My eSIM Is Not Working: Solutions and Common Problems | 2026 Guide

You've installed your NAVEO eSIM, scanned the QR code, waited for activation... but it's not working. No signal, no internet, or something just isn't right. It's frustrating, especially if you're already at the airport or about to start your trip.

Don't worry—95% of eSIM problems can be solved in less than 5 minutes. In this complete guide, we'll solve the most common problems together, step by step, so you can get your connection back as soon as possible.

Before we start, some good news: all NAVEO eSIMs come with a working guarantee. If you're still having problems after following this guide, our team will give you a solution or a full refund.

eSIM Activation Problems

❌ "The QR code won't scan"

Most common causes:

The screen showing the QR code has low brightness
Your phone's camera lens is dirty or out of focus
The QR code has expired (codes are valid for 30 days)
You already used the code on another device

Step-by-step solutions:

Turn screen brightness up to 100% on the screen showing the QR code
Clean your phone's rear camera lens with a soft cloth
Move your phone closer or farther away slowly until it focuses
Find a well-lit place (natural light works better than artificial)
If nothing works, use the "Enter details manually" option:
- On iPhone: Settings > Mobile Data > Add plan > Enter details manually
- On Samsung: Settings > Connections > SIM Manager > Add eSIM > Enter manually
Enter the SM-DP+ Address and Activation Code that came in your NAVEO email

If the code has expired: Contact soporte@naveo.mx with your order number. We'll send you a new QR code in less than 2 hours, at no cost.

❌ "eSIM not compatible" or "This device doesn't support eSIM"

Causes:

Your phone doesn't support eSIM technology
Your device is older than 2018
Your original carrier locked the eSIM feature

How to check compatibility:

Compatible iPhones:

iPhone XS, XS Max, XR and later (2018+)
iPhone SE (2nd and 3rd generation)
All iPhone 11, 12, 13, 14, 15, 16

Compatible Samsung phones:

Galaxy S20, S21, S22, S23, S24 series
Galaxy Note 20 series
Galaxy Z Fold and Z Flip series
Galaxy A54 5G, A55 5G

Compatible Google Pixel phones:

Pixel 3 and later
Pixel 3a and later

If your device is NOT on the list: Unfortunately, your phone doesn't support eSIM. Alternative options:

Order a physical SIM from NAVEO (available for most destinations)
Rent a Pocket WiFi at your destination airport
Use your Mexican carrier's international roaming

❌ "You've reached the maximum number of eSIMs installed"

Cause: Phones have a limit on how many eSIMs they can store:

iPhone: Up to 8 eSIMs installed, 2 active at the same time
Samsung: Up to 5 eSIMs installed, 2 active at the same time
Google Pixel: Up to 5-7 eSIMs installed

Solution:

Delete old eSIMs you no longer use:
- iPhone: Settings > Mobile Data > Select the old eSIM > Delete Mobile Data Plan
- Samsung: Settings > Connections > SIM Manager > Press and hold the old eSIM > Remove
Restart your phone completely
Try scanning the QR code again

Important: Deleting an eSIM does NOT delete your NAVEO plan. It only removes it from your phone. If you have remaining days or data, we can reinstall it later.

Connection Problems

❌ "My eSIM is installed but there's no signal"

Most common causes:

You didn't turn on "Data Roaming" on the eSIM
Airplane mode is on
The eSIM is disabled
You're in an area with no coverage

Solutions in order (try one at a time):

Step 1: Check airplane mode

Turn off airplane mode if it's on
If it's already off, turn it on for 10 seconds and then turn it off again

Step 2: Turn on "Data Roaming" on the eSIM

iPhone: Settings > Mobile Data > Your NAVEO eSIM > Turn on "Data Roaming"
Samsung: Settings > Connections > SIM Manager > Your NAVEO eSIM > Turn on "Data Roaming"
Generic Android: Settings > Mobile Networks > Your eSIM > Turn on "Data Roaming"

This is the #1 mistake travelers make. Without "Data Roaming" turned on, the eSIM will never connect to local networks.

Step 3: Check that the eSIM is active

Make sure the eSIM toggle is in the "On" position
Check that it's the default SIM for mobile data

Step 4: Force a reconnection

Restart your phone completely (power off and on)
Wait 2-3 minutes after turning it on
Check if signal appears

Step 5: Manual network selection If there's still no signal:

iPhone: Settings > Mobile Data > Options > Network Selection > Turn off "Automatic" and manually choose a local network (Vodafone, Orange, Movistar, etc.)
Samsung: Settings > Connections > Mobile Networks > Network Operators > Turn off "Select automatically" and choose an available network

❌ "I have WiFi but mobile data doesn't work"

Cause: Your phone is using WiFi and isn't switching to mobile data when the WiFi fails.

Solutions:

Test 1: Temporarily turn off WiFi

Open the control panel
Turn off WiFi
Check whether pages load over mobile data

Test 2: Check the default SIM for data

iPhone: Settings > Mobile Data > Mobile Data > Select your NAVEO eSIM
Samsung: Settings > Connections > SIM Manager > Preferred SIM > Mobile Data > Select your NAVEO eSIM

Test 3: Turn off "Wi-Fi Assist" or "WiFi+" Some phones have features that keep WiFi active even when it's not working:

iPhone: Settings > Mobile Data > Turn off "Wi-Fi Assist" at the bottom of the page
Samsung: Settings > Connections > WiFi > Advanced > Turn off "Smart network switching"

❌ "The connection is very slow or unstable"

Possible causes:

An area with poor coverage (basements, rural areas)
Network congestion (many users on the same tower)
Incorrect network settings (5G vs 4G)
Apps consuming data in the background

Solutions to improve speed:

1. Change the network mode (from 5G to 4G):

iPhone: Settings > Mobile Data > Options > Voice & Data > Change from "5G Auto" to "LTE" or "4G"
Samsung: Settings > Connections > Mobile Networks > Network Mode > Select "4G/LTE only"

Why does this work? In some areas, the 4G network is less congested than 5G and offers better real-world speeds.

2. Toggle Airplane Mode

Turn on airplane mode for 10 seconds
Turn it off and wait 30 seconds
Your phone will reconnect to the best available tower

3. Close background apps

Check which apps are consuming data
Close streaming apps, automatic updates, and cloud syncing

4. Move to an open area

Get out of basements, subways, or buildings with thick walls
Move closer to windows or step outside

5. Check your actual speed

Use speedtest.net or fast.com to measure your real speed
Share the result with support if it's consistently below 5 Mbps

Data Problems

❌ "My data ran out sooner than expected"

Common causes:

Apps consuming data in the background
Automatic operating system updates
Photo/video syncing to the cloud
High-quality video streaming
Tethering/hotspot with other devices

How to diagnose your data usage:

On iPhone:

Settings > Mobile Data
Scroll down to see usage per app
Identify the apps consuming the most

On Samsung/Android:

Settings > Connections > Data Usage
Review usage per app
Look at the daily usage chart

Apps that consume the most data:

App	Average usage per hour
Netflix/YouTube (HD)	1.5 - 3 GB
Instagram/TikTok	600 MB - 1 GB
Zoom video calls	500 MB - 1 GB
Spotify (high quality)	150 MB
Google Maps (navigation)	50 - 100 MB
WhatsApp (text/photos)	20 - 50 MB

Solutions to control your data usage:

1. Turn off automatic updates:

iPhone: Settings > App Store > Turn off "App Updates" over mobile data
Android: Play Store > Settings > Network Preferences > Update apps over WiFi only

2. Limit streaming quality:

Netflix/YouTube: Set quality to "Data Saver" or "480p"
Spotify: Use "Normal" quality instead of "High"

3. Turn off cloud syncing over mobile data:

iPhone: Settings > Photos > Turn off "iCloud Photos" over mobile data
Android: Google Photos > Settings > Back up > WiFi only

4. Use WiFi whenever it's available:

Hotels, cafés, airports
Save mobile data for when you really need it

5. Buy a data top-up: From mynaveo.com you can add extra GB to your existing plan without buying a new one. The process takes 2 minutes.

❌ "I can't use data even though I have GB available"

Causes:

Incorrect APN (Access Point Name)
Mobile network settings disabled
Data restrictions on your phone

Solution: Check and configure the APN

The APN is the setting that tells your phone how to connect to the data network.

On iPhone: The APN is usually configured automatically. If it doesn't work:

Settings > Mobile Data > Mobile Data Network
If the fields are empty, contact support to get the specific APN details for your destination

On Android/Samsung:

Settings > Connections > Mobile Networks > Access Point Names (APN)
Select the active APN (it should have a blue or green dot)
If it doesn't work, create a new APN:
- Name: NAVEO
- APN: (support will provide it based on your destination)
- Leave all other fields at their defaults
Save and select the new APN
Restart your phone

If you don't know the correct APN: Contact soporte@naveo.mx with your destination and phone model. We'll send you the exact configuration in less than 2 hours.
