Using a Sri Lanka eSIM on an Android phone is a convenient way to get mobile data without replacing your regular SIM card. You can install the travel eSIM before departure, keep your primary number active and connect to a supported local network after arriving in Sri Lanka.
Mobile data is useful throughout the island, whether you are visiting Colombo, Kandy, Sigiriya, Ella, Galle, Mirissa, Nuwara Eliya, Trincomalee or Arugam Bay. You can use your connection for Google Maps, WhatsApp, hotel communication, ride-hailing apps, train information, restaurant searches and travel bookings.
Many recent Samsung Galaxy, Google Pixel, Motorola, Xiaomi, Honor, Oppo and other Android devices support eSIM technology. However, compatibility varies by model, country of purchase, software version and mobile operator.
Quick answer: install your Sri Lanka eSIM while connected to reliable WiFi. After landing, enable the eSIM, select it for Mobile Data, turn on Data Roaming and keep automatic data switching turned off.
Top Sri Lanka eSIMs
Can You Use an eSIM on Android in Sri Lanka?
Yes. A compatible and unlocked Android phone can use a travel eSIM in Sri Lanka. The eSIM connects to a supported local partner network and provides mobile internet during the validity period of your selected plan.
You usually do not need to remove your regular physical SIM. Dual SIM Android phones can keep the primary line active for calls and SMS while using the Sri Lanka eSIM for mobile data.
NoveSIM Sri Lanka plans are data-only. They do not include a traditional Sri Lankan phone number, standard voice minutes or SMS. You can still make calls and send messages through internet-based applications such as WhatsApp, Viber, Messenger, Telegram, Google Meet and Microsoft Teams.
Which Android Phones Support eSIM?
eSIM support is available on many recent premium and selected mid-range Android smartphones. Compatibility cannot be confirmed by the brand name alone because different versions of the same device may have different SIM configurations.
| Android Brand | General eSIM Availability |
|---|---|
| Samsung Galaxy | Available on many recent Galaxy S, Z Fold, Z Flip and selected other models |
| Google Pixel | Available on many Pixel models |
| Motorola | Available on selected Razr, Edge and other compatible models |
| Xiaomi | Available on selected international flagship and newer models |
| Honor | Available on selected compatible models |
| Oppo | Available on selected Find and other supported models |
| Sony Xperia | Available on selected regional models |
| Other Android brands | Check the exact model number and device settings |
A phone model sold in Europe may support eSIM while a version sold in another market may not. Always check the exact model number, region and available settings before buying a travel eSIM.
How to Check Whether Your Android Phone Supports eSIM
The easiest method is to look for an eSIM installation option in your device settings.
On many Samsung phones:
- Open Settings.
- Select Connections.
- Tap SIM Manager.
- Look for Add eSIM.
On Google Pixel and other stock Android devices:
- Open Settings.
- Select Network and Internet.
- Tap SIMs or the plus symbol beside SIMs.
- Look for an option to download or add an eSIM.
Depending on the manufacturer, the option may be called:
- Add eSIM.
- Add Mobile Plan.
- Download a SIM.
- Add SIM.
- Set Up an eSIM.
- Download New eSIM.
You can also open the phone dialer and enter *#06#. If an EID appears together with the IMEI numbers, the phone usually includes eSIM hardware. However, the settings menu remains the most practical compatibility check.
Read our full guide to checking whether your phone supports a Sri Lanka eSIM.
Make Sure Your Android Phone Is Unlocked
An Android phone may support eSIM technology but still be locked to the mobile operator that sold it. A carrier-locked device may reject an international travel eSIM or prevent it from connecting to partner networks.
The lock status is not displayed consistently across all Android brands. You can check it by:
- Contacting your home mobile operator.
- Checking the original purchase agreement.
- Looking for Network Lock or SIM Lock in the settings.
- Testing the phone with a SIM card from another operator.
If you are unsure, contact your provider before purchasing the eSIM. Unlocking requirements and waiting periods depend on the operator and contract.
Why Use a Sri Lanka eSIM on Android?
- Install your mobile data plan before departure.
- No need to replace your physical SIM card.
- Avoid queues at airport mobile operator counters.
- Keep your existing number available for calls and SMS.
- Connect shortly after arriving in Sri Lanka.
- Manage both SIM lines from the Android settings.
- Continue using WhatsApp with your existing number.
- Choose a data plan based on your trip length.
An eSIM is particularly useful for short holidays, backpacking trips, road trips, business travel and journeys covering several destinations in Sri Lanka.
What You Need Before Installing the eSIM
Prepare the following before starting the installation:
- A compatible and unlocked Android smartphone.
- A reliable WiFi connection.
- Your eSIM QR code or installation link.
- The manual installation details if provided.
- An updated version of Android.
- Enough battery power to complete the setup.
Your NoveSIM QR code and installation instructions are delivered by email after purchase. The same details can also be found in your NoveSIM account by opening your order and viewing the eSIM information.
When Should You Install Your Sri Lanka eSIM?
Install the eSIM before departure while connected to stable WiFi. This gives you time to confirm that the profile appears correctly in your SIM settings and resolve any installation issue before travelling.
Installing an eSIM and activating the data plan are not always the same event. Depending on the selected package, the plan commonly begins when the eSIM first connects to a supported network in Sri Lanka.
Do not delete the eSIM after installation. Many travel eSIM QR codes can only be used once and may not support a second installation after the profile has been removed.
How to Install a Sri Lanka eSIM on Samsung
The menu names may vary slightly depending on the Samsung model and One UI version.
- Connect the phone to stable WiFi.

- Choose Scan QR Code.
- Scan the QR code supplied after purchase.

- Find Mobile Network, SIMs, SIM Manager or Network and Internet.
- Select Add eSIM or a similar option.
- Choose the QR code installation method.
- Scan the supplied QR code.
- Confirm the installation.
- Label the new mobile plan.
Use the settings search field and search for eSIM when you cannot find the correct menu manually.
How to Install the Sri Lanka eSIM Manually
If QR code scanning is unavailable, you may be able to install the profile with the SM-DP+ address and activation code supplied with your order.
- Open the eSIM installation menu.
- Select the manual entry option.
- Enter the supplied SM-DP+ address.
- Enter the activation code exactly as provided.

A missing character, extra space or incorrect symbol can prevent installation. Copy the information exactly and use stable WiFi throughout the process.
Recommended Settings During Installation
Your Android phone may ask which SIM should be used for calls, messages and mobile data.
| Setting | Recommended Choice |
|---|---|
| Calls | Primary SIM |
| SMS | Primary SIM |
| Mobile Data before arrival | Primary SIM or off |
| Mobile Data after arrival | Sri Lanka eSIM |

Data Roaming must be enabled on the travel eSIM because it connects through a supported local partner network. This does not mean that roaming should also be enabled on your primary SIM.
Recommended Android Settings in Sri Lanka

See our full guide to Sri Lanka eSIM APN settings.
Which Mobile Network Will Your Android Phone Use?
A travel eSIM connects through one or more supported local partner networks in Sri Lanka. The exact operator depends on the selected plan and its roaming agreements.
Automatic Network Selection is normally recommended because it allows the phone to register with an available supported network. Coverage is generally strongest in Colombo, Kandy, Galle and other populated locations.
Signal quality can vary in Ella, Nuwara Eliya, national parks, mountain roads and isolated coastal destinations. Download offline maps before travelling through areas where coverage may be inconsistent.
Read our comparison of the best mobile networks in Sri Lanka for tourists.
Should You Use 5G or 4G?
If your device, plan and local network support 5G, the phone may connect automatically. For most users, the default 5G Auto setting provides a good balance between speed and battery consumption.
Switch to 4G or LTE when:
- The 5G signal is weak.
- The connection repeatedly disconnects.
- The phone battery is draining quickly.
- 4G provides a more stable signal.
A strong 4G connection is sufficient for maps, messaging, browsing, ride-hailing and most normal travel activities.
Does WhatsApp Work with a Sri Lanka eSIM?
Yes. WhatsApp continues to use your existing phone number even when the Sri Lanka eSIM provides mobile data.
You do not need to change the number registered with WhatsApp. Continue using your current account for messages, voice calls and video calls.
If WhatsApp asks whether you want to register a new number after installing the eSIM, keep your existing number unless you intentionally want to change the account.
Learn more in our guide to using WhatsApp in Sri Lanka.
Can You Use Personal Hotspot on Android?
Hotspot availability depends on the selected eSIM plan and device. When supported, you can share mobile data with a laptop, tablet or another phone.
On Samsung and many other Android phones:
- Open Settings.
- Select Connections or Network and Internet.
- Open Mobile Hotspot and Tethering or Hotspot and Tethering.
- Enable Mobile Hotspot.
Hotspot use can consume data quickly. Laptops may automatically download software updates, synchronise files or back up photographs after connecting.
How to Reduce Mobile Data Usage on Android
- Download offline Google Maps.
- Enable Data Saver.
- Disable automatic application updates over mobile data.
- Pause Google Photos and cloud backups.
- Reduce video streaming quality.
- Disable social media video autoplay.
- Download music and entertainment over WiFi.
- Restrict background data for unnecessary applications.
To enable Data Saver:
- Open Settings.
- Select Connections or Network and Internet.
- Open Data Usage or Data Saver.
- Enable the data-saving option.
What to Do If the Sri Lanka eSIM Is Not Working
Check the main settings before deleting or reinstalling the profile.

What If the Phone Shows No Service?
No Service usually means that the Android phone has not registered with a supported local network.
- Confirm that you are already in Sri Lanka.
- Enable the travel eSIM.
- Turn on Data Roaming.
- Use Airplane Mode for 30 seconds.
- Restart the device.
- Keep Network Selection on Automatic.

If automatic network selection fails, test a supported network manually.

- Disable automatic selection.
- Wait for the available networks to appear.

- Wait several minutes for registration.
Return to automatic selection if the manually selected network does not provide a stable connection.
Can You Transfer the eSIM to Another Android Phone?
A travel eSIM is normally intended for installation on one device. Standard Android eSIM transfer tools may not work with a travel profile.
Install the eSIM on the phone you plan to carry during the trip. Do not test it on one device if you intend to use it on another.
Can You Delete and Reinstall the eSIM?
Do not delete the eSIM unless customer support specifically instructs you to do so. Many travel eSIM QR codes are valid for one installation only.
Disabling an eSIM is different from deleting it. You can turn the line off temporarily and enable it again later without removing the profile.
