Well, this might be of interest to some people.
I spoke to Telstra about VoLTE access a few weeks ago.
They explained that the access tests when first connected to the network are different now.
Anyway, I ran the same tests as I ran in the posts I made up above, using my Optimus 2.
Made sure that only only LTE was available from cellular.
Turned off Wi-Fi and cellular data.
VoLTE is now working.!!
This is significantly good news for us.
Especially here in Australia because I ran these tests at the beginning of the year and volte was definitely not working.
I suspect that something has been done due to the fact that 3G will be turned off around three weeks from now. People need to be able use 4G (VoLTE and LTE) so requiring special certificates was going to make it much more difficult.
I will follow up with testing the LEM 14, LEM 15 and LEM 16, and the Prime 2.
This is a great start and Iām hoping that we can now be ok when 3G is completely gone.
Iāll keep you posted.
Cheers

By the way it would be very helpful if other people who have the Opt 2 or similar can follow the steps I have spoken about, and share their results.
Thanks

I can confirm the Lemfo Lem 16 can now make voice calls again in the uk on 3 networkā¦i didnt have to alter any settings or type dialler codeā¦i inserted my sim and tested today and it automatically workedā¦i have also tested your dialler code method above with an A8.1 full android watch today (DW99 Type)ā¦and no such luck , it still wont make voice calls ā¦but sends messagesā¦i followed all your steps suggested
Thanks.
Thatās great, but has 3G been disabled already in the UK?
The only reason to follow my steps is to prove that you can use 4G VoLTE once 3G is disabled.
If 3G has already gone in the UK - you have no worries. Sounds like you have it working.
However, if 3G is not off yet (like here in Australia - we have 3 weeks to go) the watch will automatically switch from 4G to 3G for voice calls.
Voice calls work as always.
You can see this happening if you take a logcat during a call.
If you punch in the code I gave and disable all options apart from LTE and turn Wi-Fi off, you can easily prove that the watch will make calls over VoLTE because if it canāt, calls will just fail.
After you set to LTE only I mean.
If it works then great 
Unfortunately I havenāt checked the status of 3G in the UK so I donāt know if it is still working there or not.
This whole exercise is to find out how your watch is going work once the 3G bands are turned off completely.

some networks in the UK have already switched off 3gā¦3 network are switching off by the end of this year 2024ā¦2 months ago my lem16 wouldnāt make voice callsā¦so i assume 3 network which i use have already started to switch offā¦so i havenāt used my lem 16 for 2 monthsā¦then today i switched it back on, inserted the sim and its now making voice calls,when it previously didntā¦could it be possible as you mentioned earlier in the thread that they have somehow changed the access tests and my lem 16 is now using volte to make voice calls
also when using the dialler code on the lem 16 nothing happensā¦it doesnt bring up any settingsā¦its just blank
also i have just checked and 3G from the 3 mobile network which i use is no longer available in my areaā¦so it has been switched offā¦so i can confirm the Lem 16 must be using volte 4G to make voice calls nowā¦as i said before 2 months ago it wouldnt workā¦images showing 3G unavailable ā¦and 4G working fine

Thatās good news.
I will see what the different code for the dialler is for LEM 16.
It works on other Unisoc devices but maybe not the Z40.
Sounds like itās working anyway.
So it can only be good news I assume
Itās definitely possible that some of the older, stricter carrier checks have been retired to make the (letās face it, forced) transition to 4G VoLTE a bit smoother for customersā¦
Fingers crossed it remains this way.

Fun fact: Ye auld 3G networks been switched off fully in Germany mid 2021 already. What happened at the time was a flood of Android phones that were not supporting 4G/LTE on the secondary markets, e.g. eBay & Co. If you are living in a country where 3G still exists, but being switched off now, the same might happen there. Since many people did not understand the implications of this switch, good deals were to be had for used phones/watches supporting 4G/LTE as well

2 posts were merged into an existing topic: Android 11 is here! Lokmat APPLLP 2&4 Pro and LEM16 Z40 models
thinking of getting a vwar nebulaā¦small question for those who have one alreadyā¦as it is A11 can you put watchfaces on it in the traditional way (straight in the clockskinfolder)?
thanx for the reply
Nope, you will need universal launcher for that.

Hi there,
Oh well, I thought why not me ? So got mine. Named Maze Speed PDG Watch Q668, just received and configuring it. I already noticed the poor quality of the cameras but I didnāt buy it for shooting. The interface isā¦ ugly. Sorry to read custom watchfaces donāt work. Iāll see with universal launcher tutorials if it is worth trying it.

got mine tooā¦been playing around with itā¦batterylife is terribleā¦worst of all the watches i have hadā¦have looked for apps to uncheck in the background but even thenā¦no more than 6 hours of standbytime, without real usageā¦
Oh boy thatās scary ! I tried to see how to deactivate apps in the background but Not sure how to.
