Vodafone is alerting users of older iPhones, specifically models iPhone 6 through iPhone X, about a critical software update necessary to ensure they can make emergency calls. The update addresses a potential inability to connect to emergency services when dialling Triple Zero, making this a safety issue rather than just accessing new features.
The core issue lies in VoLTE (Voice over LTE), the technology that enables 4G calling. As Australia shuts down its 3G networks, phones are increasingly reliant on VoLTE for making calls. Older iPhones that haven’t been properly updated may have VoLTE disabled, which could prevent them from connecting to emergency services in critical situations.This isn’t about convenience, it’s about whether your phone will work when you need to call for help.
Affected Devices
| iPhone Model | Required Action | Minimum iOS Version |
|---|---|---|
| iPhone 8, 8 Plus, X | Verify software version | iOS 16.7.12 or later |
| iPhone 6, 6 Plus, 6s, 6s Plus, 7, 7 Plus | Update software AND enable VoLTE | Latest available iOS + VoLTE enabled |
Carrier Response
Vodafone isn’t the only telecommunications provider addressing this issue. All major Australian carriers are taking measures to ensure customers can reliably contact emergency services:
Telstra
- Protected devices: Customers who updated to iOS 17.4 or later—VoLTE cannot be disabled on these versions
- Older iOS versions: Users should update immediately and contact Telstra to have devices unblocked if necessary
Optus
- Active monitoring: Tracking devices on the network for compliance
- Direct contact: Will reach out to customers whose devices require attention
Vodafone
- User alerts: Notifying affected customers directly
- Unblocking process: Provides online form for customers who update after blocking
How to Fix Your iPhone
Step 1: Check and Install Software Updates
- Open the Settings app
- Go to General
- Select Software Update
- Install any available updates
Step 2: Enable VoLTE (iPhone 6 through 7 Plus)
- Open the Settings app
- Select Mobile
- Choose Mobile Data Options
- Select Enable 4G
- Tap Voice & Data
- Toggle on VoLTE
Step 3: Verify Emergency Call Capability
After completing the updates, confirm that your device can make calls successfully. If you experience issues, contact your carrier immediately.
Legal Requirements and Network Blocking
Australian telecommunications companies have a legal obligation to ensure devices on their networks can reliably make emergency calls. Key points to understand:
| Aspect | Details |
|---|---|
| Legal Obligation | Carriers must ensure devices can make emergency calls |
| Warning Period | 28 to 35 days notice before blocking non-compliant devices |
| Blocking Criteria | Devices that don’t meet emergency call requirements may be blocked |
| Unblocking Process | Available after updating software—contact your carrier or use online forms |
Context: The 3G Shutdown
This issue stems from Australia’s transition away from 3G networks. Key implications include:
- Network evolution: Carriers are decommissioning 3G infrastructure to reallocate spectrum for 4G and 5G
- VoLTE dependency: Without 3G, phones must use VoLTE for voice calls, including emergency services
- Older device vulnerability: Devices that relied on 3G for calls need proper configuration to work on 4G networks
Similar Past Issues
While distinct from a past issue affecting Samsung phones—which involved older models being hardwired to search for non-existent 3G networks when dialing emergency services—the potential consequences are equally severe. In both scenarios, proactive measures are required to guarantee phones can connect to emergency services when needed.
Broader Implications
The 3G shutdown highlights challenges that come with technological progress:
| Challenge | Impact |
|---|---|
| Older Device Support | Users with aging hardware face potential service disruption |
| Emergency Access | Safety-critical services must remain reliable during network transitions |
| User Awareness | Many don’t realize their phones need updates to maintain basic functionality |
| E-waste Concerns | Network changes may force premature device replacement |
What You Should Do Now
If you own an iPhone 6 through iPhone X in Australia:
- Check your iOS version immediately: Go to Settings → General → About
- Update if necessary: Install the latest available iOS version for your device
- Enable VoLTE: Follow the steps above to ensure VoLTE is turned on
- Test your phone: Make a test call to verify functionality
- Contact your carrier if blocked: Use their unblocking process if you’ve already been disconnected
- Check other devices: Don’t forget smartwatches and other connected devices that might be affected
This isn’t a typical software update reminder—it’s a safety issue that could prevent you from reaching emergency services when you need them most. The combination of Australia’s 3G network shutdown and VoLTE requirements means older iPhones need specific configuration to work properly.
The good news is the fix is straightforward: update your iOS and enable VoLTE. The bad news is that many users may not realize their phones have this vulnerability until it’s too late. If you or someone you know uses an older iPhone in Australia, taking these steps now could literally be lifesaving.
This situation also serves as a reminder that network infrastructure changes have real-world consequences for device compatibility. As carriers continue evolving their networks toward 5G and beyond, similar issues may arise for other devices. Regular software updates and staying informed about your carrier’s network changes are essential for maintaining reliable service, especially for emergency calls.
