Will my existing US, UK, or EU SIM card provide free roaming in Grenada?

This is a common misconception, and it's vital for budget travelers to know: No, free roaming is highly unlikely! Grenada is an independent nation, meaning it's not part of any domestic roaming agreements your home carrier (like AT&T, Verizon, T-Mobile, or UK networks like Vodafone) might have within the US, UK, or EU. Using your regular SIM card there will almost certainly incur expensive international roaming charges, which can quickly add up. A SouthESIM is a much more budget-friendly way to stay connected on the Spice Isle!
