EU negotiators agreed on the following wholesale caps:
3.2 cents per minute of voice call, as of 15 June 2017
1 cent per SMS, as of 15 June 2017
A step by step reduction over 5 years for data caps decreasing from €7.7 per GB (as of 15 June 2017) to €6 per GB (as of 1 January 2018), €4.5 per GB (as of 1 January 2019), €3.5 per GB (as of 1 January 2020), €3 per GB (as of 1 January 2021) and €2.5 per GB (as of 1 January 2022).
