Activating a Canary Islands eSIM is usually straightforward, but installation and activation are not always the same thing. You can often install the eSIM before departure, while the mobile data plan becomes active only after the phone connects to a supported network in the Canary Islands.
The exact activation process depends on the plan, phone model and activation policy. Some eSIM plans begin when they first connect to a local network, while others may start immediately after installation or on a selected date.
To avoid losing part of the validity period, read the activation instructions before turning on the travel line. Install the eSIM on stable WiFi, keep it stored on the phone and complete the final mobile data settings after arrival.
Quick answer: Install the eSIM before travelling, but do not activate it too early when the validity starts immediately. After arriving in the Canary Islands, enable the eSIM, select it for mobile data, turn on Data Roaming and disable automatic data switching. If internet does not work, check that the APN is set to data.esim.

What Does eSIM Activation Mean?
eSIM activation can refer to several different steps, which often causes confusion.
- Purchase: You order the data plan and receive installation details.
- Installation: You add the eSIM profile to your phone.
- Line activation: You turn on the travel eSIM in the phone settings.
- Network activation: The eSIM connects to a supported local network.
- Plan validity: The data package begins counting down according to its activation policy.
These steps may happen at different times. Installing the eSIM before departure does not always mean the data package has already started.
When Should You Activate a Canary Islands eSIM?
The safest approach is to install the eSIM before departure and activate the mobile data connection after arrival, unless the plan instructions state otherwise.
| Activation Policy | When the Plan Starts | Recommended Action |
|---|---|---|
| First network connection | When the eSIM connects in the destination | Install before travel and enable after arrival |
| Immediately after installation | As soon as the profile is added | Install close to departure |
| Selected activation date | On the date chosen during purchase | Confirm the date before travelling |
| Manual activation | When the user activates the plan | Follow the provider instructions carefully |
Always check the product details because activation rules can vary between plans.
What You Need Before Activation
Prepare the following before installing or activating the eSIM:
- An unlocked eSIM-compatible phone.
- A stable WiFi connection.
- The QR code or manual installation details.
- The exact plan activation instructions.
- Enough battery power.
- Access to the purchase email or account.
- The correct APN details if manual configuration is required.
Do not begin installation with an unstable connection because the phone must download the eSIM profile successfully.
Check Whether Your Phone Supports eSIM
Before purchasing or activating the plan, confirm that the phone supports eSIM.
On iPhone:
- Open Settings.
- Select Cellular or Mobile Service.
- Look for Add eSIM.
On Android:
- Open Settings.
- Search for eSIM, SIM Manager or Add SIM.
- Look for an option to add or download an eSIM.
You can also dial:
*#06#
If the phone displays an EID, it usually supports eSIM.
Check Whether the Phone Is Unlocked
A carrier-locked phone may reject a travel eSIM even when the device supports the technology.
On iPhone:
- Open Settings.
- Select General.
- Select About.
- Find Carrier Lock.
If the status shows No SIM restrictions, the phone is generally unlocked.
On Android, the lock status may not appear clearly. Contact the original operator or test another operator’s SIM before travelling.
How to Install the eSIM Before Departure
Install the profile while connected to stable WiFi.
- Open the eSIM installation email or account page.
- Display the QR code on another device or print it.
- Open the SIM or mobile network settings on the phone.
- Select the option to add an eSIM.
- Scan the QR code.
- Follow the installation prompts.
- Label the new line as NoveSIM, Travel or Canary Islands.
- Keep the eSIM installed until the trip is complete.
Do not scan the QR code on a second phone after installation. Most travel eSIM profiles are intended for one device and one installation.
How to Activate the eSIM After Arrival
After landing in the Canary Islands, complete the following steps:
- Open the mobile network or SIM settings.
- Enable the travel eSIM.
- Select it as the preferred line for mobile data.
- Enable Data Roaming on the travel eSIM.
- Disable automatic mobile data switching.
- Keep Data Roaming disabled on the primary SIM.
- Wait a few minutes for network registration.
- Test the connection with WiFi turned off.
Initial registration may take several minutes, especially immediately after arrival.
How to Activate a Canary Islands eSIM on iPhone
- Open Settings.
- Select Cellular or Mobile Service.
- Select the travel eSIM.
- Turn on Turn On This Line.
- Return to the main Cellular menu.
- Select Cellular Data.
- Choose the travel eSIM.
- Turn off Allow Cellular Data Switching.
- Open the travel eSIM settings again.
- Enable Data Roaming.
| iPhone Setting | Correct Configuration |
|---|---|
| Travel eSIM line | On |
| Cellular Data | Travel eSIM selected |
| Data Roaming | On for travel eSIM |
| Allow Cellular Data Switching | Off |
| Primary SIM Data Roaming | Off |
| APN | data.esim |
How to Activate a Canary Islands eSIM on Android
Android menu names vary by manufacturer, but the process is similar.
- Open Settings.
- Open Connections, Network & Internet or Mobile Network.
- Open SIM Manager or SIMs.
- Enable the travel eSIM.
- Select it as the preferred SIM for mobile data.
- Enable Data Roaming on the travel eSIM.
- Disable automatic data switching.
- Wait for the phone to connect to a supported network.
| Android Setting | Correct Configuration |
|---|---|
| Travel eSIM | Enabled |
| Preferred SIM for mobile data | Travel eSIM |
| Data Roaming | Enabled for travel eSIM |
| Automatic Data Switching | Disabled |
| Primary SIM Data Roaming | Disabled |
| APN | data.esim |
Why Data Roaming Must Be Enabled
Travel eSIMs often connect through local partner networks rather than a network owned directly by the travel eSIM provider. For this reason, Data Roaming usually needs to be enabled on the travel line.
Enabling roaming on the eSIM does not automatically activate roaming on your primary SIM. Each line normally has its own setting.
To avoid unexpected charges:
- Enable Data Roaming only on the travel eSIM.
- Keep it disabled on the primary SIM.
- Select the eSIM as the preferred mobile data line.
- Disable automatic data switching.
How to Set the APN
If the phone connects to a mobile network but internet does not work, check the Access Point Name.
| APN Field | Value |
|---|---|
| Name | NoveSIM |
| APN | data.esim |
| Username | Leave blank |
| Password | Leave blank |
Leave all other fields unchanged unless different details are specifically provided.
How to Set the APN on iPhone
- Open Settings.
- Select Cellular or Mobile Service.
- Select the travel eSIM.
- Select Cellular Data Network when available.
- Enter data.esim in the APN field.
The APN menu may be hidden when the settings are configured automatically.
How to Set the APN on Android
- Open Settings.
- Open the mobile network settings.
- Select the travel eSIM.
- Open Access Point Names.
- Create a new APN.
- Enter NoveSIM as the name.
- Enter data.esim as the APN.
- Save and select the new profile.
How to Know Whether the eSIM Is Active
The eSIM is normally active when:
- The travel line appears enabled in the phone settings.
- A local or partner network name is displayed.
- Signal bars appear for the travel line.
- Mobile data works with WiFi turned off.
- Maps, messaging and websites load successfully.
A network name alone does not always confirm that mobile data is configured correctly. Test the connection by disabling WiFi and opening a webpage.
Does the eSIM Activate Automatically?
Some travel eSIMs activate automatically when they connect to a supported network in the destination. Others require you to turn on the line and configure the mobile data settings manually.
Even when network activation is automatic, you may still need to:
- Select the eSIM for mobile data.
- Enable Data Roaming.
- Disable automatic data switching.
- Enter the APN.
- Restart the phone.
Can You Activate the eSIM Before Arriving?
You may be able to install and enable the line before arrival, but the eSIM may not connect until it reaches a supported network in the Canary Islands.
Avoid turning it on too early when the plan validity begins immediately after activation. Check the instructions first.
If the plan activates only after the first destination network connection, installing it before travel is usually safe.
How Long Does Activation Take?
Installation normally takes only a few minutes when the WiFi connection is stable. Network registration after arrival may take several minutes.
Activation may take longer when:
- The phone has just left Airplane Mode.
- The local network is busy.
- The phone is indoors or underground.
- Automatic network selection is still searching.
- The mobile data settings are incorrect.
- The phone needs to be restarted.
What to Do If the eSIM Does Not Activate
- Confirm that the eSIM appears in the SIM settings.
- Check that the travel line is enabled.
- Select it as the preferred mobile data line.
- Enable Data Roaming on the eSIM.
- Disable automatic data switching.
- Turn WiFi off temporarily.
- Activate Airplane Mode for approximately 30 seconds.
- Turn Airplane Mode off.
- Wait several minutes.
- Restart the phone.
If the phone shows signal but internet still does not work, check the APN.
What to Do If the eSIM Shows No Service
No Service can appear when the phone has not registered on a supported network.
- Confirm that you are already in the covered destination.
- Move outdoors or toward a populated area.
- Turn Airplane Mode on and off.
- Restart the phone.
- Keep automatic network selection enabled.
- Wait for the phone to scan available networks.
- Try manual network selection only after the basic steps.
Remote volcanic areas, ferry routes, mountains and isolated beaches may have weaker coverage than cities and resorts.
What to Do If the Phone Has Signal but No Internet
- Confirm that the eSIM is selected for mobile data.
- Check that Data Roaming is enabled.
- Set the APN to data.esim.
- Save and select the APN profile.
- Turn WiFi off.
- Activate Airplane Mode for 30 seconds.
- Restart the phone.
- Test a new webpage.
Manual Network Selection
Automatic network selection is normally recommended. When the eSIM does not register after the standard steps, manual selection may help.
- Open the travel eSIM settings.
- Find Network Selection or Network Operators.
- Turn off automatic selection.
- Wait for available networks to appear.
- Select a supported network.
- Wait for registration.
Return to automatic selection if the chosen network does not work or when travelling between islands.
Can One Activated eSIM Work Across the Canary Islands?
Yes. When the plan includes the Canary Islands, the same activated eSIM can generally work across supported destinations such as:
- Tenerife.
- Gran Canaria.
- Lanzarote.
- Fuerteventura.
- La Palma.
- La Gomera.
- El Hierro.
You normally do not need to repeat the installation or activation process on each island.
Mobile signal may disappear temporarily during ferry journeys far from the coastline.
Can You Keep Your Primary SIM Active?
Yes. Most dual-SIM phones allow the primary line to remain enabled while the travel eSIM provides mobile data.
This can allow you to:
- Keep your usual telephone number.
- Receive SMS verification codes.
- Receive calls on the main SIM.
- Use WhatsApp with the existing number.
- Use the eSIM for mobile internet.
Your home operator may charge for calls or SMS while roaming. Review its prices before travelling.
Will WhatsApp Keep the Same Number?
Yes. Activating a travel eSIM does not normally change the number registered with WhatsApp.
When prompted to change the WhatsApp number, keep the original one unless you intentionally want to update the account.
WhatsApp messages and calls will use internet from the travel eSIM.
Do Not Delete the eSIM During Activation
Do not delete the eSIM if it does not connect immediately. Some QR codes can only be used once.
Deleting the profile may prevent reinstallation and could require replacement activation details.
Most activation problems are caused by the selected mobile data line, roaming setting, APN or network registration rather than the installation itself.
Can You Activate the Same QR Code on Two Phones?
Usually not. Most travel eSIM QR codes are intended for a single installation on one compatible device.
Do not scan the code on another phone after it has already been installed.
Each traveller or device should normally use a separate eSIM plan.
