Traveling means discovering, exploring, and sharing. But running out of mobile data can quickly turn a pleasant experience into a source of stress. Thanks to eSIMs, recharging your data has become simpler than ever. How can you monitor your usage, recharge your eSIM, and optimize its use to stay connected with peace of mind during your travels? We’ll give you the answer!
How to monitor your eSIM data?
Proactive data management is an excellent way to avoid unpleasant surprises. With an eSIM, monitoring your consumption is quick and easy thanks to widgets and notifications on your devices. Here’s how to do it:
Monitor your data on iPhone
- Press and hold your finger on the home screen to enter Edit Home Screen mode.
- Tap the « + » icon in the top left corner of the screen to add a widget.
- Scroll through the options and select your eSIM’s dedicated app, such as the Vostra app.
- Choose a widget from the available options (small, medium, or large), then tap Add Widget.
- Long-press the widget again to configure it to your preferences.
Configure notifications for iPhone
Receive automatic alerts when your data reaches a critical threshold:
- Go to Settings on your iPhone.
- Navigate to Notifications, then select the Vostra app.
- Choose a suitable alert style (for example, banners or sounds).
- Enable the Show Alerts option.
Configure notifications for Android
Android users can also receive notifications by following these steps:
- Open Settings, then go to Notifications.
- Navigate to App settings.
- Select the Vostra app and enable notifications.
How does an eSIM recharge work?

Imagine you’re traveling to London and using an eSIM with a 3 GB plan valid for one week. After using your data to browse social media, look for places to visit, and share memories, you notice your usage reaches 90% of your plan. Don’t panic! A recharge is enough to extend your connectivity.
Here’s how it works:
- Open your eSIM management app (Vostra).
- Access your active plan to check your usage.
- Purchase a top-up plan in a few clicks.
In a few seconds, you’re connected again, ready to continue your adventures.
What if your eSIM doesn’t have a top-up option?
Some eSIM plans do not allow direct top-ups. If this happens, here are two solutions:
- Download a new eSIM: With Vostra, you can quickly buy and activate a new eSIM to continue your trip without interruption.
- Plan for more data: Before you leave, evaluate your data needs to avoid surprises.
But how does an eSIM plan work?
Unlike traditional SIM cards, eSIMs are completely digital. Once activated, an eSIM allows you to connect to a mobile network in minutes, without having to insert a physical card.
This way, you get fast and convenient mobile connectivity, wherever you are in the world.
eSIM plans vary based on several criteria:
- The volume of data included.
- The validity period (for example, 7 days or 30 days).
- The geographical coverage (local, regional, or global).
With an eSIM, you’ll no longer have to pay high roaming fees or look for a local SIM card upon arrival. Everything is done online, before or during your trip.
How to recharge your eSIM
Recharging your eSIM with Vostra is a simple process:
- Log in to the Vostra app.
- Go to the My eSIMs section.
- Select the eSIM you wish to recharge.
- Click Recharge and choose a suitable top-up plan.
If needed, you can also download a new eSIM. This option is ideal if your current plan does not include a top-up.
3 steps to streamline your data usage

Here are a few simple tips to avoid running out of data while traveling:
- Download your eSIM before you leave: This ensures you’re connected as soon as you arrive, without wasting time.
- Plan for enough data: If you plan on streaming, sharing large files, or using data-intensive apps, purchase a plan suited to your needs.
- Opt for a regional or global plan: If you’re traveling to multiple countries, choose an eSIM with broad coverage to avoid additional fees.
