Sometimes, your eSIM on an iOS device might take a bit longer to start working. This issue usually occurs when you have set up an eSIM but haven’t reached your destination country/region.

The good news is, even if your phone says “activating” or “activation failure,” the eSIM is actually ready and installed. The acivation process will finish when you arrive at your destination with network coverage.

Even if the eSIM seems stuck on “activating,” you should use other phone features that don’t need a network connection.

When you reach your destination and get network coverage, the eSIM will start working, and you can use it without any problems.

If your eSIM supports multiple networks, you can try to select a different network than your current one, to see if it offers a better service.

Slow internet speed can result from various different factors, such as network congestion, signal interference, and technical problems with either your device or the network.

Consider following the following steps to solve slow internet speed on your eSIM:

1. Check the supported network type for your specific country (2G, 3G, 4G, or 5G) and make sure it matches your device’s network type.

2. Check your device’s signal strength indicator to ensure you have a strong signal. Slow internet connection can result from a weak signal. If your signal is weak, consider moving nearer to the router or switching to another network.

3. Restart your device. Turn off your device, wait a few seconds, and then turn it back on.

4. Check for software updates. Software updates can solve bugs and enhance performance, including internet speed.

5. Reset your network settings. Resetting network settings can help address configuration issues that may be causing slow internet speed. Go to Settings > System > Reset Options > Reset Wi-Fi, Mobile & Bluetooth to reset your network settings.

How To Fix "This Code is No Longer Valid" Error

Buying a travel eSIM when traveling abroad is a smart way to avoid unexpected roaming fees for data. Most travel eSIMs are pre-paid, one-time use cellular data eSIMs without a phone number. It is recommended to install the eSIM while connected to Wi-Fi and activate it once you arrive at your destination.

In this post, we will discuss the most likely reasons for this error and how to fix it.

"This Code is No Longer Valid" Error

The "eSIM Cannot Be Added - This code is no longer valid" error is a common issue encountered when adding a new travel eSIM. For iPhones running iOS 15 or earlier versions, the error message might appear as "Cellular Plan Cannot Be Added".

Why This Troubleshooting Message Appears

• The eSIM code has been used before: This error usually means that the QR code you are scanning has already been used. eSIM QR codes typically contain activation information and can usually only be used once for security reasons. If you have installed and deleted the eSIM before, trying to use the same QR code again will result in this error. Therefore, do not delete the eSIM unless you are certain you no longer need it.
• Poor connection during installation: A stable internet connection is necessary for adding and activating an eSIM. Installation might fail if the connection is weak or intermittent. Using a VPN can also lead to this error.
• Expired QR code: Some eSIMs have a limited validity period for scanning. This might happen if you purchased the eSIM well before your trip.
• Unclear QR code or scanning issues: Sometimes the QR code may be unclear, your phone's camera may have issues, or you might be trying to scan the code in poor lighting conditions. Although rare, these factors can also cause this error.
• Incorrect information during manual installation: If you are entering the "SM-DP+ Address" and "Activation Code" manually, incorrect entries can lead to this error.

How To Fix

If you encounter this error while using a travel eSIM, you might have already added the eSIM to your phone but not activated it yet. Follow these steps to check and resolve the issue:

1. Check if the eSIM has already been added: For iPhone users, go to Settings > Cellular > SIMs.

   Verify if there is any new eSIM added to your phone other than your previous eSIMs. The "secondary" will be the newly loaded eSIM.

2. Activate the eSIM:
   1. Enter the eSIM and turn on the line.

      You can modify the label of this line to something like "Simbye" or any other name you prefer.

   2. Turn on the line for the eSIM.
   3. You may need to enable roaming. Most travel eSIMs require roaming, though some with local IPs do not. Check the product details for specific requirements. Restart your phone or toggle airplane mode to reconnect to the local network.
3. Check the eSIM ICCID: Confirm the eSIM is installed successfully by going to Settings > General > About. Scroll down to find the ICCID listed.

   Look for the secondary SIM line (IMEI2) and check the ICCID, which is the Integrated Circuit Card Identification number for this line.

Additional Solutions

• If the eSIM is not listed in the SIM section, restart your phone and try scanning again.
• Install the eSIM in a location with a stable internet connection. Turn off any VPN if you are using one.
• Delete any old eSIMs that you no longer use to simplify the addition of new ones.
• If scanning the QR code fails, manually enter the correct "SM-DP+ Address" and "Activation Code".
• Contact Simbye for further assistance if you are unable to resolve the issue.

PDP Authentication Failure may arise from eSIM-related issues, particularly concerning its validity or settings. To troubleshoot this issue, follow these steps:

1. Ensure you have remaining valid data on your eSIM.
2. Confirm that your Access Point Name (APN) is configured correctly according to the installation instructions.
3. Verify that you are connected to a network supported by your eSIM. You can find the supported network name on our website or within the Simbye App.

If all these are in order and you still encounter the issue, try restarting your device. For detailed instructions on setting up your APN, refer to our guide on “How do I set up my APN?” to ensure proper configuration. All of Simbye eSIM’s have an automatic Access Point Name (APN) and so manual programming is not necessary.

However, if you do want to check or manually configure the APN, follow the steps below:

iOS:

1. Go to Settings
2. Mobile/Cellular Data
3. Under Mobile/Cellular Data plans select your eSIM
4. Mobile/Cellular Data Network
5. In the Mobile/Cellular Data APN field, type drei.at

Android:

1. Go to Settings
2. Network & Internet section
3. Mobile Networks
4. Access Point Names
5. Type the new APN settings, drei.at

The “Unable to Complete Cellular Plan Change” message is an installation error that indicates that the installation of your eSIM hasn’t progressed correctly. This can happen for various reasons, including:

• Having more eSIMs than your device can support.
• Trying to reinstall an eSIM that has already been installed.
• Poor internet connection during the installation.
• Having mobile data turned off in your device settings.

If you encounter this error repeatedly, please take a screenshot of the message and reach out to Simbye Help Center for additional assistance in resolving the issue.

If your device has been unlocked recently and you’re experiencing issues with eSIM support, it’s possible that your carrier has temporarily deactivated this feature as a security measure. To solve this issue, we recommend contacting your mobile carrier for assistance in reactivating eSIM functionality.

3. Go to iPhone Settings > Mobile Data/Cellular > Secondary/Simbye - and make sure that Network Selection is automatic.
4. Go to iPhone Settings > Mobile Data/Cellular > Secondary/Simbye - turn off LTE mode, switch to 3G only.

Note: Do not remove the Simbye profile and do not scan the QR code again, as these actions can delete the predefined settings.
