How to top up an eSIM you've already installed

Top-ups extend an existing eSIM with more data and (optionally) more days. You keep the same phone number, the same profile on your device — only the data quota and validity period change.

Step-by-step

1. Log in to esima.com.
2. My account → My eSIMs.
3. Find the eSIM you want to top up. Tap "Top up data".
4. You land on the country hub with a green banner: "Topping up your existing eSIM — pick a plan and the data is added to the same eSIM."
5. Pick the same kind of plan you already had (or a different size if you want).
6. Checkout normally. We charge your saved card or accept fresh payment.
7. Within 60 seconds, the data lands on your existing eSIM. No reinstall, no QR, no setup. You just have more quota.

A few rules

• You can only top up an eSIM that's still active (status: provisioned). Once an eSIM is expired or cancelled, you need a fresh one.
• Top-ups use the same operator/network as the original. You can't switch networks via a top-up.
• A top-up resets the validity counter for the new plan size. If you bought 7-day and top up with another 7-day mid-trip, you have 7 more days from the moment the top-up activates.

Why not just buy a new eSIM?

You can — totally fine. But it means another install, another phone-number swap, another QR. For trips lasting longer than your original plan, top-up is faster.
