Can we expect free roaming in Panama with our US SIM cards, like AT&T or T-Mobile?

Hold on a second, that's a common misconception! While Panama uses the US Dollar, it's a completely independent nation, meaning your US domestic plan doesn't magically extend there. Most US carriers, such as AT&T, Verizon, or T-Mobile, will hit you with hefty international "Day Pass" charges, often $10-$14 per person, per day. For a group trip, those costs add up fast! Triply offers a much more budget-friendly and predictable way for everyone to stay connected without those surprise bills.
