For EU citizens, 'Roam Like at Home' generally applies in Bulgaria. However, if you are from the UK (post-Brexit), most UK carriers like O2, Vodafone, or Three have reintroduced daily roaming charges, typically £2-£6 per day. For US travelers, carriers like AT&T or T-Mobile will charge international 'Day Pass' rates, usually $10-$14 per day. Truly Roaming offers a transparent and cost-effective solution for your monthly stay.
