We recommend installing your Truly Roaming eSIM before you depart. The plan's validity period only commences when your device first connects to a network in a covered country. This means you can complete the setup process at home, ensuring immediate data access for critical tasks like booking transport or checking maps as soon as you land in Rio de Janeiro or arrive in Kingston. Be ready to work from day one.
