Canary Islands eSIM for iPhone: Installation, Setup and Mobile Data Guide

Using an eSIM on your iPhone is one of the easiest ways to get mobile data in the Canary Islands. You can install the plan digitally before departure, keep your usual SIM active and connect after arriving in Tenerife, Gran Canaria, Lanzarote, Fuerteventura or another supported island.

An iPhone travel eSIM is particularly useful for maps, accommodation messages, airport transfers, ferry bookings, restaurant searches and communication through WhatsApp. It removes the need to replace your physical SIM card or search for a mobile shop after landing.

Correct installation is only the first step. After arrival, you must also select the eSIM for mobile data, enable Data Roaming on the travel line and prevent the iPhone from switching unexpectedly to your primary SIM.

Quick answer: Install your Canary Islands eSIM on stable WiFi before travelling. After arrival, turn on the eSIM, select it under Cellular Data, enable Data Roaming and disable Allow Cellular Data Switching. If the connection does not start, check that the APN is set to data.esim.

Does iPhone Support eSIM in the Canary Islands?

Many recent iPhone models support eSIM, but compatibility depends on the exact model, country of purchase and whether the device is carrier-locked.

In general, eSIM support is available on many devices from the following generations:

• iPhone XS and iPhone XS Max.
• iPhone XR.
• iPhone 11 series.
• iPhone SE from supported newer generations.
• iPhone 12 series.
• iPhone 13 series.
• iPhone 14 series.
• iPhone 15 series.
• iPhone 16 series and compatible later models.

Some regional versions may have different SIM capabilities. Always confirm eSIM support directly in the iPhone settings before purchasing a plan.

How to Check Whether Your iPhone Supports eSIM

You can check eSIM compatibility without relying only on the model name.

1. Open Settings.
2. Select Cellular or Mobile Service.
3. Look for Add eSIM or Add Cellular Plan.

If this option is available, the iPhone can normally install an eSIM.

You can also dial:

*#06#

If the device displays an EID in addition to the IMEI, this usually indicates eSIM capability.

Check Whether the iPhone Is Carrier-Locked

An eSIM-compatible iPhone may still reject a travel plan when it is locked to a specific mobile operator.

To check:

1. Open Settings.
2. Select General.
3. Select About.
4. Find Carrier Lock or Network Provider Lock.

If the phone shows No SIM restrictions, it is generally unlocked. If a restriction appears, contact the original operator before travelling.

Why Use an eSIM on iPhone in the Canary Islands?

An eSIM provides several practical advantages for iPhone users travelling to the Canary Islands.

• Install mobile data before departure.
• Keep the primary SIM inside the phone.
• Continue receiving calls or SMS on the usual number.
• Use WhatsApp with the existing account.
• Avoid searching for a local SIM shop.
• Connect during airport transfers.
• Use the same plan across included Canary Islands.
• Switch mobile data lines through iPhone settings.

A travel eSIM is normally data-only, so it does not usually provide a new local telephone number.

When Should You Install the eSIM?

Install the eSIM before travelling while connected to stable private WiFi. This gives you time to complete the setup and resolve any installation issue before departure.

Before installing, check the activation conditions of the selected plan. Some plans begin when they first connect to a supported network, while others may begin immediately after installation.

Do not activate the travel line too early if the validity period begins before arrival.

How to Install a Canary Islands eSIM on iPhone with a QR Code

1. Connect the iPhone to stable WiFi.
2. Open Settings.
3. Select Cellular or Mobile Service.
4. Select Add eSIM.
5. Choose Use QR Code.
6. Scan the QR code provided after purchase.
7. Follow the installation prompts.
8. Label the plan as NoveSIM, Travel or Canary Islands.
9. Keep the line installed until the trip is complete.

The QR code should ideally be displayed on another device or printed. If it is stored on the same iPhone, use any supported image-based installation option shown by the device.

How to Install the eSIM Manually

If QR installation is not possible and manual details are provided, you may be able to enter them directly.

1. Open Settings.
2. Select Cellular or Mobile Service.
3. Select Add eSIM.
4. Choose Use QR Code.
5. Select Enter Details Manually.
6. Enter the SM-DP+ address.
7. Enter the activation code.
8. Complete the setup prompts.

Enter the details exactly as provided. Avoid adding spaces or changing capitalisation unless instructed.

Recommended iPhone Settings After Installation

iPhone Setting	Recommended Configuration
Travel eSIM line	Enabled after arrival
Cellular Data	Select NoveSIM or Travel
Data Roaming on travel eSIM	Enabled
Allow Cellular Data Switching	Disabled
Primary SIM Data Roaming	Disabled unless intentionally used
APN	data.esim

How to Select the eSIM for Cellular Data

Installing the eSIM does not always make it the active data line automatically.

1. Open Settings.
2. Select Cellular or Mobile Service.
3. Select Cellular Data.
4. Choose the line labelled NoveSIM, Travel or Canary Islands.

Your iPhone should now use the travel eSIM for mobile internet.

How to Enable Data Roaming on the eSIM

Travel eSIM plans normally need Data Roaming enabled because they connect through supported partner networks.

1. Open Settings.
2. Select Cellular or Mobile Service.
3. Select the travel eSIM.
4. Open Cellular Data Options.
5. Enable Data Roaming.

Enable roaming only on the travel eSIM. Keep it disabled on the primary line unless you intentionally want to use your home operator abroad.

Disable Allow Cellular Data Switching

When this setting is enabled, the iPhone may temporarily use mobile data from another SIM if it believes the selected line has a weaker connection.

To avoid unexpected roaming charges:

1. Open Settings.
2. Select Cellular or Mobile Service.
3. Select Cellular Data.
4. Turn off Allow Cellular Data Switching.

This keeps mobile internet assigned to the travel eSIM.

How to Check the APN on iPhone

If the eSIM is installed but mobile internet does not work, check the APN settings.

1. Open Settings.
2. Select Cellular or Mobile Service.
3. Select the travel eSIM.
4. Select Cellular Data Network when available.
5. Enter data.esim in the APN field under Cellular Data.

Field	Value
APN	data.esim
Username	Leave blank
Password	Leave blank

The Cellular Data Network menu may not appear on every iPhone or operator profile. When it is hidden, the APN may be configured automatically.

Can You Keep Your Main SIM Active?

Yes. Dual-SIM functionality allows many iPhones to keep the primary SIM active while the travel eSIM handles mobile data.

This setup may allow you to:

• Keep your usual telephone number.
• Receive SMS verification codes.
• Receive calls on your primary line.
• Continue using WhatsApp with the same number.
• Use NoveSIM only for mobile data.

Incoming calls and SMS may still generate roaming charges depending on your home operator. Review its roaming terms before departure.

Will WhatsApp Keep the Same Number?

Yes. Installing a travel eSIM does not normally change the number linked to WhatsApp.

When WhatsApp asks whether you want to change the registered number, keep the existing number unless you intentionally want to update the account.

Messages and calls through WhatsApp will use internet from the travel eSIM.

Canary Islands eSIM Coverage on iPhone

A compatible plan can generally work across the Canary Islands included in its coverage. This may include popular destinations such as:

• Tenerife.
• Gran Canaria.
• Lanzarote.
• Fuerteventura.
• La Palma.
• La Gomera.
• El Hierro.

Signal strength depends on the local partner network, terrain and exact location. Coverage is usually stronger around cities, resorts, airports and main roads than in remote volcanic landscapes, ravines or isolated beaches.

Can One iPhone eSIM Work During Island Hopping?

Yes. When the selected plan includes the full Canary Islands, the same eSIM can generally remain installed while you travel by ferry or domestic flight.

You should not need to install a new plan each time you change islands. The original data allowance and validity period continue to apply.

Signal may disappear temporarily while a ferry is far offshore because mobile networks mainly cover land and coastal areas.

How Much Data Do iPhone Users Need?

Trip Length	Suggested Data	Typical Usage
Weekend	1GB–3GB	Maps, messages and basic browsing
One week	3GB–5GB	Daily navigation, social media and bookings
Two weeks	5GB–10GB	Regular mobile use and media uploads
One month	10GB–20GB	Daily travel use and occasional calls
Remote work	20GB or more	Hotspot, meetings and cloud applications

iCloud Photos, automatic app updates, video streaming and hotspot use can consume data quickly.

How to Reduce Data Usage on iPhone

• Enable Low Data Mode for the travel eSIM.
• Disable automatic App Store downloads.
• Pause iCloud photo synchronization.
• Download offline maps through WiFi.
• Use accommodation WiFi for streaming.
• Disable background refresh for unnecessary apps.
• Reduce video quality in social media applications.
• Download music and entertainment before travelling.
• Monitor usage in Cellular settings.

How to Enable Low Data Mode

1. Open Settings.
2. Select Cellular or Mobile Service.
3. Select the travel eSIM.
4. Select Cellular Data Options.
5. Open Data Mode.
6. Select Low Data Mode.

This can reduce automatic updates and background network activity.

Can You Use Personal Hotspot with the eSIM?

Many iPhones can share an eSIM connection through Personal Hotspot, provided tethering is supported by the selected plan.

To enable it:

1. Confirm the travel eSIM is selected for Cellular Data.
2. Open Settings.
3. Select Personal Hotspot.
4. Enable Allow Others to Join.

If Personal Hotspot does not appear, check the APN and restart the iPhone. Laptop updates, cloud synchronization and video meetings can use mobile data quickly.

What to Do If the eSIM Is Installed but Shows No Service

1. Confirm that you are already in the Canary Islands.
2. Open Cellular settings and enable the travel eSIM.
3. Select it under Cellular Data.
4. Enable Data Roaming on the travel line.
5. Disable Allow Cellular Data Switching.
6. Turn Airplane Mode on for approximately 30 seconds.
7. Turn Airplane Mode off and wait for network registration.
8. Restart the iPhone.
9. Move to an outdoor or more populated area.

Network registration may take a few minutes after arrival.

What to Do If the iPhone Has Signal but No Internet

If the iPhone displays signal bars but webpages and applications do not load:

1. Confirm that the travel eSIM is selected for Cellular Data.
2. Check that Data Roaming is enabled.
3. Confirm the APN is data.esim.
4. Disable WiFi temporarily to test mobile data.
5. Activate Airplane Mode for 30 seconds.
6. Restart the phone.
7. Try opening a new webpage.

A visible network name does not always mean that the mobile data settings are correct.

What to Do If the eSIM Is Slow

Mobile speed can vary depending on location, network congestion, terrain and plan conditions.

• Move outdoors or closer to a populated area.
• Turn Airplane Mode on and off.
• Restart the iPhone.
• Check whether a daily high-speed allowance has been reached.
• Pause background downloads.
• Disable hotspot devices that are not needed.
• Try the connection again later.

Remote beaches, mountains, volcanic parks and ferry routes may have weaker or less consistent service.

Do Not Delete the eSIM While Troubleshooting

Do not remove the eSIM unless support specifically instructs you to do so. Some QR codes can only be used for one installation.

Deleting the plan may prevent you from installing it again without replacement details.

Most connection problems can be resolved by checking the selected data line, roaming setting, APN and network registration.

Can You Install the Same eSIM on Two iPhones?

Usually not. Most travel eSIM profiles are intended for one compatible device and one installation.

Do not scan the QR code on another phone after installation. Each traveller or device should use its own plan unless the selected product explicitly states otherwise.

Can You Transfer the eSIM to a New iPhone?

Travel eSIM transfer is not always supported. Apple’s built-in eSIM transfer feature may work for some domestic operator plans but not necessarily for temporary travel profiles.

Install the plan on the iPhone you intend to carry during the trip. Contact support before replacing, resetting or changing the device.

Should You Turn Off the Primary SIM?

You do not normally need to turn it off completely. Keeping it active can be useful for calls and SMS.

To avoid accidental roaming charges:

• Select the travel eSIM for Cellular Data.
• Disable Data Roaming on the primary SIM.
• Disable Allow Cellular Data Switching.
• Avoid answering chargeable calls unless necessary.
• Review your home operator’s roaming prices.
