To check, take a look at our article: eSIM compatibility for mobile phones . There, you will find an updated list of compatible devices and steps to check if yours is included.

Advantages of using an eSIM for traveling

Opting for an eSIM card for travelling offers numerous advantages over traditional methods such as roaming or SIM cards:

• eSIMs are often cheaper than international data roaming rates .
• Forget about searching for local phone shops and SIM card sales outlets. With the eSIM, you can activate your data plan anywhere, anytime. 
• With many eSIM-compatible phones, you can keep your regular number.
• If your device is lost or stolen, you can remotely deactivate the eSIM, protecting your data and avoiding unwanted charges.

How to choose the best eSIM for your travels?

Selecting the right eSIM for your trip involves considering certain key factors :

1. Make sure the provider operates in all the countries you plan to visit . 
2. If your itinerary includes multiple destinations, look for plans with regional or global coverage .
3. Choose a plan that suits you , without having to pay for more days or limit your consumption.
4. Think about your browsing activities : do you use social media a lot? Do you make frequent video calls? Do you handle large files?
5. If you're unsure about usage, consider an unlimited plan to avoid being left offline .
6. Compare prices from suppliers , but don't just go by the lowest cost.
7. Consider the value for money : A more expensive plan with unlimited data might be more beneficial than several cheap plans with limited data.
8. Review hidden costs , such as activation fees or additional data charges.
9. Check that your phone supports eSIM technology and confirm this information with your carrier. 

We also leave you with a couple of extra recommendations depending on the purpose of your trip: 

• For travel : Prioritize plans with enough data to navigate, use maps, and share content on social media.
• For business travel : Go for plans with unlimited data or large amounts of data to get a stable and reliable connection.
• For study abroad : choose long-term alternatives with abundant data to cover both academic and personal needs.

On the other hand, to avoid disconnecting at crucial moments, the trick is to buy a prepaid data plan with a little more than you think you will need. For example:

• For a week-long trip with moderate usage, a 5-15GB plan should be sufficient.
• For trips of two weeks or more , especially if you'll be streaming video frequently or actively going online, plans of 30GB and up will be a good fit.
• For long stays or if, in short, you want to browse with total freedom, unlimited data plans, such as those from Olysim, are the answer.

How to save data?

Remember that you can implement strategies to save data on your mobile devices , including:

1. When using mobile data disable automatic app updates.
2. Use “lite” versions of popular apps, designed to consume less data.
3. Download maps, music, or content for offline use when you have access to Wi-Fi.
4. Adjust streaming quality in video and music apps to reduce data usage.
