I just purchased one and this is happeing

 

Sounds like it's working as intended in that case lol

@linux you got a bargain. I paid $5 🤣

Linux:

 

HappyPhone 9000 you bought for $2 from Temu won't make a voice call after 4:17pm on every even-numbered Tuesday

 

@SaltyNZ Can you please look into this issue for me? I just purchased one and this is happeing

 

🤣

Speaking as someone who's been eye-ball deep in tech since the 1960's... anyone remember building Heathkit shortwave receivers & the Sinclair Cambridge (a few years before the ZX80)?

Over those decades, I recall some minor interop difficulties arising in what were clearly minor backwaters of tech... in PC LAN cards... in HDCP... in global TV programming... in radio frequency use - so modern tech teams allowing a cluster-fk in something as unimportant as person-to-person communications is sad - but nothing new.

My dad spent his life working for ICAO - which is an (unfortunately rare) example of a timely (1947) and effective effort to enforce a working and standardised global environment for a very technical field - civilian aviation.   

So getting international buy-in on staying on the same page is possible in tech - just not seen as particularly important unless lots of lives are at stake.  

The problem is you get countries mandating their own crap that telcos have to do differently to the rest of the world because that is how things have always been done there. Cough Australia Cough. The telcos will then request specific software from manufacturers to deal with their nonsense and then you have fragmentation.

The only manufacturer that seems to have the ability to say no to this is apple. And then people get upset when they cant use their watch on a certain telco because they have not partnered with apple so you cant win either way.

Telcos need to accept that they are just a data provider now and stop being difficult with respect to their legacy services.

We don't try to stop you running your own SIP service over mobile data (or any other OTT service, for that matter) if that's what you want. The only catch is that in VoLTE and VoNR the RAN and the IMS core work together to give you a guaranteed QoS for the duration of the call, and emergency calls (as with CS) use a different access procedure that will literally boot someone else's call off to allow the emergency call if the site is congested.

You won't get that if you roll your own voice service, but otherwise feel free if that's what you prefer.

Replying to two threads:

freitasm:

 

The problem is the phones not having the profiles needed when attached to one network or another. Nothing to do with the network communicating to each other.

 

SaltyNZ:

 

3GPP chose to build their VoIP service on top of SIP. The great thing about SIP is that there are about a thousand different ways you can accomplish a call scenario. The bad thing about SIP is that there are about a thousand ways you can accomplish a call scenario.

 

So, what's the cheapest unlocked phone where I can run an open-source dialler and load the SIP profile for network that I'm using?  What's the recommended way of retrieving the SIP profile for the network that I'm using?  In asking these questions, I may not be very hopeful :-)

Edit: stray line breaks.

I guess the easiest answer might be: what's the cheapest phone that Skinny (or Spark) sells that does what you're seeking?

freitasm:

 

If a phone does not have the proper profiles for VoLTE in a country then 4G will still be used for mobile data and SMS, but any voice call requires a 3G network to connect.

 

It could be more granular than that, A specific phone might only have one carrier profile within a country but not another carrier

And if the phone manufacturer doesn't put the profile for one network into its software but puts it in for another then the phone has to be legally blocked from all networks in Australia

Total shambles!

Sorry, I thought I have been more explicit about this in the other posts. But yes, it comes down to individual operator profiles too.

your concept of an unlocked phone still seems to be something you can pop any sim into and expect it work on any network after all 3G has been shutdown. the answer to that would still be the iphone - whatever the current cheapest variant available is.

if you want to stay on skinny/spark, with no guarantee that it will work in the 1NZ and 2D networks, should you try it... simply pop into one of their shops/kiosks, and find one you like that also fits your budget. a quick look at the website suggests a few candidates - Galaxy A06 5G, for one.

of course, as you haven't confirmed that you have 2D network connectivity issues where you live/play... i'd still consider popping a 2D sim (for $2) and go on the same $8 prepay monthly, albeit giving up 100MB of data (vs Skinny's $8) each month. not sure if that's a dealbreaker, but it might give you a few months to save up for a new, maybe even better-specced, phone, if you still want to move providers. a lot of us don't just have a few hundy to spend on another phone. that's perfectly understandable.

@jfw01 That information is not available to the end of user, if you want a phone that is cost effective, and will work on any network in NZ look for a refurbished iPhone SE like this
