Suggested Troubleshooting Steps

Is the device IMEI blocked due to the 3G shutdown?

Does the device function as intended use stock Google firmware?

[deleted] Do you have any information about only whitelisting local IMEI and blocking International ones?

If you’re using a device that was set up for another country (i.e. you bought it overseas, it was imported, or it’s second-hand and you’re not sure where it’s from, or it may be refurbished), it may be blocked from connecting to our network or experience reduced coverage.

If your device does not support Voice over LTE (VoLTE) including VoLTE Emergency Calling, your device will be blocked from accessing our mobile network, in line with changes to the Telecommunications (Emergency Call Service) Determination

This paragraph seems to suggest that overseas devices can be blocked/have reduced coverage even if they support VoLTE and VoLTE Emergency Calling and is a separate thing than the 3G shutdown.

Not all cellular devices support 4G frequency Band 28 (700Mhz) which would explain why some devices will be blocked on the Telstra Australia network.

Different model variants of the same device can support different cellular frequencies. Older Samsung devices are a good example of this.

I don't see an issue with Pixel hardware after looking at the "Network" specifications.

My understanding is the IMEI blocking is based on a functionality challenge of the device.
If the device cannot meet the following criteria it is blocked:
"To connect to our mobile network (Telstra Australia) you will need a device compatible with 4G frequency Band 28 (700Mhz) and Voice over LTE (VoLTE) including VoLTE Emergency Calling"

"The Australian Government has made a regulation – a law – that requires us (Telstra Australia) to prevent mobile phones that rely on 3G for emergency calls (including Triple Zero (000) ) from accessing our network. To comply with this law, Telstra has blocked mobile handsets that are non-VoLTE (4G data, 3G voice) and VoLTE but require 3G for Triple Zero from our mobile network on Monday 28 October 2024."
