Editorial policy
77 articles have gone live since launch, at a pace of about 25.7 per month currently — deliberately moderate, to leave time to check each piece. This editorial line has existed since June 16, 2026.
No article is published without a byline: the author's background is detailed on a dedicated page.
Marina Costa — Background: Marina is a travel writer who has crossed Brazil from Rio to the Amazon. At Brazil eSIM she compares Claro, Vivo and TIM data plans and helps visitors stay online without roaming fees.
This site focuses on eSIM data plans and carrier options for travelers, anchored on Brazil but branching out to the practical, carrier-specific questions people actually search before a trip: comparing eSIM options like Airtel for Brazil, checking whether T-Mobile or AT&T prepaid plans work there, unlocking a T-Mobile SIM for use elsewhere, or finding eSIM options for other destinations such as the USA or Singapore. It doesn’t cover general travel planning — itineraries, sights, where to stay — since the focus stays on connectivity and carrier logistics rather than trip planning. Topics are chosen from the concrete carrier and coverage questions travelers face, not from broader tourism content.
We keep this boundary on purpose. Covering ten subjects without mastering any of them holds no interest for us; we would rather master one.
Some of our articles link to partner sites. That status changes neither the content nor the opinion expressed: we do not favor an option for being a partner, nor exclude another for not being one.
We consider an outdated article worse than no article at all, so each piece is revised whenever a relevant change happens, or removed if it can no longer be trusted.
