The roaming status in Romania for UK or US SIM cards is conditional. Romania is an EU member state, which means 'Roam Like at Home' applies to EU citizens. However, for non-EU SIMs:
- For UK SIM cards (post-Brexit): Many UK operators, including O2, Vodafone, and Three, have reinstated daily roaming charges for EU usage.
- For US SIM cards: US carriers typically classify Romania as an international roaming zone, incurring significant per-MB or daily package fees. DataESIM offers transparent, high-volume data plans for Romania, circumventing these unpredictable costs.
