Buying a phone from overseas - what do I need to know so that it is compatible with use in Oz with a Telstra SIM?

[markis10]

It won’t confirm the compatibility of the handset with the local Telstra network (although the goto handsets are pretty decent compared to the old days of needing specific hardware in the USA and Japan (as examples)).

But if the new handset recognises the Telstra SIM and connects / roams, that ought to be a good sign that the handset isn’t locked to another carrier and the Telstra SIM is working in the handset.

Google could help to check the model is comparable with Oz (as well as infos suggested earlier).

You are confusing two different things and providing out of date info.
Sim locking is just a commercial thing, putting in your Telstra SIM will confirm that’s not in place however it won’t confirm if it will work back home.
With the shutdown of the 3G network new measures are in place to ensure phones are compatible with 000 and the network it’s being used on. A phone registering on the network calls home and provides a heap of details to the network operator, allowing the provider to see if it’s compliant with Australian Law with regards not using 3G for emergency calls that was brought in last year. See Australia’s 3G Shutdown - Telcos to Block Working 4G/5G Phones!

Plenty of phones that appear to be 100% compliant are being blocked.

No, We’ve all mentioned the network comparability issues and the potential pitfalls of buying a handset OS.

One would have to have a very very old phone if it was solely using 3G for calls. 3G launched way back in 2003; 4G launched in 2011and pretty much every phone released since 2012 in Australia was 4G compatible.

There is only so much room on cell towers, operators retire old tech to re-use the space for newer tech once critical mass has been reached for the newer techs.

Most phone manufacturers so only provide software (OS and Security) updates for 5 years, it is imo unrealistic to expect a mobile phone to have a useable lifespan of more than 5-6 years.

There was a heap of notice before the analogue, 2G and then 3G network shutdowns . If you are after a basic 4G phone you can get them from $39 like the Telstra T Essential from Big W. If you need a bit more grunt for apps you have android options from$89 at Officeworks.

Looking for a reasonably high performing dual-sim rugged phone - its just going to take some time to research it to try to find something local. Unfortunately the range of overseas phones that meet my requirements is good, the range of what is available in Australia is rather less so.
