Uruguay is not included in typical US, UK, or EU domestic roaming agreements. Therefore, using your home SIM card from carriers like AT&T, Verizon, T-Mobile (US), or Vodafone, O2, EE (UK/EU) in Uruguay will almost certainly activate their highest-tier international roaming rates, often structured as expensive 'Day Passes' (e.g., $10-$15 per day) or per-MB charges. For heavy data users, DataESIM offers a significantly more cost-effective and transparent solution, providing high-speed local data without incurring exorbitant roaming fees.
