Your device is not within cellular coverage.
There’s an issue with the ALDI Mobile SIM.
The mobile network/APN settings are wrong.

Let’s investigate the most effective solutions to resolve error “0” on ALDI Mobile!

ALDI Mobile Error 0 – 8 Quick Solutions

Tip: Follow the steps chronologically!

1. Reinsert the ALDI Mobile SIM

The easiest solution to error codes with your ALDI mobile service is reinserting the ALDI SIM card to refresh the service.

A connection fault between the SIM and the ALDI mobile could result in an error 0 and interrupt your cellular service.

Follow these simple instructions to reinsert the provider’s SIM card:

Locate the SIM compartment on the device’s side panel.
Insert a paperclip or a SIM tool to pop-open the SIM tray.
Eject ALDI’s SIM card from the tray of your mobile device.
Verify there is no dust or obstructions on the device’s tray.
Clean the SIM card using a soft cloth to remove any dust.
Reinsert the ALDI SIM and push the tray back into the slot.

A potential defect or signs of wearing on the SIM card should be reported to ALDI as soon as possible.

Once the submission is reviewed, you will receive a brand-new SIM chip as soon as possible.

2. Check the Mobile Cellular Coverage

The occurrence of the error code “0” on ALDI might also be caused by improper cellular coverage of the mobile device.

Nearby signal obstructions, cellular dead zones or reductions in signal strength can severely impact your mobile device’s reception and cause the ALDI error “0.”

Here are some practical tips to improve the cellular connectivity of your device:

Switch to “3G” and then to “4G” again or vice-versa.
Power off your mobile device and charge the battery.
Relocate your ALDI mobile from nearby obstructions.

At least 2 bars are recommended for optimal performance on ALDI mobile.

Note: The cellular indicator widget on the top of your mobile displays the current strength of the signal in bars.

3. Toggle the Airplane Mode ON/OFF

A proven way to reset the cellular coverage of your mobile device is to toggle the Airplane mode on and off.

While activated, the Airplane Mode deactivates all cellular services of your mobile device, including using the ALDI mobile data and sending or receiving cellular calls.

Let’s learn how to toggle the Airplane mode on Android and iOS devices!

On iPhone, swipe downwards from the homepage and tap the “Airplane” icon.
On Android, go to Settings → “Airplane” or “Do Not Disturb” and tap the slider.

Wait for a rough 20 seconds while the airplane mode is activated, and then turn off the feature to allow your device’s cellular connection.

Determine whether the ALDI Mobile error “0” persists.

Note: Forgetting the Airplane Mode enabled will permanently restrict the mobile network access.

4. Change the Default Messaging App

An issue with the device’s default messaging app could result in the occurrence of the ALDI mobile error “0.”

The next step is to select an alternative messaging application in your device’s global settings and attempt to send an SMS or MMS to determine if the ALDi error is still there.

How to Change Default SMS App On Android?

Download or purchase a compatible messaging app.
Open the “Settings” app on your mobile Android device.
After that, go to “App & Notification” → “Default apps.”
Select “SMS app” and wait for the platform list to appear.
Select the applicable SMS service from the list of apps.

How to Change Default SMS App On iPhone?

It is not yet possible to change the default messaging app on your iPhone device.

However, you should still update the default “iMessages” app to the latest version since outdated firmware can cause issues with incoming or outgoing SMS or MMS packets.

Note: You can update apps on your phone through the Google Play Store or App Store!

5. Check for Local ALDI Outages

There could be a system-wide ALDI outage, rendering the entire cellular network unavailable for an undetermined amount of time.

ALDI uses a live map of Australia to visualise the status of cellular service and provide all users with outage and maintenance information about their area.

Here’s how to check the cellular ALDI coverage in your area

Go to ALDI’s Network Coverage map on your browser.
Select the “Find address or place” in the map’s section.
Specify the type of coverage on the map (3G, 4G or 5G.)
Type in your current map location and press on “Search.”
Wait until the ALDI outage identifier displays the results.

Note: Reported outages are displayed in red colour on ALDI’s coverage map!

6. Re-configure Your APN Settings

Not setting ALDI’s APN settings on your mobile device may disallow the usage of extensive cellular services, such as calling and sending messages over cellular.

So, the next step is to re-configure your device’s APN configuration and correct it as per the ALDI’s network APN.

Where to Find an APN on Android?

Go to Settings → Wireless Connections → Advanced → Access Point Names.

Where to Find an APN on Apple’s iOS?

Go to Settings → Cellular → Mobile Network → Mobile Data Options → New APN.

ALDI Mobile APN Settings
Name	Mobile Data
APN	mdata.net.au/Telstra internet
Proxy	<Empty>
Port	<Empty>
Username	<Empty>
Password	<Empty>
Server	<Empty>
MMSC	http://mmsc.mdata.net.au:8003
MMS Proxy	10.1.1.180
MMS Port	80
MMS Protocol	IPv4 or IPv4/IPv6
MCC	505
MNC	01
Authentication	<Empty>
APN Type	Default, dun,supl,mms

After re-configuring the APN settings of your ALDI mobile, save the changes and exit the configuration section.

Your device will automatically adjust the carrier and network settings.

Reminder: You will still have to configure your Wi-Fi and Bluetooth, though!

7. Check Mobile for Carrier-Lockout

Your mobile phone might be service-locked if you’ve leased the device while signed with an alternative carrier, and perhaps that’s why you can’t send a message with ALDI mobile error 0.

All devices purchased through a mobile subscription plan remain assigned via APN to the carrier and will not accept alternative SIM cards, such as the ALDI Mobile chip.

How to Check if a Mobile Device is Carrier-Locked?

To check on your iPhone, go to “Settings” → “General” → “About” → “Carrier lock.”
On Android, go to “Settings” → “Network” → “Mobile Network” → “Network Operators.”

Every carrier locks the sold mobile devices for a predefined amount, disallowing them to be used on an alternative network.

The only way to determine whether the device is locked is by contacting the previous carrier and providing the device’s unique MAC address.

Note: You can’t unlock carrier-locked devices!

8. Reset the Device’s Network Settings

Restoring the default network settings of your ALDI mobile holds a high chance of resolving any recurring service error codes.

The ALDI error “0” might result from improperly configured cellular, Wi-Fi or even Bluetooth network settings of the ALDI-powered mobile.

Network Refresh For iOS?

Go to “Settings” → “General” → “Transfer or Reset [Device]” → “Reset” → “Network Settings Reset” and to start, tap on the “Confirm” button.

Network Refresh Android?

Go to “Settings” → “Reset” → “Reset Network Settings,” and confirm the network data reset by typing down your device’s PIN and selecting “Verify.”

Note: The APN settings of your ALDI Mobile will automatically re-adjust after the reset!

Quick Recap:

ALDI mobile error 0 can be fixed by changing the default messaging app or correcting the APN settings on your mobile.

If that does not work, reinsert the device’s SIM card, optimise the cellular signal, and if nothing helps, reset the ALDI mobile network settings.
