Ecuador uses the US Dollar; does this mean my US (AT&T/T-Mobile) mobile plan will work without extra charges?

It's a common misconception that because Ecuador uses the US Dollar, US mobile plans will automatically work without international roaming charges. This is incorrect. Ecuador is an independent country, and your US domestic plan from carriers like AT&T, Verizon, or T-Mobile will treat it as an international destination. You will likely incur expensive international roaming fees, often in the form of daily passes (e.g., $10-$14 per day), which can quickly add up. WorldESIM provides a cost-effective and transparent alternative for staying connected in Ecuador, avoiding these unexpected charges.
