No! This is the #1 roaming trap. Although Armenia is in Europe, it is NOT a member of the European Union (EU). Your "Roam Like at Home" (RLAH) plan does not apply. Most EU, UK, and US carriers (like AT&T, Vodafone, O2, T-Mobile) will charge you extremely high "Rest of World" international roaming rates (e.g., $10-$15 or £6 per day). A Ti Porto in Viaggio eSIM is the only way to get a fixed, cheap data price.
