When should I install my eSIM?
We recommend installing your eSIM before you travel while connected to Wi-Fi. Data usage usually starts once the eSIM connects to a supported network at your destination.
Will my eSIM work as soon as I land?

What if I run out of data?
You can top up your eSIM at any time while it's active. Log into your account, purchase a top-up, and continue using data without reinstalling the eSIM.
What does an Unlimited Data Plan per day mean?
Unlimited daily plans include a fixed amount of high-speed data each day. Once that daily limit is reached, your speed is reduced rather than cut off. High-speed access resets the following day.
What happens after the high-speed limit is reached?
After the daily high-speed allowance is used, speeds typically drop to around 1 Mbps or lower. This is enough for messaging apps, emails, navigation, and basic browsing.
