Truely

Truely's patented Switchless technology is the standout feature, one eSIM stays active across 190+ countries without manually switching providers at each border crossing. This matters in the Caribbean where you might island-hop between Puerto Rico, the US Virgin Islands, and independent nations, since traditional eSIMs require plan changes. Their unlimited plans include 5GB per day at full 4G/LTE speed before throttling.

The Switchless approach eliminates the friction of re-scanning QR codes, managing multiple eSIM profiles, or remembering to activate a new plan upon arrival. If you're doing a Caribbean multi-island tour and value simplicity over cost optimization, Truely's single-eSIM-for-everything model beats switching providers at each stop.
