hio77:

Years ago when VoLTE first came out here, most if not all providers needed to have it provisioned before it would be available to devices, among other reasons that allowed the network to ensure that they didnt push out an change to devices that might have issues with 111 calls etc.

I think One NZ which the OP is on is automatically provisioned. On a Huawei Nova 5T, the VoLTE icon showed up right away, you could call 777 to activate SIM, whereas after inserting the Skinny SIM there was no VoLTE icon to be seen even though it's listed as supported on the Spark / Skinny website. Other than activating via website, not sure how one would activate by calling 456 after 3G shutdown.

The phone has root magisk and added modules

and root explorer.. if it was just a file change

like MDN it could be fixed easy.

AI said get simcard updated in case but it did

Are you typing your messages on your phone or a tablet or something? The formatting looks strange.

Hi Paul.

A One NZ Smart M26 is $99.

I want you to budget for this phone and I want you to save and get this and stay on the One NZ network. A retail store will help you not only set it up but ensure it can make calls before you leave. Whilst I am ex One NZ, I have a few good friends, especially around retail, customer and network space. I can genuinely tell you that these devices will not get support ever. You need to upgrade.

Spark will shut down their 3G network tonight. 2degrees and One NZ's 3G network are already off which means from tomorrow you will be completely unable to make emergency calls. So no calling 111 until you sort this out. Let alone anyone else calling you.

Even if you get your Xperia working with Pixel IMS, I need to abundantly make this clear. You are still unsupported. If it starts doing dodgy things you will get 0 support. If it works you will still get 0 support. If you make a 111 call and you're not in One NZ coverage, that call is LIKELY to fail.

The Smart M26 is supported by One NZ 100%. This is the cheapest newest handset that you can use for calls, texts and it is modern enough but not bloated.

I genuinely want you to take this option as no provider is going to support either device that you currently have. Both are unsupported. Both are probably highly out of date and with 3G going for good tomorrow at 12:01am...

I will also stress that unless you were on Supa Prepay from 15 years ago. IMS, VoLTE(which you absolutely need for calling) is already preprovisioned and ready to go. Your device is the problem.

I am sorry that this is a hard response to read, however none of the big three can maintain 3G services so your legacy devices can continue to work.

Ramblings from a mysterious lady who's into tech. Warning I may often create zingers.

thanks I know cheap ones exist.. but i rather use that cash to spend

on a decent phone that should last 3-5 years

I was shocked to hear apple ipad battery lasted 8 years

over chinese tablets seems they can built tech to last

if they want too :) and swappable batteries inside!

(as for my watch phone, Chinese probably messed up?

or just not certified as AI says

{ https://www.chinesesmartwatches.com/s999-4g-smartwatch/

specs above and image

While some listings for the

S999 Smart Watch

(also known as the

LOKMAT APPLLP Max

) claim "full VoLTE compatibility", most technical spec

sheets and user manuals omit it, focusing instead on

standard 4G LTE network support.

Why "No VoLTE" is a Common Concern

Carrier Whitelisting: Many carriers (especially in the US) only allow VoLTE on "certified" devices. Unbranded Android watches like the

S999

often lack these certifications, causing them to drop to 3G/2G for calls.
Firmware Limits: Many of these watches ship with "Stock Android" shells that don't always have the IMS (IP Multimedia Subsystem) settings correctly configured for VoLTE toggling.

}

but at time of buying I thought 4G good to go.. wasnt

til I found out about also voltE needed! too late now)

but I stick with whattsapp meantime on it

and sms. I dont expect reg calls on it..

unlike the reg phone.

111 calls not worried about working. too bad I guess
