Frequently Asked Questions
Yes, Truely offers eSIMs that can be used with compatible devices in the country. You can enjoy fast internet nationwide without needing a physical SIM card.
We recommend buying a Truely eSIM early if possible. While you can purchase an eSIM anytime and anywhere, it's advisable to get one earlier to avoid scrambling for an internet connection when you arrive at your destination.
Don't worry—your data plan will not activate the moment you buy it. For instance, if you purchased a 30-day data plan today, the 30-day countdown will not begin until you connect to a mobile network in your destination. In other words, your plan will activate only when you've arrived. For a completely seamless experience, buy and install an eSIM a few days to a week before your departure. This will let you connect to the internet as soon as your plane lands.
