If your Mexico eSIM is installed but mobile data is not working, the APN settings may need to be checked manually.
Most travel eSIMs configure automatically after installation, but sometimes your phone may not load the correct APN. This can cause no internet, slow data, or a connection that shows signal but does not load websites or apps.
Quick answer: For most Mexico travel eSIMs, the APN should be set to data.esim. After entering the APN, make sure your eSIM is selected for mobile data and data roaming is enabled on the eSIM line.
Top Mexico eSIMs
Mexico eSIM APN Settings
| Setting | Value |
|---|---|
| APN | data.esim |
| Username | Leave blank |
| Password | Leave blank |
In most cases, you only need to enter the APN value. Leave all other fields blank unless your provider gives different instructions.
When Do You Need to Enter APN Settings?
You may need to check or enter APN settings if:
- Your eSIM is installed but has no internet
- Your phone shows signal but apps do not load
- Mobile data is slow or unstable
- The eSIM connects but websites do not open
- You recently reset network settings
- You changed network selection manually
If everything works automatically, you do not need to change APN settings.
Before Changing APN Settings
Before editing APN, check these basics first:
- Your eSIM is installed
- Your eSIM line is turned on
- Your eSIM is selected for mobile data
- Data roaming is enabled on the eSIM
- Your plan includes Mexico coverage
- Your phone is unlocked and eSIM-compatible
If one of these settings is incorrect, mobile data may not work even with the correct APN.

- Tap Cellular Data Network.
- Enter data.esim in the APN field.

How to Set APN on Android
Android menus vary by brand, but the process is usually similar.
- Open Settings.

- Enter data.esim in the APN field.

Important: Enable Data Roaming
Most travel eSIMs require data roaming to be turned on.
This does not mean you are using expensive roaming from your home carrier. It simply allows the travel eSIM to connect to the local partner network in Mexico.
Recommended roaming setup:
- Data roaming ON for your Mexico eSIM
- Mobile data set to your Mexico eSIM
- Automatic data switching OFF
- Primary SIM data roaming OFF unless needed
Recommended Mexico eSIM Settings
| Setting | Recommended Option |
|---|---|
| Mobile Data | Select your Mexico eSIM |
| Data Roaming | ON for eSIM |
| APN | data.esim |
| Username | Blank |
| Password | Blank |
| Automatic Data Switching | OFF |
What If the APN Menu Is Missing?
Some phones do not allow manual APN editing for certain eSIM profiles.
If the APN menu is missing:
- Restart your phone
- Make sure the eSIM is enabled
- Set the eSIM as mobile data line
- Turn data roaming ON
- Try airplane mode for 30 seconds
- Check whether data starts working automatically
If APN is managed automatically, you may not need to enter it manually.
What If the eSIM Shows Signal but No Internet?
If your eSIM shows signal bars but mobile data does not work, check:
- Is the eSIM selected for mobile data?
- Is data roaming enabled?
- Is the APN set to data.esim?
- Is automatic data switching disabled?
- Has the phone been restarted?
Signal bars only show network connection. They do not always mean mobile data is correctly configured.
What If APN Is Correct but Internet Still Does Not Work?
If APN is correct and there is still no internet, try the following:
- Turn airplane mode ON.
- Wait 30 seconds.
- Turn airplane mode OFF.
- Restart your phone.
- Try manual network selection.
- Move to an area with stronger signal.
- Check your data balance and plan validity.
Sometimes the phone needs to reconnect to the local network after APN changes.
Manual Network Selection in Mexico
If your phone does not connect automatically, try selecting a network manually.
| Network | Typical Use |
|---|---|
| Telcel | Strong nationwide coverage |
| AT&T Mexico | Good in cities and tourist zones |
| Movistar | Useful in some urban areas |
Select one available network, wait one or two minutes, then test mobile data. If it does not work, try another available network.
