Ensure Your Phone is Unlocked

Your phone must be unlocked for the eSIM to function with a new carrier. If your phone is locked to your home carrier, it will prevent any other network, including the one your eSIM is trying to connect to, from recognizing it.

How to Check: Go to your phone’s settings. Look for “Network & Internet,” “Cellular,” or “Mobile Data.” Within these menus, you should find an option related to “Network Provider” or “Carrier.” If it automatically searches and displays available networks, your phone is likely unlocked. If it shows an error message or only lists your home carrier with no other options, it might be locked.
Action if Locked: Contact your original mobile carrier to request an unlock. They typically have specific procedures and eligibility requirements. Be prepared to provide your account details and IMEI number.

Verify Your eSIM Profile is Correctly Installed

An improperly installed eSIM is like a key inserted into the wrong lock; it simply won’t work. Double-check that the installation process was completed successfully.

How to Check:
iPhone: Go to Settings > Cellular > Cellular Plans. You should see your eSIM listed here. If it’s listed with a label you don’t recognize or looks incomplete, it might be an issue.
Android: Go to Settings > Network & Internet > SIMs (or Mobile Network). Your eSIM should appear as an available option here.
Action if Incomplete: Most eSIM providers offer the option to re-download or re-install the eSIM profile. You may need to initiate this through their app or website. Follow their instructions precisely.

Confirm Data Roaming is Enabled

Even with a functional eSIM, if data roaming is switched off, you won’t be able to access the internet outside your home network’s coverage. This is a common pitfall.

How to Check:
iPhone: Go to Settings > Cellular > Cellular Data Options. Ensure “Data Roaming” is toggled ON.
Android: Go to Settings > Network & Internet > SIMs (or Mobile Network). Tap on your eSIM profile and toggle “Data Roaming” ON.
Important Note: Be aware of your home carrier’s international roaming charges if you’re using a physical SIM alongside your eSIM. This guide focuses on eSIM functionality.

Network Selection: Finding the Right Path

Sometimes, your phone might struggle to automatically connect to the correct network. Manually selecting a network can be the key to unlocking your signal. Think of this as manually tuning your radio to find a clear station.

Understanding Network Operators

Your eSIM is designed to connect to specific network operators in the country you’re visiting. These operators have agreements with your eSIM provider. If your phone is trying to connect to an unsupported operator, you’ll remain without service.

How to Find Compatible Operators:
eSIM Provider’s Website/App: This is your primary resource. Most eSIM providers will list the supported network operators for each country they cover.
Travel Itinerary: If you booked a package or have documentation, check for any mention of recommended networks.
Troubleshooting Tip: If you have multiple eSIMs installed, ensure you have selected the correct one for your current destination.

Manual Network Selection Process

This is where you take direct control of your phone’s connection. It requires a bit more patience but can be highly effective.

How to Perform Manual Network Selection:
iPhone: Go to Settings > Cellular > Cellular Data Options > Network Selection. Toggle “Automatic” OFF. Your phone will then scan for available networks. Select one from the list that you’ve identified as compatible with your eSIM (refer to your provider’s information). If the first choice doesn’t work, try another compatible one.
Android: Go to Settings > Network & Internet > SIMs (or Mobile Network). Tap on your eSIM profile and then select “Network Operators.” Toggle “Select automatically” OFF. Your phone will scan for available networks. Choose a compatible network from the list. Again, if one doesn’t work, try another.
When to Revert to Automatic: After successfully connecting, set the network selection back to “Automatic” to ensure your phone can switch networks seamlessly if needed.

APN Settings: The Gateway to Data

APN (Access Point Name) settings are crucial for your phone to connect to the internet via the cellular network. They are like the street address and postal code that the data packets need to find their way.

What Are APN Settings?

APN settings tell your phone which gateway to use to access the internet and other data services. They contain information like the APN name, proxy, port, username, and password, depending on the provider.

Why They Matter for eSIMs: While many eSIMs configure these settings automatically, sometimes manual adjustments are necessary, especially if you encounter issues after initial setup or a network change.

How to Find and Configure APN Settings

Your eSIM provider is the ultimate source of truth for correct APN settings.

Where to Find APN Details:
eSIM Provider’s Website/App: Look for a “Help,” “FAQ,” or “Troubleshooting” section. They will usually have a list of APN settings for various countries or a general APN to use.
Confirmation Email: Sometimes, APN details are included in the email you receive after purchasing or installing your eSIM.
How to Manually Set APN:
iPhone: Go to Settings > Cellular > Cellular Data. Tap on “Cellular Data Network.” You will find fields for APN, Username, and Password. Enter the details provided by your eSIM provider. If you encounter issues, you might need to reset network settings (Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings). Note: This will erase all Wi-Fi passwords and Bluetooth pairings.
Android: Go to Settings > Network & Internet > SIMs (or Mobile Network). Tap on your eSIM profile, then navigate to “Access Point Names” (or APNs). You can then either edit an existing APN entry or create a new one by tapping the “+” icon or the three-dot menu. Fill in the details provided by your eSIM provider accurately.
Troubleshooting Tip: If you create a new APN, make sure to select it from the list of APNs after saving.

Connectivity Issues Beyond the Basics

If the standard checks and network selections don’t resolve your “No Signal” problem, it’s time to explore some less common, but still relevant, troubleshooting avenues.

Check for Network Outages or Maintenance

Even the best networks can experience temporary disruptions. Your eSIM provider relies on local network infrastructure, so an outage in that region will affect everyone.

How to Check for Outages:
eSIM Provider’s Status Page: Many providers have a web page or an app section that reports on network status and any known issues in specific countries.
Local News/Social Media: Sometimes, for larger outages, local news outlets or social media channels will report on disruptions.
Hotel Wi-Fi/Public Wi-Fi: If you can access Wi-Fi, try searching for “[Country Name] mobile network outage” or checking your eSIM provider’s social media feeds.

Ensure Your Device’s Software is Up to Date

Outdated software can sometimes cause compatibility problems with newer network technologies or eSIM profiles.

Why Updates Matter: Software updates often include fixes for connectivity bugs and improved support for cellular modems.
How to Update Your Device:
iPhone: Go to Settings > General > Software Update.
Android: Go to Settings > System > System Update (the exact path may vary depending on your Android version and manufacturer).
Prerequisites: Ensure you have a stable Wi-Fi connection and sufficient battery life before starting an update.

Reset Network Settings

This is a more drastic step that can resolve persistent network connectivity issues by clearing all saved network configurations on your device.

What it Does: Resetting network settings will delete all saved Wi-Fi networks and passwords, Bluetooth pairings, VPN configurations, and cellular settings. It essentially reverts your device’s network management to its factory default.
How to Reset Network Settings:
iPhone: Go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings.
Android: Go to Settings > System > Reset options > Reset Wi-Fi, mobile & Bluetooth (this wording may vary).
Post-Reset Actions: After resetting, you will need to re-enter Wi-Fi passwords and re-pair Bluetooth devices. You will also need to re-install your eSIM by following the initial setup process.
