If your eSIM is not working in Spain, the problem is usually easy to fix.
Many travelers arrive in Spain and notice one of these issues:
- signal but no internet
- slow connection
- no network available
- eSIM installed but not connecting
In most cases, the issue is caused by one of the following:
- wrong network selected
- data roaming turned off
- wrong SIM chosen for mobile data
- APN or device compatibility issues
This guide explains the most common reasons why an eSIM may not work in Spain and how to fix the problem step by step.
Quick answer: why is my eSIM not working in Spain?
Most eSIM problems in Spain are caused by phone settings, not by the eSIM itself.
The most common fixes are:
- turning data roaming on
- manually switching to another Spanish network
- making sure the eSIM is selected as the active data line
- restarting the phone or toggling airplane mode
1. Wrong network is selected
Spain has several major mobile operators, and your phone may automatically connect to a weaker or less suitable network.
Main mobile networks in Spain include:
- Movistar
- Vodafone Spain
- Orange Spain
- Yoigo
If your eSIM shows signal but internet is slow or unavailable, this is often the first thing to check.
How to fix it:
- open Network Selection
- turn off automatic network selection
- choose another network manually
- test the connection again
In many cases, switching networks solves the issue immediately.
2. Data roaming is turned off
Most travel eSIM plans require data roaming to be turned on when you are abroad.
If data roaming is disabled, your phone may detect the network but fail to connect to mobile internet.
Fix: Settings → Mobile Data → eSIM → Data Roaming → ON

3. The eSIM is installed but not active yet
If you installed your eSIM before traveling, it may activate only after it detects a supported Spanish network.
This is completely normal for many travel eSIM plans.
If you just landed and it is not working instantly, wait a moment, restart your device, or switch the network manually.

4. The wrong SIM is selected for mobile data
Your phone may still be using your primary SIM card for mobile data instead of the travel eSIM.
This is one of the most common setup mistakes.
Check this setting: Settings → Mobile Data → Data Line → select your eSIM

5. Device compatibility limitations
Some phones support eSIM, but that does not always mean they work perfectly with every travel setup.
Problems are more common with:
- older phones
- imported devices
- region-locked models
- phones with incomplete band support
In rare cases, the phone supports eSIM but has network compatibility limitations in Spain.

6. APN settings did not load correctly
This is less common, but it can happen.
Typical symptoms:
- signal bars are visible
- mobile internet does not work
- apps do not load even though the eSIM appears active
Try these steps:
- restart the phone
- toggle airplane mode on and off
- reinstall the eSIM profile if necessary
- ask support for APN settings if the issue continues
7. Your data plan expired or ran out
Your phone may still show signal even if your data allowance has been used up or the validity period has ended.
Check whether you received notifications such as:
- activation confirmation
- 50% usage alert
- 80% usage alert
- data exhausted warning
- expiry reminder

Spain-specific tip: try Movistar first
In Spain, connection quality can vary depending on the network your phone chooses automatically.
- Movistar often provides the strongest nationwide coverage
- Vodafone Spain performs well in many urban areas
- Orange Spain offers balanced coverage
- Yoigo may be weaker in some rural areas
If your internet is unstable, manually switching from one network to another can make a major difference.

- turn on data roaming

When should you contact support?

These cases are less common and may require reprovisioning or a profile reset.
Biggest misconception
Myth: eSIM does not work in Spain.
Reality: eSIM works in Spain very well. Most issues are caused by settings, network choice, or data line configuration.
Real traveler example
A traveler lands in Barcelona and sees signal, but internet is slow or unstable.
The phone automatically connected to Yoigo. After manually switching to Movistar, the connection improves immediately.
This is one of the most common real-world eSIM issues in Spain.

- wrong network selection
- data roaming turned off

- compatibility or APN issues
The good news is that most of these problems can be fixed in just a few minutes through your phone settings.
