Since Ecuador uses the US Dollar, does my US (AT&T/T-Mobile) plan work for free?

This is a really common misconception, but unfortunately, no! While Ecuador uses the US Dollar as its official currency, it remains an independent country and is not part of any domestic US mobile plan's free roaming zone. Your home carrier, whether it's AT&T, T-Mobile, or Verizon, will almost certainly charge you expensive international roaming rates, often through daily 'Day Pass' fees that can quickly add up. SouthESIM offers a much more budget-friendly and transparent way to stay connected in Ecuador, avoiding those surprise charges.
