eSIM — Grenada
Network coverage in Grenada
Grenada has two mobile operators: Digicel (market leader, fastest 4G speeds and broadest coverage) and Flow. Both provide nationwide 4G/LTE across most of the populated territory. For St. George's, Grand Anse Beach, Gouyave or Grenville, both operators deliver reliable 4G. 5G has not launched in Grenada.
Digicel leads on 4G data speeds and coverage. Flow carries a stronger 3G signal in areas where lower frequencies reach further — relevant on Carriacou and Petite Martinique where coverage is more limited. Among the providers on this page, Airalo routes via Digicel. Saily, aloSIM and Yesim do not publicly disclose their Grenadian carrier. For specific dead zones on Carriacou, Petite Martinique and the northern coast, see the field tip above.

VPN, passwords and documents
On hotel or café Wi-Fi, a VPN can be useful to keep your browsing private from the network operator. A password manager is also worth having for managing account access on the road. A secure cloud backup of your passport, visa and accommodation details can also be useful — keep an offline copy too. None of these are mandatory.
