Why is your ALDI eSIM not working?

If your ALDI eSIM isn’t working, it may be because of a setup or network configuration issue. Errors can happen during your eSIM activation, when switching devices, or if you haven’t adjusted your mobile settings properly.

Some other possible reasons why your ALDI eSIM isn’t working include:

You do not have an eSIM compatible phone.
The QR code wasn’t scanned during setup.
You installed the eSIM but did not activate it.
Your mobile data or roaming is switched off.
Your phone isn’t connecting to a mobile network automatically.
Your device’s Access Point Name (APN) settings are missing or incorrect.
You’ve reached your eSIM data limit.

How to fix ALDI eSIM issues

To fix your ALDI eSIM issues, you need to find out the error source and follow the steps below to solve it.

1. Check if your device supports ALDI eSIM

Check your device’s settings to see if it supports eSIM and is unlocked to use with another carrier. ALDI eSIM only works on eSIM-compatible phones.

To check your eSIM compatibility on iPhone:

Go to Settings > Mobile > Add Mobile Plan. If you don’t see this option, your device doesn’t support eSIM.

ALDI eSIM works on iPhone XR and newer, except for some models sold in mainland China.

To see if your Android device supports eSIM:

Go to Settings > Network & Internet > SIMs or Mobile Network. If there’s no option to add an eSIM or scan a QR code, your Android phone isn’t eSIM compatible.

The latest Android devices, including the Google Pixel 4+, Samsung Galaxy S20 and above, and Motorola Edge, support eSIM.

2. Reinstall the ALDI eSIM profile

Reinstalling your ALDI eSIM profile removes the existing profile and lets you set it up again from scratch.

For iPhone:

Go to Settings > Mobile Data or Cellular.
Select your ALDI eSIM.
Tap Remove Mobile Plan.
Restart your iPhone.
Scan the ALDI QR code and follow the activation steps.

For Android:

Go to Settings > Network & Internet or Connections.
Tap on SIMs or Mobile network.
Select the ALDI eSIM and choose Remove or Delete.
Restart your phone and install your ALDI eSIM by scanning the QR code.

Note: You can only use the ALDI eSIM QR code for a one-time activation. Contact ALDI Mobile customer support via their contact page to request a replacement before reinstalling your eSIM.

3. Restart your phone after installation

Restarting your phone finalises the eSIM configuration and can solve common errors like missing signal bars, slow data, or eSIM activation delays.

4. Turn on mobile data and data roaming

Turn on your mobile data in your phone settings. You can’t connect without activating your mobile data, even if the eSIM is installed correctly.

You must turn on data roaming on your device as well if you are travelling abroad. Just note that ALDI Mobile’s international roaming runs on a pay-as-you-go basis, so you’ll need an available balance to connect.

Turn on data roaming on your iPhone with these simple steps.

5. Enable and disable Airplane mode

Turn on airplane mode, wait 10-20 seconds, and then switch it off. By using flight mode, you can reset your network connection and fix temporary signal issues.

6. Manually select a local network

If your device doesn’t connect to a network automatically, try selecting a local network manually.

For iPhone:

Go to Settings > Mobile Data or Cellular > tap Network Selection > Turn off Automatic and select a suggested carrier manually.

For Android:

Go to Settings > Network & internet or Connections > tap Mobile network. > select Network operators > turn off Select automatically and choose a network from the list manually.

7. Update or reset your APN settings

Updating or resetting your APN can often fix the problem. APN settings tell your phone how to connect to your mobile network for data. If these settings are missing or incorrect, your eSIM may not connect to the internet.

For iPhone:

Go to Settings > Mobile Data or Cellular.
Tap Mobile Data Network.
Check the APN details provided by ALDI Mobile.
If needed, update the details or clear them and restart your phone.

If you don’t see the option to edit your APN settings, don’t worry; some eSIM carriers automatically configure them during installation, so manual changes may not be needed.

For Android:

Go to Settings > Network & internet or Connections.
Tap Mobile network > Access Point Names.
Select the ALDI APN or tap Add to enter the correct details.
Save the settings and restart your phone.

If you’re unsure of the correct APN details, it’s best to check ALDI Mobile’s support site or contact customer support before making changes.

8. Reset your network settings

If none of the steps above work, resetting your network settings can help. This clears saved mobile, Wi-Fi, and Bluetooth connections and forces your phone to set them up again from scratch.

On iPhone:

Go to Settings > General > tap Transfer or Reset iPhone > select Reset > Reset Network Settings > Enter your passcode to confirm.

On Android:

Go to Settings > System or General management > tap Reset options > select Reset Wi-Fi, mobile & Bluetooth > confirm the reset.

After resetting, restart your phone and reconnect to mobile data. You may need to re-enter your Wi-Fi passwords, but this step often fixes most eSIM connection issues.
