For Brazil, check out Airalo, Nomad, or Holafly all solid eSIM options with big data packs (Nomad has a 20GB plan for LATAM). They work across devices, and you can hotspot without issues. Airalo is usually the cheapest, but Holafly offers unlimited data if you’re cool with a higher price. Just make sure your tablet supports eSIMs too. I’d grab one before you land — way less stress.
