credited with the amount of the overcharge.
