Planning a trip to Spain?
One of the first things you will need after landing is reliable mobile data.
You need internet for Google Maps, airport directions, hotel bookings, ride-hailing apps, WhatsApp, restaurant searches, translation apps, and keeping in touch with family and friends.
Instead of waiting at an airport shop to buy a physical SIM card, you can use an eSIM for Spain.
A travel eSIM can be purchased before your trip and activated on a compatible phone, allowing you to connect to mobile data as soon as you arrive.
In this guide, we will explain what a Spain eSIM is, where to buy one, what to check before purchasing, and how Nexar can help you stay connected during your trip.
What Is an eSIM for Spain?
An eSIM is a digital SIM that is built into your compatible smartphone.
Unlike a traditional SIM card, you do not need to physically insert anything into your phone.
A Spain eSIM provides mobile data through a supported network while you are travelling in Spain.
This can be especially useful for international travelers because you can keep your normal SIM card in your phone while using the eSIM for mobile data.
Nexar’s travel eSIM service is designed for data connectivity and allows travelers to keep their main SIM active while using the eSIM for internet access. (Nexar)
Why Use a Spain eSIM Instead of a Physical SIM?
There are several advantages.
No Airport SIM Shopping
You can purchase your eSIM before leaving home.
That means you do not have to find a mobile shop immediately after landing.
No Physical SIM Card
There is nothing to remove from your phone and nothing small to lose.
Keep Your Main Number
You can keep your regular Nigerian SIM in the phone while using the eSIM for data, depending on your device and settings.
Nexar specifically notes that its eSIM can be used for data while your regular SIM remains active for calls and SMS. (Nexar)
Easy Activation
A compatible eSIM can be installed digitally, usually through a QR code or activation instructions.
Useful for Travel
Your internet connection can be ready when you need maps, messaging, translation, and other travel apps.
Where Can You Buy an eSIM for Spain?
You have several choices when looking for a Spanish eSIM.
You can purchase a travel eSIM from an international eSIM provider before your trip.
For Nigerians travelling to Spain, Nexar is one option to consider because it provides travel eSIM plans covering multiple countries.
Nexar’s eSIM platform allows you to select your destination, purchase a plan, receive the eSIM, and activate it by scanning the provided QR code. You can check the available options through Nexar eSIM.

- Coverage
- Activation requirements
Choose a plan based on how long you expect to stay and how much data you normally use.
Step 4: Purchase the eSIM
Complete the payment process.
Nexar says the eSIM is sent after payment, allowing you to proceed with installation and activation. (Nexar)
Step 5: Install the eSIM
Follow the instructions provided with your eSIM.
Depending on your phone, this may involve scanning a QR code through the mobile or cellular settings.

Spain eSIM for Travelers: What Does It Cover?
A Spain eSIM is particularly useful for mobile data.
You can use your data connection for:
- Google Maps
- Uber or other transport apps
- Hotel bookings
- Google Search
- Social media
- Video calls
- Translation apps
- Online banking
- Travel information
Nexar’s eSIM service is data-only, meaning the eSIM itself does not provide traditional phone calls or SMS. However, internet-based services such as WhatsApp, FaceTime and Skype can work over the data connection. (Nexar)
Can You Use WhatsApp With a Spanish eSIM?
Yes.
If your WhatsApp account is already registered to your normal phone number, you can generally continue using WhatsApp over the eSIM’s mobile data connection.
Your WhatsApp account does not automatically change simply because you are using a different data connection.
This is useful for travelers who want to stay in contact with family and friends without paying traditional roaming charges.
Can You Keep Your Nigerian SIM While Using a Spain eSIM?
On compatible dual-SIM devices, yes.
You can keep your Nigerian physical SIM in the phone while using the Spain eSIM for data.
This means you can maintain access to your regular number while using the travel eSIM for internet connectivity.
However, be careful with your Nigerian SIM’s roaming settings. If you do not want roaming charges, make sure your phone is configured to use the Spain eSIM for mobile data.
Nexar also highlights the ability to keep your main SIM active while using its eSIM for data. (Nexar)
Is Your Phone Compatible With eSIM?
Before buying a Spain eSIM, check whether your phone supports eSIM technology.
Many recent smartphones do, but compatibility depends on the specific model and sometimes the region where the device was purchased.
Nexar lists examples including:
- iPhone XS and newer
- Samsung Galaxy S20 and newer
- Google Pixel 3 and newer
You should still check your exact phone model before purchasing. (Nexar)
How Much Data Do You Need for Spain?
This depends on how you use your phone.
Light User
If you mainly use WhatsApp, maps, email, and occasional browsing, a smaller data plan may be enough.
Moderate User
If you regularly use social media, maps, music streaming, and video calls, choose a larger allowance.
Heavy User
If you stream lots of video, upload content, use your phone as a hotspot, or work online while travelling, you will need considerably more data.
A good approach is to look at your current mobile-data usage and use that as a starting point.

Spain eSIM vs Roaming
International roaming can be convenient because you do not have to change anything.
However, roaming costs can vary considerably depending on your Nigerian mobile provider and plan.
A travel eSIM gives you another option.
Instead of relying entirely on your home network’s roaming service, you can purchase a dedicated travel data plan for Spain.
Nexar positions its eSIMs as a way to avoid expensive roaming charges and connect to mobile data without purchasing a physical SIM at your destination. (Nexar)
Things to Check Before Buying a Spanish eSIM
Before paying, check these five things.
1. Phone Compatibility
Make sure your phone supports eSIM.
2. Coverage
Check that the plan covers Spain and the locations you intend to visit.
3. Data Allowance
Choose enough data for your expected usage.
4. Validity
Check how many days the plan remains active.
5. Activation Rules
Some eSIMs begin their validity when installed, while others start when they connect to a supported network.
Read the specific plan instructions before installation.
Tips for Using a Spain eSIM
Install Before You Travel
If possible, install the eSIM while you still have reliable internet access.
Label Your SIMs
If your phone supports multiple lines, label them clearly, such as:
Nigeria SIM
and
Spain eSIM
This makes it easier to select the correct line.
Set the Spain eSIM as Your Data Line
When you arrive, select the travel eSIM for mobile data.
Turn Off Data Roaming on Your Main SIM
If you want to avoid unexpected roaming charges, check the data-roaming settings for your Nigerian SIM.

Even with an eSIM, having offline maps is useful in case you temporarily lose signal.
