Which Bulgaria carriers we run

Bulgaria Claude (Anthropic) activations come from a mix of tier-1 mobile networks and the MVNOs that diaspora communities lean on for cheap international rates. The pool rotates with stock — right now you're likely to get a SIM from A1 Bulgaria, Yettel Bulgaria or one of the MVNO brands that ride those same networks: Vivacom. All real mobile-network SIMs, not VoIP. Claude (Anthropic)'s anti-VoIP detection (the same check that rejects Google Voice and Twilio numbers) sees these as regular Bulgaria mobile lines because that's what they are.
