No! This is the #1 roaming trap. Although Gibraltar is geographically in Europe, it is NOT a member of the European Union (EU). Your "Roam Like at Home" (RLAH) plan (e.g., from Spain, France, Germany) does not apply. The moment you walk across the border from La Línea, your phone will connect to a non-EU network, and your carrier will charge you extremely high "Rest of World" rates. A Cellesim eSIM is the only way to get a fixed, cheap data price.
Planning the trip? See our Gibraltar eSIM plans, install in one tap before you fly, and land online. Free VPN included.
