Essential requirements
Your new device must support VoLTE for making calls, including emergency calls, over 4G. It should also be compatible with the Telstra Wholesale network's 4G bands for optimal coverage.

Network bands
For the best coverage, ensure your device supports these key 4G bands:

• 700MHz (B28), most important
• 1800MHz (B3)
• 2100MHz (B1)
• 2600MHz (B7)

Where to check
You can verify device compatibility through:

• Manufacturer's website
• Device specifications page
• Retailer during purchase
• Product manual

For phones
When buying a new phone, specifically confirm:

1. VoLTE/HD calling support
2. Emergency calling over 4G
3. Network band compatibility

For data-only devices
If your device doesn't make calls (like tablets or IoT devices), just ensure it supports 4G data on compatible network bands.
