It's a common misconception, but relying on your home carrier's SIM for roaming in Grenada can lead to a nasty bill shock. Grenada is an independent nation, not part of any domestic roaming zones for US, UK, or EU plans. Your AT&T, Verizon, T-Mobile, or Vodafone UK SIM will incur exorbitant international roaming charges, often $10-$15 per MB or minute. eSIMFlyer offers a prepaid, budget-friendly alternative, giving you peace of mind and predictable costs while exploring the 'Spice Isle' without any hidden fees.
