The Samsung Galaxy S24 and S25 series are among the most popular Android phones for international travelers. Both fully support eSIM alongside a physical nano-SIM, giving you dual SIM capability. This guide walks you through setting up a travel eSIM on your Galaxy S24 or S25.
Before You Start
Make sure you have:
- A Samsung Galaxy S24, S24+, S24 Ultra, S25, S25+, or S25 Ultra
- Your phone is carrier-unlocked (if bought through a carrier, request unlock first)
- A WiFi connection (needed to download the eSIM profile)
- Your TripoSIM QR code (received via email after purchase)
- Latest software update installed (Settings > Software update)
Step-by-Step Installation
Step 1: Open SIM Manager
Go to Settings > scroll down to Connections > tap SIM Manager (or SIM card manager on older software versions).
Step 2: Add eSIM
Tap Add eSIM. Your phone will show the option to add a new eSIM profile.
Step 3: Choose QR Code Method
Select Scan QR code from service provider. The camera viewfinder will open.
Step 4: Scan the QR Code
Hold your phone over the TripoSIM QR code. You can display the QR code on another device screen or print it from your email. The phone will automatically detect and read the code.
Step 5: Confirm the Download
A confirmation screen will appear showing the carrier details. Tap Add to begin downloading the eSIM profile. This typically takes 30-60 seconds.
Step 6: Name Your eSIM
Samsung will ask you to name the profile. Choose something descriptive like Travel Data, Japan Trip, or Europe eSIM. This makes it easy to identify later.
Step 7: Configure Default SIM Settings
After installation, Samsung will ask which SIM to use for:
- Mobile data: Select your travel eSIM
- Calls: Select your home SIM (to keep your number for calls)
- Messages: Select your home SIM
Step 8: Activate When Ready
You can install the eSIM days before your trip. When you arrive at your destination:
- Go to Settings > Connections > SIM Manager
- Tap your travel eSIM
- Toggle it ON
- Make sure Mobile data is set to the travel eSIM
Samsung-Specific Tips
Use Samsung Internet or Chrome for QR scanning. If the built-in scanner does not work, open the QR code image in your email and take a screenshot, then use Google Lens to scan it.
One UI SIM switching. Samsung's One UI makes it easy to switch data between SIMs. Pull down the notification shade, tap the SIM icon, and select which SIM handles data.
Dual SIM always on. Samsung supports Dual SIM Dual Standby (DSDS), meaning both your home SIM and travel eSIM can be active simultaneously. You receive calls on your home number while using data on the travel eSIM.
Quick Share still works. Samsung Quick Share uses WiFi Direct and Bluetooth, not cellular data, so it works regardless of your SIM configuration.
Samsung Wallet integration. Your eSIM profiles are backed up to your Samsung account. However, travel eSIM QR codes are single-use, so you cannot transfer them to a new device from a backup.
Configuring Data Roaming for eSIM
Your travel eSIM needs data roaming enabled (this is normal — the eSIM connects to local partner networks):
- Go to Settings > Connections > SIM Manager
- Tap your travel eSIM
- Enable Data roaming for the eSIM
At the same time, make sure data roaming is OFF for your home SIM to avoid charges:
- Tap your home SIM in SIM Manager
- Disable Data roaming
How to Remove a Travel eSIM After Your Trip
- Go to Settings > Connections > SIM Manager
- Tap the travel eSIM you want to remove
- Tap Remove at the bottom
- Confirm removal
Note: Once removed, the eSIM profile is permanently deleted. You cannot reinstall it with the same QR code.
How Many eSIMs Can Galaxy S24/S25 Hold?
Samsung Galaxy S24 and S25 phones can store up to 5 eSIM profiles at a time. Only one eSIM can be active for data alongside your physical SIM. This means frequent travelers can pre-install eSIMs for multiple upcoming destinations and just activate the right one on arrival.
Troubleshooting
"Unable to add eSIM" error:
- Ensure you are connected to WiFi
- Check that your phone is carrier-unlocked
- Restart your phone and try again
- Make sure you have not already installed this QR code on another device
No data connection after activation:
- Verify the eSIM is toggled ON in SIM Manager
- Check that Mobile data is set to the travel eSIM
- Enable Data roaming for the travel eSIM
- Toggle Airplane mode on, wait 10 seconds, then off
- Restart your phone
Slow data speeds:
- Go to SIM Manager > travel eSIM > Network mode > select LTE/5G
- Move to a different location (network congestion)
- Toggle airplane mode to force reconnection to a different tower
Home SIM calls not working:
- Ensure your home SIM is still set as default for Calls and Messages in SIM Manager
- Check that your home SIM is active (not disabled)
