It's a common misconception, but Grenada is an independent nation and is not part of any domestic roaming agreements with US, UK, or EU carriers. Relying on your home SIM for data in Grenada will almost certainly incur exorbitant international roaming charges, which can quickly add up. HotelESIM offers a much more economical and predictable solution. By using HotelESIM, you can enjoy seamless connectivity without worrying about unexpected bills, allowing you to fully relax and enjoy your 'Spice Isle' vacation.
