How to Switch to an International Travel eSIM Without Losing Your Number

Jul 17, 2025

Are you planning to travel to a different country? One of the major concerns is staying connected while overseas, and maintaining your number. Fortunately, you can keep your phone number when switching to an international travel eSIM.


What Is An E-SIM?

An eSIM is a digital counterpart of a SIM card. As with traditional SIM cards, it links your device to a mobile network, but only through a mobile wired connection, it is integrated into your device.

You do not have to remove or add anything. Installation is done through QR codes or apps. It can start functioning soon after setup.


What Is an International Travel eSIM

The best eSIM for international travel allows you to connect to mobile networks when you are abroad. Instead of paying exorbitant roaming fees, you can utilise a local or global data plan through an international travel eSIM, ensuring convenience and cost-efficiency during your trips.

International travel eSIMs help in avoiding the cumbersome process of SIM card purchases in shops or airports.


2. Decide What You Want to Keep  

Ask yourself the following questions:  

  • Would you like to retain your current number solely for receipt of calls and texts?  

  • Will you need mobile data in the country you are visiting?  

This helps you have a better travel plan in place.  


3. Purchase an eSIM for Travel  

Pick a plan that matches your travel destination and the duration of stay. You can access many options that cover one or more countries.  


4. Install the eSIM  

Upon purchasing the eSIM, you will receive either a QR code or setup details. Scan it with your phone's settings. The eSIM installation will take a few minutes.  


5. Configure Data Settings  

Configure your phone to use the eSIM for mobile data. You can retain your SIM for calls and SMS as the default.  

This is where you retain your phone number with eSIM and use local data for other functions.  


6. Test Before You Travel  

Confirm that your device would be able to switch between the two SIMs seamlessly. Always check your configurations before your trip.  


Advantages of Keeping Your Phone Number While Using an eSIM  

·      No need to do a SIM swap: Your physical SIM does not need to be removed.  

·      Stay reachable: All your calls and messages come through on your main number.  

·      Save money: Avoid costly roaming charges by using local data rates.  

·      Quick setup: Skip long lines for a SIM card.  

·      Easy switching: Change networks with a few taps.  


Tips for a Smooth eSIM Experience   

Use Wi-Fi First  

For downloading and installing eSIM, always use Wi-Fi. It’s faster.

Keep Your SIM PIN Handy  

Switching network settings might require your SIM PIN.  

Check Network Compatibility  

Ensure that your eSIM provider will be able to access networks in the country you’re visiting.  

Manage Data Wisely  

Use data monitoring tools or set stringent limits to ensure controlled spending.  

Common Use Cases  

  • Business travel where immediate access to office resources is crucial.

  • Family vacations when staying in touch with family are important.  

  • Digital nomads who are always travelling but are still connected to work.  

  • Out-of-state students who wish to maintain their home number while wanting local data.  

Switching to an international travel eSIM is the right choice.


Conclusion  

Using a Travel Wifi eSIM for international travel does not automatically forfeit your number. You can enjoy local data rates while staying connected to friends and family back home.

It is simple to set up and incredibly convenient for travelling. You don't need to visit any physical stores or manage physical SIMs. The best part is that you retain your phone number on eSIM during the entire process.
