Travel data. Made simple.

An eSIM is a digital SIM card already built into many newer phones. Instead of inserting a physical SIM card, you install your data package digitally directly on the device. This makes it faster and easier to get online, especially when travelling.

Most newer smartphones support eSIM, but it depends on the model, manufacturer and whether the phone is carrier-unlocked. It's a good idea to check if your device is eSIM-compatible before purchasing, so you avoid surprises and can be sure everything works as expected.

Your plan only starts when you use data at your destination. Installing doesn't start it, so you can install now and leave the eSIM until you land.

Your plan only starts when you use data at your destination.

Yes, in many cases you can keep your regular number on your primary SIM while using the eSIM for data. This gives you a flexible setup where you can still receive messages and use your normal number, while avoiding expensive roaming charges.

Yes, MondoMate supports hotspot and tethering. You can share your mobile data with a laptop, tablet or another phone. Shared data is deducted from your package.

Estimate your data needs based on how you use your phone while travelling.

Start by checking whether your phone supports eSIM, whether it's unlocked for other networks, and whether the installation was completed correctly. If that doesn't help, the issue is often resolved by activating the right line, enabling data roaming, restarting the phone or checking APN settings.

For many travellers, yes. eSIM often makes it easier to get data quickly and can be a more transparent and affordable alternative to traditional roaming. You also avoid having to swap a physical SIM card, making the whole experience simpler.

No, in most cases you don't need to remove your current SIM card. Many phones can have both a physical SIM and an eSIM active at the same time, so you can keep your regular number and use the eSIM for data while travelling.

Your plan only starts when you use data at your destination. Installing doesn't start it, so you can install now and leave the eSIM until you land.

When you've used all the data in your package, the connection will normally stop until you buy more data or activate a new package. That's why it can be a good idea to choose a package with a bit of extra room, especially if you're travelling for several days.

Yes, in many cases you can buy extra data or choose a new package if your needs change along the way. This makes eSIM more flexible, since you don't necessarily have to start from scratch if you stay longer or use more data than expected.

It depends on the package you choose. Some eSIMs are valid in only one country, while others cover multiple countries or entire regions. If you're travelling between several destinations, a regional or global plan may be the better choice.

Yes, eSIM is generally a secure solution. Because it's installed digitally directly on your phone, you don't have to handle a physical SIM card that could get lost or damaged. For most users, it simply means a simpler and more modern way to get online.

Yes, many newer phones can store multiple eSIM profiles on the same device. This means you can have several different plans saved and switch between them as needed — which is especially practical if you travel often or use different solutions for different purposes.

No, not in itself. Battery usage depends much more on signal strength, apps, screen usage and network conditions than on whether you're using eSIM or a physical SIM. Poor signal in general can increase power consumption, but that applies to all mobile networks.

This can be a challenge. Even if the phone technically supports eSIM, a carrier-locked device may be restricted to certain networks. It's therefore important to check both eSIM support and whether the phone is open for use with other providers.

eSIM is especially well suited for travellers who want to get online quickly and without hassle. It's a great solution for holidaymakers, business travellers and people who travel across multiple countries and want a more flexible and modern way to manage their data.
