Using a Sri Lanka eSIM on your iPhone is one of the easiest ways to get mobile data during your trip. You can install the eSIM before departure, keep your regular SIM active and connect to a supported local network after landing.
A travel eSIM is useful when visiting Colombo, Kandy, Ella, Sigiriya, Galle, Mirissa, Nuwara Eliya, Trincomalee or Arugam Bay. It gives you internet access for Google Maps, WhatsApp, hotel communication, train information, ride-hailing apps and travel bookings.
Most recent iPhone models support eSIM technology, but compatibility can depend on the model, country of purchase and whether the phone is locked to a mobile operator.
Quick answer: install your Sri Lanka eSIM while connected to WiFi, then after landing select it for Mobile Data, enable Data Roaming and keep Automatic Data Switching turned off.

Can You Use an eSIM on an iPhone in Sri Lanka?
Yes. You can use a travel eSIM on a compatible and unlocked iPhone in Sri Lanka. The eSIM connects to a supported local partner network and provides mobile data throughout the plan validity period.
You do not need to remove your regular SIM card. Most compatible iPhones allow you to keep your primary line active for calls and SMS while using the Sri Lanka eSIM for mobile internet.

The presence of an EID usually confirms that the device includes eSIM technology.
Read our complete guide to checking whether your phone supports a Sri Lanka eSIM.
Make Sure Your iPhone Is Unlocked
An iPhone may support eSIM technology but still be locked to the mobile operator that originally sold it. A carrier-locked phone may reject an international travel eSIM.
To check the lock status:
- Open Settings.
- Select General.
- Tap About.
- Find Carrier Lock or Network Provider Lock.
If the device shows No SIM Restrictions, it is normally unlocked. If another message appears, contact your home mobile operator before purchasing an eSIM.
Why Use a Sri Lanka eSIM on iPhone?
- Install the plan before departure.
- No physical SIM card replacement is required.
- Avoid airport SIM card queues.
- Keep your regular SIM active.
- Use mobile data shortly after landing.
- Switch between mobile lines from the iPhone settings.
- Use WhatsApp with your existing number.
- Choose a plan based on the length of your trip.
An eSIM is especially useful for short holidays, business trips, backpacking routes and multi-city journeys across Sri Lanka.
What You Need Before Installation
Prepare the following before installing your Sri Lanka eSIM:
- A compatible and unlocked iPhone.
- A stable WiFi connection.
- Your eSIM QR code or installation link.
- The installation details received after purchase.
- The latest available iOS update.
- Enough battery power to complete the setup.
Your NoveSIM QR code and installation instructions are sent by email after purchase. You can also find the eSIM information in your NoveSIM account by opening your order and viewing the eSIM details.
When Should You Install Your Sri Lanka eSIM?
Install the eSIM before departure while you still have access to reliable WiFi. This gives you time to complete the setup and check that the new mobile line appears correctly in your iPhone settings.
Installing the eSIM does not always mean that the data plan starts immediately. Activation conditions depend on the selected package. Travel plans commonly begin when the eSIM first connects to a supported network in the covered destination.
Do not delete the eSIM after installation. Many QR codes are intended for one installation and may not work again after the profile has been removed.
How to Install a Sri Lanka eSIM on iPhone with a QR Code
- Connect your iPhone to stable WiFi.
- Open Settings.
- Select Cellular or Mobile Data.
- Tap Add eSIM.
- Select Use QR Code.
- Scan the QR code received after purchase.
- Tap Continue when the mobile plan is detected.
- Wait for the eSIM to be added.
- Label the new line Sri Lanka, Travel or NoveSIM.
If the QR code is displayed on the same iPhone, open it on another screen or use the installation link when available.
How to Install the eSIM with an Installation Link
Some eSIM orders include a direct installation link. When supported, open the link on the iPhone and follow the on-screen instructions.
- Connect the iPhone to WiFi.
- Open the installation link on the device.
- Allow the iPhone to add the mobile plan.
- Confirm the installation.
- Label the new mobile line.
Do not share the installation link or QR code with another person. An eSIM is generally intended for installation on one compatible device.
How to Install the Sri Lanka eSIM Manually
If QR code scanning is not possible, manual installation may be available using the SM-DP+ address and activation code supplied with the order.
- Open Settings.
- Select Cellular or Mobile Data.
- Tap Add eSIM.
- Select Use QR Code.
- Choose Enter Details Manually.
- Enter the supplied SM-DP+ address.
- Enter the activation code.
- Complete the installation.
Copy the information exactly. Additional spaces or missing characters may prevent the profile from being downloaded.
Recommended iPhone Settings During Installation
During the setup, your iPhone may ask you to select default lines for calls, messages and mobile data.
| Setting | Recommended Choice |
|---|---|
| Default Voice Line | Primary SIM |
| iMessage and FaceTime | Primary SIM |
| Mobile Data | Sri Lanka eSIM after arrival |
| Allow Mobile Data Switching | Off |
You can keep your primary SIM selected during installation and change the Mobile Data line after landing in Sri Lanka.
How to Activate the Sri Lanka eSIM After Landing
After arriving in Sri Lanka, configure the iPhone to use the travel eSIM for mobile internet.
- Open Settings.
- Select Cellular or Mobile Data.
- Tap the Sri Lanka eSIM.
- Enable Turn On This Line.
- Turn Data Roaming on.
- Return to the Cellular or Mobile Data menu.
- Select Cellular Data or Mobile Data.
- Choose the Sri Lanka eSIM.

Data Roaming must be enabled on a travel eSIM because it connects through a supported local partner network.
Recommended iPhone Settings in Sri Lanka

How to Avoid Roaming Charges on Your Primary SIM
Keeping your regular SIM active is useful for receiving SMS verification codes and incoming calls. However, incorrect settings may allow your home SIM to use mobile data abroad.
To reduce the risk of unexpected charges:
- Open Settings.
- Select Cellular or Mobile Data.
- Tap your primary SIM.
- Turn Data Roaming off.
- Return to the Mobile Data menu.
- Confirm that the Sri Lanka eSIM is selected for data.
- Turn Allow Cellular Data Switching off.
Your home mobile operator may still charge for incoming or outgoing calls while roaming. Check its international pricing before travelling.
Sri Lanka eSIM APN Settings on iPhone
The APN is normally configured automatically. If the iPhone connects to a mobile network but does not load websites or apps, manual APN configuration may be required.
| APN Field | Value |
|---|---|
| Cellular Data APN | data.esim |
| Username | Leave blank |
| Password | Leave blank |
| Personal Hotspot APN | data.esim if required |
To check the APN:
- Open Settings.
- Select Cellular or Mobile Data.
- Tap the Sri Lanka eSIM.
- Open Cellular Data Network or Mobile Data Network.
- Enter data.esim in the APN field.
- Leave the username and password blank.
- Return to the previous menu to save the settings.
The Cellular Data Network menu may not appear on every iPhone or mobile profile. When it is unavailable, the APN is usually managed automatically.
See our full guide to Sri Lanka eSIM APN settings.
Which Mobile Network Will the iPhone 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 recommended because it allows the iPhone to connect to an available supported network.
Mobile coverage is generally strongest in Colombo, Kandy, Galle and other populated locations. Signal may be less consistent in mountain regions, national parks and remote coastal areas.
Learn more in our comparison of the best mobile networks in Sri Lanka for tourists.
Should You Use 5G Auto or LTE?
If 5G is available and supported by the plan, the iPhone may connect automatically when 5G Auto is selected.
For most tourists, 5G Auto is a good default because the iPhone can balance network performance and battery usage. If the connection is unstable, switch temporarily to LTE.
- Open Settings.
- Select Cellular or Mobile Data.
- Tap the Sri Lanka eSIM.
- Select Voice and Data.
- Choose 5G Auto or LTE.
A strong LTE connection may provide better performance than a weak 5G signal, especially outside major cities.
Can You Use WhatsApp with a Sri Lanka eSIM?
Yes. WhatsApp continues to use your existing phone number even when mobile data is provided by the Sri Lanka eSIM.
Do not change your WhatsApp number when the app asks whether you want to use the new SIM information. Your account, conversations and contacts can remain connected to your regular number.
You can use WhatsApp messages, voice calls and video calls through the eSIM data connection.
Read our guide to using WhatsApp in Sri Lanka.
Can You Keep iMessage and FaceTime Active?
Yes. Keep your primary phone number or Apple Account selected for iMessage and FaceTime. The Sri Lanka eSIM can provide the internet connection without changing your usual iMessage identity.
If the iPhone asks whether you want to update your trusted number or iMessage settings, keep your existing number unless you specifically want to change it.
Can You Use Personal Hotspot?
Personal Hotspot availability depends on the selected eSIM package and network conditions. If hotspot is supported, you can share the connection with a laptop, tablet or another device.
To enable Personal Hotspot:
- Open Settings.
- Select Personal Hotspot.
- Enable Allow Others to Join.
If the Personal Hotspot option is unavailable, check that the Sri Lanka eSIM is selected for mobile data and enter data.esim in the Personal Hotspot APN field when that menu is available.
Hotspot use can consume data quickly. Software updates, video meetings and cloud backups may use several gigabytes.
How to Use Less Mobile Data on iPhone
- Download offline Google Maps before travelling.
- Enable Low Data Mode for the Sri Lanka eSIM.
- Disable automatic app downloads.
- Pause iCloud Photos uploads on mobile data.

- Keep Network Selection on Automatic.
- Confirm that the APN is data.esim.

Try the following:

- Enable the eSIM line.
- Turn Data Roaming on.
- Use Airplane Mode for 30 seconds.
- Restart the device.

- Tap the Sri Lanka eSIM.
- Select Network Selection.
- Turn Automatic off.
- Wait for available networks to appear.
- Select a network supported by the eSIM plan.
Return to Automatic Network Selection if the manually selected network does not connect.
Can You Transfer the eSIM to Another iPhone?
A travel eSIM is normally intended for one device and may not support Apple’s standard eSIM transfer process. Do not install it on one iPhone if you plan to use it on another.
Check device compatibility before installation and keep the eSIM on the same iPhone throughout the trip.
Can You Delete and Reinstall the Sri Lanka eSIM?
Do not delete the profile unless customer support specifically instructs you to do so. Many travel eSIM QR codes can only be installed once.
Turning the line off is different from deleting it. You can disable the eSIM temporarily and enable it again later without removing the profile.
