Why Your eSIM Shows ‘SOS Only’ or ‘No Service’
Before diving into the fixes, let’s quickly understand the common culprits. This error usually isn’t a sign of a faulty eSIM. Instead, it often points to a simple configuration issue. The most frequent causes include:
- Incorrect Settings: Data Roaming might be turned off, which is essential for a travel eSIM to connect to partner networks.
- Activation Glitches: The eSIM might not have been fully activated or selected as the primary data source on your device.
- Network Issues: Your phone may not have automatically connected to a supported local network provider.
- APN Configuration: The Access Point Name (APN), which allows your phone to connect to the internet, may need to be set manually.
5 Quick Fixes for Your eSIM Connectivity Issues
Work through these steps in order. Most of the time, one of the first three will solve your problem!
1. Enable Data Roaming on Your eSIM
This is the most common reason for an eSIM not working abroad. Your primary SIM’s data roaming should be OFF to avoid expensive charges, but your travel eSIM’s data roaming must be ON.
On an iPhone:
- Go to Settings > Cellular.
- Select your Yoho Mobile eSIM under ‘Cellular Plans’.
- Ensure the toggle for Data Roaming is turned ON.
On an Android:
- Go to Settings > Network & internet > SIMs.
- Select your Yoho Mobile eSIM.
- Find the Roaming option and make sure it’s enabled.
2. Check and Set Your APN Manually
The Access Point Name (APN) is the gateway between your device and the mobile network’s internet. While Yoho Mobile eSIMs usually configure this automatically, sometimes a manual check is needed.
After installing your eSIM, you should receive the APN details. Check your phone’s settings to ensure they match. You can typically find this under Cellular Data Network (iOS) or Access Point Names (Android) in your eSIM settings. If the fields are empty, enter the details provided in your installation instructions. According to the GSMA, the organization behind eSIM standards, proper configuration is key to seamless global roaming.
3. Manually Select a Supported Network Operator
Sometimes, your phone doesn’t automatically connect to the best local network. Manually selecting one can force the connection.
- Navigate to your phone’s mobile network settings (usually under Cellular > Network Selection on iOS or Network & internet > SIMs > Mobile networks on Android).
- Turn off Automatic network selection.
- Your phone will scan for available networks. Wait for the list to appear and select one of the supported operators listed in your Yoho Mobile eSIM’s welcome information.
This process is similar to what experts at tech outlets like The Verge often recommend for troubleshooting general connectivity.
4. Restart Your Device
The oldest trick in the tech book often works wonders. A simple restart can resolve temporary glitches and force your phone to re-establish a fresh connection with the local network. Turn your phone completely off, wait about 30 seconds, and then turn it back on. This simple action can often resolve the ‘eSIM connected but no internet access abroad’ issue.
5. Verify Your eSIM is Properly Installed and Active
Finally, double-check that your eSIM is active and set as the line for cellular data.
- Ensure the eSIM is turned on: In your cellular settings, make sure the toggle for ‘Turn On This Line’ is active for your Yoho Mobile eSIM.
- Select the eSIM for Cellular Data: In the same settings menu, ensure that ‘Cellular Data’ is set to your Yoho Mobile eSIM, not your primary line.
Remember, for iOS users, installing a Yoho Mobile eSIM is incredibly simple. After purchase, just tap the ‘Install’ button in our app or email—no need to scan a QR code. Your iPhone will handle the rest in under a minute! For Android users, the standard QR code or manual activation process applies. You can find more details on Apple’s official eSIM support page.
Frequently Asked Questions (FAQ)
What should I do if my eSIM shows SOS only right after I land in Japan?
First, enable Data Roaming for your eSIM in your phone’s cellular settings. If that doesn’t work, try manually selecting a network operator like Docomo or SoftBank from the available networks list. A quick restart of your phone can also resolve this common issue. If you’re still stuck, you can browse our affordable eSIM plans for Japan and be sure your phone is on our eSIM compatible devices list.
Why is my travel eSIM connected but I have no internet access?
This classic problem, ‘eSIM connected no internet’, is almost always caused by incorrect APN (Access Point Name) settings or data roaming being turned off. First, confirm data roaming is enabled for your travel eSIM. If it is, check that the APN settings in your device match those provided in your eSIM installation guide.
Can I fix my eSIM’s ‘No Service’ issue on my iPhone myself?
Absolutely. Most ‘No Service’ issues on iPhones are solvable without technical support. Follow the steps in this guide: 1) Enable Data Roaming, 2) Manually select a network, 3) Restart your device, and 4) Verify the eSIM is turned on and selected for cellular data. These steps resolve over 90% of connectivity problems.
Does my phone need to be unlocked for a travel eSIM from Yoho Mobile to work?
Yes, your device must be carrier-unlocked to use a third-party eSIM. A locked phone will not accept an eSIM from another provider, which can lead to a ‘No Service’ error. You can check if your phone is unlocked by contacting your home carrier before you travel.
