What happens if I run out of data?

Running out of data while traveling can be one of the most frustrating experiences — especially when you’re in a new country relying on mobile internet to navigate, communicate, access bookings, and stay connected. If you run out of data on your eSIM during an important moment, your online activities can suddenly stop, leaving you stuck without directions, unable to message friends or family, or even unable to check transport schedules.

Understanding what happens when you run out of data, what options you have to get back online, and how to avoid running out completely will help you travel smarter and prevent stress during important moments. This guide breaks down everything you need to know when you run out of data on your eSIM — including top-up options, installing a new eSIM, and smart usage tips to keep your trip smooth.

What Happens When You Run Out of Data

When your eSIM data balance hits zero, your internet connection usually stops or slows significantly, depending on your provider’s policy. Some eSIM plans automatically reduce internet speed to a lower tier (for example, throttled 2G speeds), while others cut off access completely.

In either case, you won’t be able to browse smoothly, use maps in real time, or load apps that require stable connections. That’s why understanding your options for topping up or installing a new plan is essential.

Option 1: Top Up Your Existing eSIM Plan

One of the easiest solution when you run out of data is purchasing an add-on or top-up. This lets you keep using your current eSIM without reinstalling anything.

Here’s how to top up:

1. Open your eSIM provider’s app or website – navigate to your account or “My eSIMs” section.
2. Select the eSIM plan that has run out of data.
3. Look for a “Top Up” or “Add-on” option – this is where you can buy extra data.
4. Purchase a suitable data package – once confirmed, your data will refresh, and you can continue using your eSIM seamlessly.

This method is perfect if your provider supports extensions and you prefer to keep the same number or configuration. Unfortunately, at the moment, you cannot renew the data on your Twise eSIM. However, you can purchase another eSIM if you need more data.

Option 2: Install a New eSIM Plan

If your current plan doesn’t offer add-ons, you can simply install a new eSIM.

Here’s what to do:

• Choose a new data plan from your existing provider or explore options from another provider for better coverage.
• Follow the same activation steps you used initially to set it up.
• Switch your device’s data line to the new eSIM in your settings.

Many travelers choose to install more than one eSIM in advance so switching is instant if they run out of data.

Important Tips to Avoid Sudden Disconnection

• Check your plan’s terms: Some plans don’t support top-ups — knowing this upfront saves time.
• Track your usage: Reset your phone’s data statistics before your trip to monitor real-time consumption.
• Be mindful of heavy apps: Video streaming, cloud backups, and background updates can eat through data fast.

Twise Travel Tips

From our experiences, running out of data usually happens at the worst times – like when navigating a foreign subway system or translating directions on the go.

Pro Tip: If you’re on a longer trip, consider pre-purchasing a backup regional Twise eSIM. This way, even if your main plan runs out, you can instantly switch without losing connectivity.

Conclusion

Running out of data doesn’t have to disrupt your travels. Whether you top up your existing plan or install a new eSIM, regaining a stable connection is quick and simple. By staying aware of your usage and having a backup option ready, you can avoid slow speeds and keep your journey running smoothly.
