Call the World from your O2 Mobile for only 3.5 cent per minute.

1Call allows Irish mobile customers to make cheap international calls directly from their O2 mobile.

1Call is a separate add-on service which works with your existing mobile tariff by providing cheap international calls at much lower rates than your current mobile provider.

Since it works as a separate service from your existing network plan it means that there are no phone numbers to change, no contracts to sign and no commitments of any kind.
