Connectivity costs in Bulgaria depend on your home country. As Bulgaria is an EU member, EU citizens generally benefit from 'Roam Like at Home' policies. However, for UK travelers post-Brexit, most UK carriers like O2, Vodafone, and Three have reintroduced daily roaming charges, typically £2-£6. For US travelers with carriers like AT&T or Verizon, expensive daily international passes (often $10-$15) are usually the only option. WorldESIM offers a predictable and affordable alternative.
