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
- Log in to esima.com.
- My account → My eSIMs.
- Find the eSIM you want to top up. Tap "Top up data".
- 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."
- Pick the same kind of plan you already had (or a different size if you want).
- Checkout normally. We charge your saved card or accept fresh payment.
- 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.
