EU roaming data limits and wholesale caps through 2027

The wholesale cap is a price per gigabyte

The regulation schedules the maximum wholesale price paid between networks. It also helps cap permitted consumer surcharges after an applicable fair-use allowance, with VAT where applicable. The January 2027 step lowers the cap from €1.10 to €1.00 per GB. Source 1 Source 2

An open bundle uses twice the plan price divided by the cap

For a qualifying open bundle costing €15 excluding VAT, the example yields at least 27.27 GB in 2026 where a fair-use limit is applied. The same price gives 30 GB under the January 2027 cap. The operator has to communicate the allowance. Source 2 Source 3 Source 1

Prepaid credit uses the remaining amount at the start of roaming

For an eligible prepaid per-unit plan, the minimum is the remaining credit excluding VAT divided by the cap when data roaming begins. €15 of remaining credit yields about 13.64 GB in the 2026 example and 15 GB at the 2027 cap. Source 2 Source 1

Check the destination and network

The European Commission says the regime covers travel in participating countries and was extended to Ukraine and Moldova on 1 January 2026. A satellite connection on a flight or ship can be outside the regulated roaming network, with a separate charge. Source 3 Source 2
