What happens if I use up all my data for the month?

On the 10 GB plan you can add another 10 GB at any time. You buy it in the Ohayu app, without changing your eSIM, and it's there for the rest of your billing month. The Unlimited Global plan doesn't need a top-up. You get full speed for the first 30 GB each month, then you stay connected at 1 Mbps until your next month starts. See how to top up your eSIM.

Global plans can't be switched to a different size. If you'd rather have the other Global plan, cancel this one and buy it. You'll always have an easy way to stay connected.
