What Is an eSIM and Why It's Perfect for Caribbean Drivers
An eSIM (embedded SIM) is a digital SIM card built into your phone that connects you to local networks without physical SIM swapping. For Caribbean road trips, this means:
- Instant activation – Get connected before leaving the airport to navigate to your rental car
- Reliable navigation – Real-time GPS and traffic updates while driving unfamiliar roads
- Safety first – Emergency calling and roadside assistance access anywhere
- Cost control – Pay 70-90% less than international roaming charges
- Multi-island flexibility – One solution whether you're exploring just Jamaica or island hopping to Barbados and beyond
Unlike fumbling with tiny SIM cards at airport kiosks, your Caribbean eSIM activates with a simple QR code scan, keeping your home number active for banking OTPs and WhatsApp messages.
